Pin control changes for the v6.9 kernel cycle:
No core changes this time around.
New drivers:
- New driver for Renesas R8A779H0 also known as R-Car V4M.
- New driver for the Awinic AW9523/B I2C GPIO expander.
I found this living out-of-tree in OpenWrt as an upstream
attempt had stalled on the finishing line, so I picked it
up and finished the job.
Improvements:
- The Nomadik pin control driver was for years re-used out of
tree for the ST STA chips, and now the IP was re-used in a
MIPS automotive SoC called MobilEyeq5, so it has been split
in pin control and GPIO drivers so the latter can be reused
by MobilEyeq5. (Along with a long list of cleanups.)
- A lot of overall cleanup and tidying up.

Nomadik GPIO controller
|
||||
|
||||
Required properties:
|
||||
- compatible : Should be "st,nomadik-gpio".
|
||||
- reg : Physical base address and length of the controller's registers.
|
||||
- interrupts : The interrupt outputs from the controller.
|
||||
- #gpio-cells : Should be two:
|
||||
The first cell is the pin number.
|
||||
The second cell is used to specify optional parameters:
|
||||
- bits[3:0] trigger type and level flags:
|
||||
1 = low-to-high edge triggered.
|
||||
2 = high-to-low edge triggered.
|
||||
4 = active high level-sensitive.
|
||||
8 = active low level-sensitive.
|
||||
- gpio-controller : Marks the device node as a GPIO controller.
|
||||
- interrupt-controller : Marks the device node as an interrupt controller.
|
||||
- gpio-bank : Specifies which bank a controller owns.
|
||||
- st,supports-sleepmode : Specifies whether controller can sleep or not
|
||||
|
||||
Example:
|
||||
|
||||
gpio1: gpio@8012e080 {
|
||||
compatible = "st,nomadik-gpio";
|
||||
reg = <0x8012e080 0x80>;
|
||||
interrupts = <0 120 0x4>;
|
||||
#gpio-cells = <2>;
|
||||
gpio-controller;
|
||||

|
||||
st,supports-sleepmode;

||||

description: >
|
||||
The EyeQ5 pin controller handles the two pin banks of the system. It belongs
|
||||
to a system-controller block called OLB.
|
||||
|
||||
Pin control is about bias (pull-down, pull-up), drive strength and muxing. Pin
|
||||
muxing supports two functions for each pin: first is GPIO, second is
|
||||
pin-dependent.
|
||||
|
||||
Pins and groups are bijective.
