[PATCH v2 4/7] staging: mt7621-gpio: implement '.irq_[request|release]_resources' functions

When implementing custom irqchips it is important to also implement .irq_request_resources() and .irq_release_resources() and make sure these call gpiochip_[un]lock_as_irq(). Add those two for this driver. Also store struct device pointer in global state structure to be able to use 'dev_err' with

[PATCH v2 6/7] staging: mt7621-gpio: add kerneldoc for state data containers

This commit adds kerneldoc for the two data containers in order to better understanding of its existence. Signed-off-by: Sergio Paracuellos --- drivers/staging/mt7621-gpio/gpio-mt7621.c | 18 ++ 1 file changed, 18 insertions(+) diff --git

[PATCH v2 3/7] staging: mt7621-gpio: make use of 'builtin_platform_driver'

[PATCH v2 1/7] staging: mt7621-gpio: make use 'bgpio_init' from GPIO_GENERIC

Gpio complexity is just masking the fact that offset is always 0..n and writes to bits 0..n of some memory address. Because of this whole thing can just me converted to use GPIO_GENERIC and avoid duplications of a lot of driver custom functions. So use bgpio_init instead of custom code adding
