OK maybe it's not easy to find. If you look into:
arch/arm/mach-ux500/board-mop500-pins.c
you find our work in progress. Note that this is not (yet)
using device tree. (We want to migrate all our pinctrl
stuff first, then do DT.)
So for example this macro:
#define DB8500_PIN(pin,conf,dev) \
PIN_MAP_CONFIGS_PIN_DEFAULT(dev, "pinctrl-db8500", pin, conf)
Will define a config for the "default" mode for a certain
pin.
This:
#define DB8500_PIN_SLEEP(pin, conf, dev) \
PIN_MAP_CONFIGS_PIN(dev, PINCTRL_STATE_SLEEP, "pinctrl-db8500", \
pin, conf)
Will mutatis mutandis define a "sleep" mode for a pin.
Sorry for the macros. We'll get rid of them in the DT.
(Now that Stephen has patched in preprocessing it will
even look good.)
Yours,
Linus Walleij
