Since Meson G12A SoC, Introduce new ao registers AO_RTI_PULL_UP_EN_REG
and AO_GPIO_O.
These bits of controlling output level are remapped to the new register
AO_GPIO_O, and the AO_GPIO_O_EN_N support only controlling output enable.
These bits of controlling pull enable are remapped to the new register
AO_RTI_PULL_UP_EN_REG, and the AO_RTI_PULL_UP_REG support only controlling
pull type(up/down).
The new layout of ao gpio/pull registers is as follows:
- AO_GPIO_O_EN_N [offset: 0x9 << 2]
- AO_GPIO_I [offset: 0xa << 2]
- AO_RTI_PULL_UP_REG [offset: 0xb << 2]
- AO_RTI_PULL_UP_EN_REG [offset: 0xc << 2]
- AO_GPIO_O [offset: 0xd << 2]
From above, we can see ao GPIO registers region has been separated by the
ao pull registers. In order to ensure the continuity of the region on
software, the ao GPIO and ao pull registers use the same base address, but
can be identified by the offset.

Keeping the irq_chip definition static shares it with multiple instances
of the mcp23s08 gpiochip in the system. This is bad and now we get this
warning from gpiolib core:
"detected irqchip that is shared with multiple gpiochips: please fix the

Hence, move the irq_chip definition from being driver static into the

Armada 3700 PCIe IP relies on the pinctrl IP managed by this
driver. For reasons related to the PCI core's organization when
suspending/resuming, PCI host controller drivers must reconfigure
their register at suspend_noirq()/resume_noirq() which happens after
suspend()/suspend_late() and before resume_early()/resume().
In the current state, after resuming from a suspend to RAM cycle the
PCIe IP is reconfigured before the pinctrl one which produces an
interrupt storm. The solution to support PCIe resume operation is to
change the "priority" of this pinctrl driver PM callbacks to
"_noirq()".

The probing of this driver calls platform_irq_count, which will
setup all of the IRQs that are configured in device tree. In
preparation for converting this driver to be a hierarchical IRQ
chip, hardcode the IRQ count based on the hardware type so that all
the IRQs are not configured immediately and are configured on an
as-needed basis later in the boot process. This change will also
allow for the removal of the interrupts property later in this
patch series once the hierarchical IRQ chip support is in.
This patch also removes the generic qcom,spmi-gpio OF match since we
don't know the number of pins. All of the existing upstream bindings
already include the more-specific binding.

When declaring the HSPI RX1_B and TX1_B pins, two mistakes were made:
- the rows and columns in the BGA pin matrix, from which the pin
numbers are derived, were exchanged,
- it was not taken into account that pin row labelling skips
characters I, O, Q, and S.
Fix the order, and the corresponding pin names.
Notes:
- The actual values of the pin numbers don't really matter (they just
have to be unique), so the wrong order didn't have any impact,
- Changing the names of the pins is user-visible, but there are no
users in (upstream) DTS files.

On most newer Allwinner SoCs, there are two pinctrl devices, the PIO and
R_PIO. PIO covers pin-banks PA to PI (PJ and PK have not been seen),
while R_PIO covers PL to PN. The regulator array only has space for 12
entries, which was designed to cover PA to PL. On the A80, the pin banks
go up to PN, which would be the 14th entry in the regulator array.
However since the driver only needs to track regulators for its own pin
banks, the array only needs to have 9 entries, and also take in to
account the value of pin_base, such that the regulator for the first
pin-bank of the pinctrl device, be it "PA" or "PL" uses the first entry
of the array.
Base the regulator array index on pin_base, such that "PA" for PIO and
"PL" for R_PIO both take the first element within their respective
device's regulator array.
Also decrease the size of the regulator array to 9, just enough to cover
"PA" to "PI".

The new per-pin-bank regulator handling code in the sunxi pinctrl driver
has mismatched conditions for enabling and disabling the regulator: it
is enabled each time a pin is requested, but only disabled when the
pin-bank's reference count reaches zero.
Since we are doing reference counting already, there's no need to enable
the regulator each time a pin is requested. Instead we can just do it
for the first requested pin of each pin-bank. Thus we can reverse the
test and bail out early if it's not the first occurrence.

Merge tag 'pinctrl-v4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"We have no core changes but lots of incremental development in drivers
all over the place: Renesas, NXP, Mediatek and Actions Semiconductor
keep churning out new SoCs.
I have some subtree maintainers for Renesas and Intel helping out to
keep down the load, it's been working smoothly (Samsung also have a
subtree but it was not used this cycle.)
New drivers:
- NXP (ex Freescale) i.MX 8 QXP SoC driver.
- Mediatek MT6797 SoC driver.
- Mediatek MT7629 SoC driver.
- Actions Semiconductor S700 SoC driver.
- Renesas RZ/A2 SoC driver.
- Allwinner sunxi suniv F1C100 SoC driver.
- Qualcomm PMS405 PMIC driver.
- Microsemi Ocelot Jaguar2 SoC driver.
Improvements:
- Some RT improvements (using raw spinlocks where appropriate).
- A lot of new pin sets on the Renesas PFC pin controllers.
- GPIO hogs now work on the Qualcomm SPMI/SSBI pin controller GPIO
chips, and Xway.
- Major modernization of the Intel pin control drivers.
- STM32 pin control driver will now synchronize usage of pins with
another CPU using a hardware spinlock"

pinmux_cfg_reg.var_field_width[] is actually a variable-length array,
terminated by a zero, and counting at most r_width entries.
Usually the number of entries is much smaller than r_width, so the
ability to catch bugs at compile time through an "excess elements in
array initializer" warning is fairly limited.
Hence make the array variable-length, decreasing kernel size slightly.

The debug code in sh_pfc_write_config_reg() prints the width of the
field being modified.
However, registers with a variable-width field layout are identified by
pinmux_cfg_reg.field_width being zero, hence zeroes are printed instead
of the actual field widths.
Fix this by printing the Hamming weight of the field mask instead, which
is correct for both fixed-width and variable-width fields.

The Allwinner SoCs have on most of their GPIO banks a regulator input.
This issue was mainly ignored so far because either the regulator was a
static regulator that would be providing power anyway, or the bank was used
for a feature unsupported so far (CSI). For the odd cases, enabling it in
the bootloader was the preferred option.
However, now that we are starting to support those features, and that we
can't really rely on the bootloader for this, we need to model those
regulators as such in the DT.
This is slightly more complicated than what it looks like, since some
regulators will be tied to the PMIC, and in order to have access to the
PMIC bus, you need to mux its pins, which will need the pinctrl driver,
that needs the regulator driver to be registered. And this is how you get a
circular dependency.
In practice however, the hardware cannot fall into this case since it would
result in a completely unusable bus. In order to avoid that circular
dependency, we can thus get and enable the regulators at pin_request time.
We'll then need to account for the references of all the pins of a
particular branch to know when to put the reference, but it works pretty
nicely once implemented.

intel-pinctrl for v4.21-1
Switch to generic ->probe() callbacks.
Simplify getting .driver_data.
Code formatting fixes and headers clean up.
Special case is the driver for Intel Cherryview SoC, where GPIO enabling bit
was mistakenly cleared when pin gets freed. It's fixed now.
The below commit went to v4.20-rc3, that's why duplication.

Pin PH11 is used on various A83T board to detect a change in the OTG
port's ID pin, as in when an OTG host cable is plugged in.
The incorrect offset meant the gpiochip/irqchip was activating the wrong

Clearing the GPIO_EN bit from chv_gpio_disable_free is a bad idea and
pinctrl-cherryview.c is the only Intel pinctrl driver doing something
like this.
Clearing the GPIO_EN bit means that if the pin was an output it is now
effectively floating. The datasheet is not clear what happens to pull ups /
downs in this case, but from testing it looks like these are disabled too,
also floating input pins.
One example where this is causing issues is the soc_button_array input
driver, this parses ACPI tables to create 2 platform devices for the
gpio_keys input driver. The list of GPIOs is passed through struct
gpio_keys_platform_data which uses gpio numbers rather then gpio_desc
pointers.
The buttons handled by this drivers short the pin to ground when pressed
and the volume buttons rely on the SoC's internal pull-up to pull the
pin high when the button is not pressed.
To get the gpio number, the soc_button_array code calls gpiod_get_index
followed by a desc_to_gpio call and then gpiod_put on the gpio_desc.
This last call causes chv_gpio_disable_free to clear the GPIO_EN bit.
When the gpio_keys driver then loads next it gets the gpio_desc again
causing the GPIO_EN bit to be set again and immediately reads the GPIO
value which for the volume buttons reads 0 at this time, causing a spurious
press of the volume buttons to get reported.
Putting a small delay between the gpio_desc request and the read fixes
this, I assume that this is caused by the pull-up being temporarily
disabled while the GPIO_EN bit is cleared as the powerbutton which also
has its GPIO_EN bit cleared does not have this problem.
The soc_button_array code is not the only code temporarily requesting GPIOs
the DWC3 PCI code also does this, to set the enable and reset GPIOs for the
external phy, so that the code instantiating the ULPI phy can read the
vendor and product ID registers from the phy. These GPIOs are released
after this so that the PHY driver can claim and use them when it loads.
Another example of temporary GPIO usage would be a user-space set_gpio
utility using the userspace ioctls to set a GPIO as output value 0 or 1,
having the GPIO revert to floating as soon as this utility exits would
certainly be unexpected behavior.
One argument in favor of clearing the GPIO_EN bit is if the GPIO is going
to be muxed to another function after being released, but in that case
chv_pinmux_set_mux() already clears it.
TL;DR: Clearing the GPIO_EN bit from is a bad idea, this commit therefor
removes the clearing from chv_gpio_disable_free(), replacing it with code
to clear the interrupt-trigger condition so that the GPIO stops generating
interrupts when released, as pinctrl-baytrail.c does.
Note this commit adds a !chv_pad_locked() condition to the trigger clearing
call, which the original GPIO_EN clearing code was missing.

We just changed the code so we apply bias disable on the correct
register but forgot to align the register calculation. The result
is that we apply the change on the correct register, but possibly
at the incorrect offset/bit
This went undetected because offsets tends to be the same between
REG_PULL and REG_PULLEN for a given pin the EE controller. This
is not true for the AO controller.
