Subject: [PATCH 18/62] gpio: gpio-lp873x: Use new GPIO_LINE_DIRECTION
Date: Tue, 5 Nov 2019 12:18:20 +0200 [thread overview]
Message-ID: <5f6487bef761bdfe1e243ce54eb9ffa5ce2c1351.1572945776.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1572945776.git.matti.vaittinen@fi.rohmeurope.com>
It's hard for occasional GPIO code reader/writer to know if values 0/1
equal to IN or OUT. Use defined GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT to help them out.
