GPIO Mappings
|
||||
=============
|
||||
|
||||
This document explains how GPIOs can be assigned to given devices and functions.
|
||||
Note that it only applies to the new descriptor-based interface. For a
|
||||
description of the deprecated integer-based GPIO interface please refer to
|
||||
gpio-legacy.txt (actually, there is no real mapping possible with the old
|
||||
interface; you just fetch an integer from somewhere and request the
|
||||
corresponding GPIO.
|
||||
|
||||
Platforms that make use of GPIOs must select ARCH_REQUIRE_GPIOLIB (if GPIO usage
|
||||
is mandatory) or ARCH_WANT_OPTIONAL_GPIOLIB (if GPIO support can be omitted) in
|
||||
their Kconfig. Then, how GPIOs are mapped depends on what the platform uses to
|
||||
describe its hardware layout. Currently, mappings can be defined through device
|
||||
tree, ACPI, and platform data.
|
||||
|
||||
Device Tree
|
||||
-----------
|
||||
GPIOs can easily be mapped to devices and functions in the device tree. The
|
||||
exact way to do it depends on the GPIO controller providing the GPIOs, see the
|
||||
device tree bindings for your controller.
|
||||
|
||||
GPIOs mappings are defined in the consumer device's node, in a property named
|
||||
<function>-gpios, where <function> is the function the driver will request
|
||||
through gpiod_get(). For example:
|
||||
|
||||
foo_device {
|
||||
compatible = "acme,foo";
|
||||
...
|
||||
led-gpios = <&gpio 15 GPIO_ACTIVE_HIGH>, /* red */
|
||||
<&gpio 16 GPIO_ACTIVE_HIGH>, /* green */
|
||||
<&gpio 17 GPIO_ACTIVE_HIGH>; /* blue */
|
||||
|
||||
power-gpio = <&gpio 1 GPIO_ACTIVE_LOW>;
|
||||
};
|
||||
|
||||
This property will make GPIOs 15, 16 and 17 available to the driver under the
|
||||
"led" function, and GPIO 1 as the "power" GPIO:
|
||||
|
||||
struct gpio_desc *red, *green, *blue, *power;
|
||||
|
||||
red = gpiod_get_index(dev, "led", 0);
|
||||
green = gpiod_get_index(dev, "led", 1);
|
||||
blue = gpiod_get_index(dev, "led", 2);
|
||||
|
||||
power = gpiod_get(dev, "power");
|
||||
|
||||
The led GPIOs will be active-high, while the power GPIO will be active-low (i.e.
|
||||
gpiod_is_active_low(power) will be true).
|
||||
|
||||
ACPI
|
||||
----
|
||||
ACPI does not support function names for GPIOs. Therefore, only the "idx"
|
||||
argument of gpiod_get_index() is useful to discriminate between GPIOs assigned
|
||||
to a device. The "con_id" argument can still be set for debugging purposes (it
|
||||
will appear under error messages as well as debug and sysfs nodes).
|
||||
|
||||
Platform Data
|
||||
-------------
|
||||
Finally, GPIOs can be bound to devices and functions using platform data. Board
|
||||
files that desire to do so need to include the following header:
|
||||
|
||||
#include <linux/gpio/driver.h>
|
||||
|
||||
GPIOs are mapped by the means of tables of lookups, containing instances of the
|
||||
gpiod_lookup structure. Two macros are defined to help declaring such mappings:
|
||||
|
||||
GPIO_LOOKUP(chip_label, chip_hwnum, dev_id, con_id, flags)
|
||||
GPIO_LOOKUP_IDX(chip_label, chip_hwnum, dev_id, con_id, idx, flags)
|
||||
|
||||
where
|
||||
|
||||
- chip_label is the label of the gpiod_chip instance providing the GPIO
|
||||
- chip_hwnum is the hardware number of the GPIO within the chip
|
||||
- dev_id is the identifier of the device that will make use of this GPIO. If
|
||||
NULL, the GPIO will be available to all devices.
|
||||
- con_id is the name of the GPIO function from the device point of view. It
|
||||
can be NULL.
|
||||
- idx is the index of the GPIO within the function.
|
||||
- flags is defined to specify the following properties:
|
||||
* GPIOF_ACTIVE_LOW - to configure the GPIO as active-low
|
||||
* GPIOF_OPEN_DRAIN - GPIO pin is open drain type.
|
||||
* GPIOF_OPEN_SOURCE - GPIO pin is open source type.
|
||||
|
||||
In the future, these flags might be extended to support more properties.
|
||||
|
||||
Note that GPIO_LOOKUP() is just a shortcut to GPIO_LOOKUP_IDX() where idx = 0.
|
||||
|
||||
A lookup table can then be defined as follows:
|
||||
|
||||
struct gpiod_lookup gpios_table[] = {
|
||||
GPIO_LOOKUP_IDX("gpio.0", 15, "foo.0", "led", 0, GPIO_ACTIVE_HIGH),
|
||||
GPIO_LOOKUP_IDX("gpio.0", 16, "foo.0", "led", 1, GPIO_ACTIVE_HIGH),
|
||||
GPIO_LOOKUP_IDX("gpio.0", 17, "foo.0", "led", 2, GPIO_ACTIVE_HIGH),
|
||||
GPIO_LOOKUP("gpio.0", 1, "foo.0", "power", GPIO_ACTIVE_LOW),
|
||||
};
|
||||
|
||||
And the table can be added by the board code as follows:
|
||||
|
||||
gpiod_add_table(gpios_table, ARRAY_SIZE(gpios_table));
|
||||
|
||||
The driver controlling "foo.0" will then be able to obtain its GPIOs as follows:
|
||||
|
||||
struct gpio_desc *red, *green, *blue, *power;
|
||||
|
||||
red = gpiod_get_index(dev, "led", 0);
|
||||
green = gpiod_get_index(dev, "led", 1);
|
||||
blue = gpiod_get_index(dev, "led", 2);
|
||||
|
||||
power = gpiod_get(dev, "power");
|
||||
gpiod_direction_output(power, 1);
|
||||
|
||||
Since the "power" GPIO is mapped as active-low, its actual signal will be 0
|
||||
after this code. Contrary to the legacy integer GPIO interface, the active-low
|
||||
property is handled during mapping and is thus transparent to GPIO consumers.

GPIO Descriptor Consumer Interface
|
||||
==================================
|
||||
|
||||
This document describes the consumer interface of the GPIO framework. Note that
|
||||
it describes the new descriptor-based interface. For a description of the
|
||||
deprecated integer-based GPIO interface please refer to gpio-legacy.txt.
|
||||
|
||||
|
||||
Guidelines for GPIOs consumers
|
||||
==============================
|
||||
|
||||
Drivers that can't work without standard GPIO calls should have Kconfig entries
|
||||
that depend on GPIOLIB. The functions that allow a driver to obtain and use
|
||||
GPIOs are available by including the following file:
|
||||
|
||||
#include <linux/gpio/consumer.h>
|
||||
|
||||
All the functions that work with the descriptor-based GPIO interface are
|
||||
prefixed with gpiod_. The gpio_ prefix is used for the legacy interface. No
|
||||
other function in the kernel should use these prefixes.
|
||||
|
||||
|
||||
Obtaining and Disposing GPIOs
|
||||
=============================
|
||||
|
||||
With the descriptor-based interface, GPIOs are identified with an opaque,
|
||||
non-forgeable handler that must be obtained through a call to one of the
|
||||
gpiod_get() functions. Like many other kernel subsystems, gpiod_get() takes the
|
||||
device that will use the GPIO and the function the requested GPIO is supposed to
|
||||
fulfill:
|
||||
|
||||
struct gpio_desc *gpiod_get(struct device *dev, const char *con_id)
|
||||
|
||||
If a function is implemented by using several GPIOs together (e.g. a simple LED
|
||||
device that displays digits), an additional index argument can be specified:
|
||||
|
||||
struct gpio_desc *gpiod_get_index(struct device *dev,
|
||||
const char *con_id, unsigned int idx)
|
||||
|
||||
Both functions return either a valid GPIO descriptor, or an error code checkable
|
||||
with IS_ERR(). They will never return a NULL pointer.
|
||||
|
||||
Device-managed variants of these functions are also defined:
|
||||
|
||||
struct gpio_desc *devm_gpiod_get(struct device *dev, const char *con_id)
|
||||
|
||||
struct gpio_desc *devm_gpiod_get_index(struct device *dev,
|
||||
const char *con_id,
|
||||
unsigned int idx)
|
||||
|
||||
A GPIO descriptor can be disposed of using the gpiod_put() function:
|
||||
|
||||
void gpiod_put(struct gpio_desc *desc)
|
||||
|
||||
It is strictly forbidden to use a descriptor after calling this function. The
|
||||
device-managed variant is, unsurprisingly:
|
||||
|
||||
void devm_gpiod_put(struct device *dev, struct gpio_desc *desc)
|
||||
|
||||
|
||||
Using GPIOs
|
||||
===========
|
||||
|
||||
Setting Direction
|
||||
-----------------
|
||||
The first thing a driver must do with a GPIO is setting its direction. This is
|
||||
done by invoking one of the gpiod_direction_*() functions:
|
||||
|
||||
int gpiod_direction_input(struct gpio_desc *desc)
|
||||
int gpiod_direction_output(struct gpio_desc *desc, int value)
|
||||
|
||||
The return value is zero for success, else a negative errno. It should be
|
||||
checked, since the get/set calls don't return errors and since misconfiguration
|
||||
is possible. You should normally issue these calls from a task context. However,
|
||||
for spinlock-safe GPIOs it is OK to use them before tasking is enabled, as part
|
||||
of early board setup.
|
||||
|
||||
For output GPIOs, the value provided becomes the initial output value. This
|
||||
helps avoid signal glitching during system startup.
|
||||
|
||||
A driver can also query the current direction of a GPIO:
|
||||
|
||||
int gpiod_get_direction(const struct gpio_desc *desc)
|
||||
|
||||
This function will return either GPIOF_DIR_IN or GPIOF_DIR_OUT.
|
||||
|
||||
Be aware that there is no default direction for GPIOs. Therefore, **using a GPIO
|
||||
without setting its direction first is illegal and will result in undefined
|
||||
behavior!**
|
||||
|
||||
|
||||
Spinlock-Safe GPIO Access
|
||||
-------------------------
|
||||
Most GPIO controllers can be accessed with memory read/write instructions. Those
|
||||
don't need to sleep, and can safely be done from inside hard (non-threaded) IRQ
|
||||
handlers and similar contexts.
|
||||
|
||||
Use the following calls to access GPIOs from an atomic context:
|
||||
|
||||
int gpiod_get_value(const struct gpio_desc *desc);
|
||||
void gpiod_set_value(struct gpio_desc *desc, int value);
|
||||
|
||||
The values are boolean, zero for low, nonzero for high. When reading the value
|
||||
of an output pin, the value returned should be what's seen on the pin. That
|
||||
won't always match the specified output value, because of issues including
|
||||
open-drain signaling and output latencies.
|
||||
|
||||
The get/set calls do not return errors because "invalid GPIO" should have been
|
||||
reported earlier from gpiod_direction_*(). However, note that not all platforms
|
||||
can read the value of output pins; those that can't should always return zero.
|
||||
Also, using these calls for GPIOs that can't safely be accessed without sleeping
|
||||
(see below) is an error.
|
||||
|
||||
|
||||
GPIO Access That May Sleep
|
||||
--------------------------
|
||||
Some GPIO controllers must be accessed using message based buses like I2C or
|
||||
SPI. Commands to read or write those GPIO values require waiting to get to the
|
||||
head of a queue to transmit a command and get its response. This requires
|
||||
sleeping, which can't be done from inside IRQ handlers.
|
||||
|
||||
Platforms that support this type of GPIO distinguish them from other GPIOs by
|
||||
returning nonzero from this call:
|
||||
|
||||
int gpiod_cansleep(const struct gpio_desc *desc)
|
||||
|
||||
To access such GPIOs, a different set of accessors is defined:
|
||||
|
||||
int gpiod_get_value_cansleep(const struct gpio_desc *desc)
|
||||
void gpiod_set_value_cansleep(struct gpio_desc *desc, int value)
|
||||
|
||||
Accessing such GPIOs requires a context which may sleep, for example a threaded
|
||||
IRQ handler, and those accessors must be used instead of spinlock-safe
|
||||
accessors without the cansleep() name suffix.
|
||||
|
||||
Other than the fact that these accessors might sleep, and will work on GPIOs
|
||||
that can't be accessed from hardIRQ handlers, these calls act the same as the
|
||||
spinlock-safe calls.
|
||||
|
||||
|
||||
Active-low State and Raw GPIO Values
|
||||
------------------------------------
|
||||
Device drivers like to manage the logical state of a GPIO, i.e. the value their
|
||||
device will actually receive, no matter what lies between it and the GPIO line.
|
||||
In some cases, it might make sense to control the actual GPIO line value. The
|
||||
following set of calls ignore the active-low property of a GPIO and work on the
|
||||
raw line value:
|
||||
|
||||
int gpiod_get_raw_value(const struct gpio_desc *desc)
|
||||
void gpiod_set_raw_value(struct gpio_desc *desc, int value)
|
||||
int gpiod_get_raw_value_cansleep(const struct gpio_desc *desc)
|
||||
void gpiod_set_raw_value_cansleep(struct gpio_desc *desc, int value)
|
||||
|
||||
The active-low state of a GPIO can also be queried using the following call:
|
||||
|
||||
int gpiod_is_active_low(const struct gpio_desc *desc)
|
||||
|
||||
Note that these functions should only be used with great moderation ; a driver
|
||||
should not have to care about the physical line level.
|
||||
|
||||
GPIOs mapped to IRQs
|
||||
--------------------
|
||||
GPIO lines can quite often be used as IRQs. You can get the IRQ number
|
||||
corresponding to a given GPIO using the following call:
|
||||
|
||||
int gpiod_to_irq(const struct gpio_desc *desc)
|
||||
|
||||
It will return an IRQ number, or an negative errno code if the mapping can't be
|
||||
done (most likely because that particular GPIO cannot be used as IRQ). It is an
|
||||
unchecked error to use a GPIO that wasn't set up as an input using
|
||||
gpiod_direction_input(), or to use an IRQ number that didn't originally come
|
||||
from gpiod_to_irq(). gpiod_to_irq() is not allowed to sleep.
|
||||
|
||||
Non-error values returned from gpiod_to_irq() can be passed to request_irq() or
|
||||
free_irq(). They will often be stored into IRQ resources for platform devices,
|
||||
by the board-specific initialization code. Note that IRQ trigger options are
|
||||
part of the IRQ interface, e.g. IRQF_TRIGGER_FALLING, as are system wakeup
|
||||
capabilities.
|
||||
|
||||
|
||||
Interacting With the Legacy GPIO Subsystem
|
||||
==========================================
|
||||
Many kernel subsystems still handle GPIOs using the legacy integer-based
|
||||
interface. Although it is strongly encouraged to upgrade them to the safer
|
||||
descriptor-based API, the following two functions allow you to convert a GPIO
|
||||
descriptor into the GPIO integer namespace and vice-versa:
|
||||
|
||||
int desc_to_gpio(const struct gpio_desc *desc)
|
||||
struct gpio_desc *gpio_to_desc(unsigned gpio)
|
||||
|
||||
The GPIO number returned by desc_to_gpio() can be safely used as long as the
|
||||
GPIO descriptor has not been freed. All the same, a GPIO number passed to
|
||||
gpio_to_desc() must have been properly acquired, and usage of the returned GPIO
|
||||
descriptor is only possible after the GPIO number has been released.
|
||||
|
||||
Freeing a GPIO obtained by one API with the other API is forbidden and an
|
||||
unchecked error.

GPIO Descriptor Driver Interface
|
||||
================================
|
||||
|
||||
This document serves as a guide for GPIO chip drivers writers. Note that it
|
||||
describes the new descriptor-based interface. For a description of the
|
||||
deprecated integer-based GPIO interface please refer to gpio-legacy.txt.
|
||||
|
||||
Each GPIO controller driver needs to include the following header, which defines
|
||||
the structures used to define a GPIO driver:
|
||||
|
||||
#include <linux/gpio/driver.h>
|
||||
|
||||
|
||||
Internal Representation of GPIOs
|
||||
================================
|
||||
|
||||
Inside a GPIO driver, individual GPIOs are identified by their hardware number,
|
||||
which is a unique number between 0 and n, n being the number of GPIOs managed by
|
||||
the chip. This number is purely internal: the hardware number of a particular
|
||||
GPIO descriptor is never made visible outside of the driver.
|
||||
|
||||
On top of this internal number, each GPIO also need to have a global number in
|
||||
the integer GPIO namespace so that it can be used with the legacy GPIO
|
||||
interface. Each chip must thus have a "base" number (which can be automatically
|
||||
assigned), and for each GPIO the global number will be (base + hardware number).
|
||||
Although the integer representation is considered deprecated, it still has many
|
||||
users and thus needs to be maintained.
|
||||
|
||||
So for example one platform could use numbers 32-159 for GPIOs, with a
|
||||
controller defining 128 GPIOs at a "base" of 32 ; while another platform uses
|
||||
numbers 0..63 with one set of GPIO controllers, 64-79 with another type of GPIO
|
||||
controller, and on one particular board 80-95 with an FPGA. The numbers need not
|
||||
be contiguous; either of those platforms could also use numbers 2000-2063 to
|
||||
identify GPIOs in a bank of I2C GPIO expanders.
|
||||
|
||||
|
||||
Controller Drivers: gpio_chip
|
||||
=============================
|
||||
|
||||
In the gpiolib framework each GPIO controller is packaged as a "struct
|
||||
gpio_chip" (see linux/gpio/driver.h for its complete definition) with members
|
||||
common to each controller of that type:
|
||||
|
||||
- methods to establish GPIO direction
|
||||
- methods used to access GPIO values
|
||||
- method to return the IRQ number associated to a given GPIO
|
||||
- flag saying whether calls to its methods may sleep
|
||||
- optional debugfs dump method (showing extra state like pullup config)
|
||||
- optional base number (will be automatically assigned if omitted)
|
||||
- label for diagnostics and GPIOs mapping using platform data
|
||||
|
||||
The code implementing a gpio_chip should support multiple instances of the
|
||||
controller, possibly using the driver model. That code will configure each
|
||||
gpio_chip and issue gpiochip_add(). Removing a GPIO controller should be rare;
|
||||
use gpiochip_remove() when it is unavoidable.
|
||||
|
||||
Most often a gpio_chip is part of an instance-specific structure with state not
|
||||
exposed by the GPIO interfaces, such as addressing, power management, and more.
|
||||
Chips such as codecs will have complex non-GPIO state.
|
||||
|
||||
Any debugfs dump method should normally ignore signals which haven't been
|
||||
requested as GPIOs. They can use gpiochip_is_requested(), which returns either
|
||||
NULL or the label associated with that GPIO when it was requested.
|
||||
|
||||
Locking IRQ usage
|
||||
-----------------
|
||||
Input GPIOs can be used as IRQ signals. When this happens, a driver is requested
|
||||
to mark the GPIO as being used as an IRQ:
|
||||
|
||||
int gpiod_lock_as_irq(struct gpio_desc *desc)
|
||||
|
||||
This will prevent the use of non-irq related GPIO APIs until the GPIO IRQ lock
|
||||
is released:
|
||||
|
||||
void gpiod_unlock_as_irq(struct gpio_desc *desc)

GPIO Interfaces
|
||||
===============
|
||||
|
||||
The documents in this directory give detailed instructions on how to access
|
||||
GPIOs in drivers, and how to write a driver for a device that provides GPIOs
|
||||
itself.
|
||||
|
||||
Due to the history of GPIO interfaces in the kernel, there are two different
|
||||
ways to obtain and use GPIOs:
|
||||
|
||||
- The descriptor-based interface is the preferred way to manipulate GPIOs,
|
||||
and is described by all the files in this directory excepted gpio-legacy.txt.
|
||||
- The legacy integer-based interface which is considered deprecated (but still
|
||||
usable for compatibility reasons) is documented in gpio-legacy.txt.
|
||||
|
||||
The remainder of this document applies to the new descriptor-based interface.
|
||||
gpio-legacy.txt contains the same information applied to the legacy
|
||||
integer-based interface.
|
||||
|
||||
|
||||
What is a GPIO?
|
||||
===============
|
||||
|
||||
A "General Purpose Input/Output" (GPIO) is a flexible software-controlled
|
||||
digital signal. They are provided from many kinds of chip, and are familiar
|
||||
to Linux developers working with embedded and custom hardware. Each GPIO
|
||||
represents a bit connected to a particular pin, or "ball" on Ball Grid Array
|
||||
(BGA) packages. Board schematics show which external hardware connects to
|
||||
which GPIOs. Drivers can be written generically, so that board setup code
|
||||
passes such pin configuration data to drivers.
|
||||
|
||||
System-on-Chip (SOC) processors heavily rely on GPIOs. In some cases, every
|
||||
non-dedicated pin can be configured as a GPIO; and most chips have at least
|
||||
several dozen of them. Programmable logic devices (like FPGAs) can easily
|
||||
provide GPIOs; multifunction chips like power managers, and audio codecs
|
||||
often have a few such pins to help with pin scarcity on SOCs; and there are
|
||||
also "GPIO Expander" chips that connect using the I2C or SPI serial buses.
|
||||
Most PC southbridges have a few dozen GPIO-capable pins (with only the BIOS
|
||||
firmware knowing how they're used).
|
||||
|
||||
The exact capabilities of GPIOs vary between systems. Common options:
|
||||
|
||||
- Output values are writable (high=1, low=0). Some chips also have
|
||||
options about how that value is driven, so that for example only one
|
||||
value might be driven, supporting "wire-OR" and similar schemes for the
|
||||
other value (notably, "open drain" signaling).
|
||||
|
||||
- Input values are likewise readable (1, 0). Some chips support readback
|
||||
of pins configured as "output", which is very useful in such "wire-OR"
|
||||
cases (to support bidirectional signaling). GPIO controllers may have
|
||||
input de-glitch/debounce logic, sometimes with software controls.
|
||||
|
||||
- Inputs can often be used as IRQ signals, often edge triggered but
|
||||
sometimes level triggered. Such IRQs may be configurable as system
|
||||
wakeup events, to wake the system from a low power state.
|
||||
|
||||
- Usually a GPIO will be configurable as either input or output, as needed
|
||||
by different product boards; single direction ones exist too.
|
||||
|
||||
- Most GPIOs can be accessed while holding spinlocks, but those accessed
|
||||
through a serial bus normally can't. Some systems support both types.
|
||||
|
||||
On a given board each GPIO is used for one specific purpose like monitoring
|
||||
MMC/SD card insertion/removal, detecting card write-protect status, driving
|
||||
a LED, configuring a transceiver, bit-banging a serial bus, poking a hardware
|
||||
watchdog, sensing a switch, and so on.
|
||||
|
||||
|
||||
Common GPIO Properties
|
||||
======================
|
||||
|
||||
These properties are met through all the other documents of the GPIO interface
|
||||
and it is useful to understand them, especially if you need to define GPIO
|
||||
mappings.
|
||||
|
||||
Active-High and Active-Low
|
||||
--------------------------
|
||||
It is natural to assume that a GPIO is "active" when its output signal is 1
|
||||
("high"), and inactive when it is 0 ("low"). However in practice the signal of a
|
||||
GPIO may be inverted before is reaches its destination, or a device could decide
|
||||
to have different conventions about what "active" means. Such decisions should
|
||||
be transparent to device drivers, therefore it is possible to define a GPIO as
|
||||
being either active-high ("1" means "active", the default) or active-low ("0"
|
||||
means "active") so that drivers only need to worry about the logical signal and
|
||||
not about what happens at the line level.
|
||||
|
||||
Open Drain and Open Source
|
||||
--------------------------
|
||||
Sometimes shared signals need to use "open drain" (where only the low signal
|
||||
level is actually driven), or "open source" (where only the high signal level is
|
||||
driven) signaling. That term applies to CMOS transistors; "open collector" is
|
||||
used for TTL. A pullup or pulldown resistor causes the high or low signal level.
|
||||
This is sometimes called a "wire-AND"; or more practically, from the negative
|
||||
logic (low=true) perspective this is a "wire-OR".
|
||||
|
||||
One common example of an open drain signal is a shared active-low IRQ line.
|
||||
Also, bidirectional data bus signals sometimes use open drain signals.
|
||||
|
||||
Some GPIO controllers directly support open drain and open source outputs; many
|
||||
don't. When you need open drain signaling but your hardware doesn't directly
|
||||
support it, there's a common idiom you can use to emulate it with any GPIO pin
|
||||
that can be used as either an input or an output:
|
||||
|
||||
LOW: gpiod_direction_output(gpio, 0) ... this drives the signal and overrides
|
||||
the pullup.
|
||||
|
||||
HIGH: gpiod_direction_input(gpio) ... this turns off the output, so the pullup
|
||||
(or some other device) controls the signal.
|
||||
|
||||
The same logic can be applied to emulate open source signaling, by driving the
|
||||
high signal and configuring the GPIO as input for low. This open drain/open
|
||||
source emulation can be handled transparently by the GPIO framework.
|
||||
|
||||
If you are "driving" the signal high but gpiod_get_value(gpio) reports a low
|
||||
value (after the appropriate rise time passes), you know some other component is
|
||||
driving the shared signal low. That's not necessarily an error. As one common
|
||||
example, that's how I2C clocks are stretched: a slave that needs a slower clock
|
||||
delays the rising edge of SCK, and the I2C master adjusts its signaling rate
|
||||
accordingly.

GPIO Sysfs Interface for Userspace
|
||||
==================================
|
||||
|
||||
Platforms which use the "gpiolib" implementors framework may choose to
|
||||
configure a sysfs user interface to GPIOs. This is different from the
|
||||
debugfs interface, since it provides control over GPIO direction and
|
||||
value instead of just showing a gpio state summary. Plus, it could be
|
||||
present on production systems without debugging support.
|
||||
|
||||
Given appropriate hardware documentation for the system, userspace could
|
||||
know for example that GPIO #23 controls the write protect line used to
|
||||
protect boot loader segments in flash memory. System upgrade procedures
|
||||
may need to temporarily remove that protection, first importing a GPIO,
|
||||
then changing its output state, then updating the code before re-enabling
|
||||
the write protection. In normal use, GPIO #23 would never be touched,
|
||||
and the kernel would have no need to know about it.
|
||||
|
||||
Again depending on appropriate hardware documentation, on some systems
|
||||
userspace GPIO can be used to determine system configuration data that
|
||||
standard kernels won't know about. And for some tasks, simple userspace
|
||||
GPIO drivers could be all that the system really needs.
|
||||
|
||||
Note that standard kernel drivers exist for common "LEDs and Buttons"
|
||||
GPIO tasks: "leds-gpio" and "gpio_keys", respectively. Use those
|
||||
instead of talking directly to the GPIOs; they integrate with kernel
|
||||
frameworks better than your userspace code could.
|
||||
|
||||
|
||||
Paths in Sysfs
|
||||
--------------
|
||||
There are three kinds of entry in /sys/class/gpio:
|
||||
|
||||
- Control interfaces used to get userspace control over GPIOs;
|
||||
|
||||
- GPIOs themselves; and
|
||||
|
||||
- GPIO controllers ("gpio_chip" instances).
|
||||
|
||||
That's in addition to standard files including the "device" symlink.
|
||||
|
||||
The control interfaces are write-only:
|
||||
|
||||
/sys/class/gpio/
|
||||
|
||||
"export" ... Userspace may ask the kernel to export control of
|
||||
a GPIO to userspace by writing its number to this file.
|
||||
|
||||
Example: "echo 19 > export" will create a "gpio19" node
|
||||
for GPIO #19, if that's not requested by kernel code.
|
||||
|
||||
"unexport" ... Reverses the effect of exporting to userspace.
|
||||
|
||||
Example: "echo 19 > unexport" will remove a "gpio19"
|
||||
node exported using the "export" file.
|
||||
|
||||
GPIO signals have paths like /sys/class/gpio/gpio42/ (for GPIO #42)
|
||||
and have the following read/write attributes:
|
||||
|
||||
/sys/class/gpio/gpioN/
|
||||
|
||||
"direction" ... reads as either "in" or "out". This value may
|
||||
normally be written. Writing as "out" defaults to
|
||||
initializing the value as low. To ensure glitch free
|
||||
operation, values "low" and "high" may be written to
|
||||
configure the GPIO as an output with that initial value.
|
||||
|
||||
Note that this attribute *will not exist* if the kernel
|
||||
doesn't support changing the direction of a GPIO, or
|
||||
it was exported by kernel code that didn't explicitly
|
||||
allow userspace to reconfigure this GPIO's direction.
|
||||
|
||||
"value" ... reads as either 0 (low) or 1 (high). If the GPIO
|
||||
is configured as an output, this value may be written;
|
||||
any nonzero value is treated as high.
|
||||
|
||||
If the pin can be configured as interrupt-generating interrupt
|
||||
and if it has been configured to generate interrupts (see the
|
||||
description of "edge"), you can poll(2) on that file and
|
||||
poll(2) will return whenever the interrupt was triggered. If
|
||||
you use poll(2), set the events POLLPRI and POLLERR. If you
|
||||
use select(2), set the file descriptor in exceptfds. After
|
||||
poll(2) returns, either lseek(2) to the beginning of the sysfs
|
||||
file and read the new value or close the file and re-open it
|
||||
to read the value.
|
||||
|
||||
"edge" ... reads as either "none", "rising", "falling", or
|
||||
"both". Write these strings to select the signal edge(s)
|
||||
that will make poll(2) on the "value" file return.
|
||||
|
||||
This file exists only if the pin can be configured as an
|
||||
interrupt generating input pin.
|
||||
|
||||
"active_low" ... reads as either 0 (false) or 1 (true). Write
|
||||
any nonzero value to invert the value attribute both
|
||||
for reading and writing. Existing and subsequent
|
||||
poll(2) support configuration via the edge attribute
|
||||
for "rising" and "falling" edges will follow this
|
||||
setting.
|
||||
|
||||
GPIO controllers have paths like /sys/class/gpio/gpiochip42/ (for the
|
||||
controller implementing GPIOs starting at #42) and have the following
|
||||
read-only attributes:
|
||||
|
||||
/sys/class/gpio/gpiochipN/
|
||||
|
||||
"base" ... same as N, the first GPIO managed by this chip
|
||||
|
||||
"label" ... provided for diagnostics (not always unique)
|
||||
|
||||
"ngpio" ... how many GPIOs this manges (N to N + ngpio - 1)
|
||||
|
||||
Board documentation should in most cases cover what GPIOs are used for
|
||||
what purposes. However, those numbers are not always stable; GPIOs on
|
||||
a daughtercard might be different depending on the base board being used,
|
||||
or other cards in the stack. In such cases, you may need to use the
|
||||
gpiochip nodes (possibly in conjunction with schematics) to determine
|
||||
the correct GPIO number to use for a given signal.
|
||||
|
||||
|
||||
Exporting from Kernel code
|
||||
--------------------------
|
||||
Kernel code can explicitly manage exports of GPIOs which have already been
|
||||
requested using gpio_request():
|
||||
|
||||
/* export the GPIO to userspace */
|
||||
int gpiod_export(struct gpio_desc *desc, bool direction_may_change);
|
||||
|
||||
/* reverse gpio_export() */
|
||||
void gpiod_unexport(struct gpio_desc *desc);
|
||||
|
||||
/* create a sysfs link to an exported GPIO node */
|
||||
int gpiod_export_link(struct device *dev, const char *name,
|
||||
struct gpio_desc *desc);
|
||||
|
||||
/* change the polarity of a GPIO node in sysfs */
|
||||
int gpiod_sysfs_set_active_low(struct gpio_desc *desc, int value);
|
||||
|
||||
After a kernel driver requests a GPIO, it may only be made available in
|
||||
the sysfs interface by gpiod_export(). The driver can control whether the
|
||||
signal direction may change. This helps drivers prevent userspace code
|
||||
from accidentally clobbering important system state.
|
||||
|
||||
This explicit exporting can help with debugging (by making some kinds
|
||||
of experiments easier), or can provide an always-there interface that's
|
||||
suitable for documenting as part of a board support package.
|
||||
|
||||
After the GPIO has been exported, gpiod_export_link() allows creating
|
||||
symlinks from elsewhere in sysfs to the GPIO sysfs node. Drivers can
|
||||
use this to provide the interface under their own device in sysfs with
|
||||
a descriptive name.
|
||||
|
||||
Drivers can use gpiod_sysfs_set_active_low() to hide GPIO line polarity
|
||||
differences between boards from user space. Polarity change can be done both
|
||||
before and after gpiod_export(), and previously enabled poll(2) support for
|
||||
either rising or falling edge will be reconfigured to follow this setting.
