2021-12-17gpio: Setup parent device and get rid of unnecessary of_node assignmentAndy Shevchenko1-1/+1
Some of the drivers do not set parent device. This may lead to obstacles during debugging or understanding the device relations from the Linux point of view. Assign parent device for GPIO chips created by these drivers. While at it, let GPIO library to assign of_node from the parent device.

2018-10-10GPIO: add single-register GPIO via CREG driverEugeniy Paltsev1-0/+191
Add single-register MMIO GPIO driver for complex cases where only several fields in register belong to GPIO lines and each GPIO line owns a field with different length and on/off value. Such CREG GPIOs are used in Synopsys AXS10x and HSDK boards. Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
