This series of patches converts rsk7203 to use static device properties
for its devices, including gpio-keys and gpio-leds, and removing
dependency on legacy gpio API (in favor of gpiod API).
To configure pin functions the board is switched to use gpio-hogs, as
doing full conversion to pinmux is too challenging without access to
hardware.
v2:
- Added a patch to isolate the function gpiochip from the parent fwnode
to prevent ambiguous property lookups
- Added a patch attaching a software node to the main PFC gpiochip device
- Adjusted the board setup to use the PFC's software node for LEDs and
GPIO keys instead of creating a standalone node
- Added support to sh-pfc for configuring the secondary "function"
gpiochip via a "functions" child software node.
- Converted board pin configuration from legacy gpio_request() to GPIO
hogs, using postcore_initcall to ensure nodes are available during
driver probe.
