Subject[PATCH 0/2] gpio: mmio: introduce BGPIOF_NO_SET_ON_INPUT
Date
Currently gpio-hog doesn't work on gpio-mt7621 driver. On further
debugging, I noticed that set/clear register on this controller
only works on output pins. We need to setup pin direction before
writing values in bgpio_dir_out for a correct gpio-hog behavior.
This patchset introduces a new flag BGPIOF_NO_SET_ON_INPUT for
these kind of controller and set this flag for gpio-mt7621.
