Merge tag 'pinctrl-v6.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl 

Pull pin control updates from Linus Walleij:
 "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;

                        interrupt-controller;

                        st,supports-sleepmode;

                        gpio-bank = <1>;

                };

title: Nomadik GPIO controller



description:

  The Nomadik GPIO driver handles Nomadik SoC GPIO blocks. This block has also

  been called ST STA2X11. On the Nomadik platform, this driver is intertwined

  with pinctrl-nomadik.
