Qualcomm MSM8996 TLMM block
|
||||
|
||||
This binding describes the Top Level Mode Multiplexer block found in the
|
||||
MSM8996 platform.
|
||||
|
||||

|
||||
Usage: required
|
||||

||||

|
||||
Value type: <prop-encoded-array>
|
||||
Definition: the base address and size of the TLMM register space.
|
||||
|
||||
- interrupts:
|
||||
Usage: required
|
||||
Value type: <prop-encoded-array>

||||
- #interrupt-cells:
|
||||

|
||||

|
||||
in <dt-bindings/interrupt-controller/irq.h>
|
||||
|
||||
- gpio-controller:
|
||||
Usage: required
|

|
||||
|
||||
Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
|
||||
a general description of GPIO and interrupt bindings.
|
||||
|
||||
Please refer to pinctrl-bindings.txt in this directory for details of the
|
||||
common pinctrl bindings used by client devices, including the meaning of the
|
||||
phrase "pin configuration node".
|
||||
|
||||
The pin configuration nodes act as a container for an arbitrary number of
|
||||
subnodes. Each of these subnodes represents some desired configuration for a
|
||||
pin, a group, or a list of pins or groups. This configuration can include the
|
||||
mux function to select on those pin(s)/group(s), and various pin configuration
|
||||
parameters, such as pull-up, drive strength, etc.
|
||||
|
||||
|
||||
PIN CONFIGURATION NODES:
|
||||
|
||||
The name of each subnode is not important; all subnodes should be enumerated
|
||||
and processed purely based on their content.
|
||||
|
||||
Each subnode only affects those parameters that are explicitly listed. In
|
||||
other words, a subnode that lists a mux function but no pin configuration
|
||||
parameters implies no information about any pin configuration parameters.
|
||||
Similarly, a pin subnode that describes a pullup parameter implies no
|
||||
information about e.g. the mux function.
|
||||
|
||||
|
||||
The following generic properties as defined in pinctrl-bindings.txt are valid
|
||||
to specify in a pin configuration subnode:
|
||||
|
||||
- pins:
|
||||
Usage: required
|
||||
Value type: <string-array>
|
||||
Definition: List of gpio pins affected by the properties specified in
|
||||
this subnode.
|
||||
|
||||
Valid pins are:
|
||||
gpio0-gpio149
|
||||
Supports mux, bias and drive-strength
|
||||
|
||||
sdc1_clk, sdc1_cmd, sdc1_data sdc2_clk, sdc2_cmd,
|
||||
sdc2_data sdc1_rclk
|
||||
Supports bias and drive-strength
|
||||
|
||||
- function:
|
||||
Usage: required
|
||||
Value type: <string>
|
||||
Definition: Specify the alternative function to be configured for the
|
||||
specified pins. Functions are only valid for gpio pins.
