Subject: [PATCH 2/2] gpio: mt7621: add BGPIOF_NO_SET_ON_INPUT flag
Date: Sun, 15 Mar 2020 20:13:38 +0800	[thread overview]
Message-ID: <20200315121338.251362-3-gch981213@gmail.com> (raw)
In-Reply-To: <20200315121338.251362-1-gch981213@gmail.com>

DSET/DCLR registers only works on output pins. Add corresponding
BGPIOF_NO_SET_ON_INPUT flag to bgpio_init call to fix direction_out
behavior.
