Subject: [PATCH 08/62] gpio: gpio-bcm-kona: Use new GPIO_LINE_DIRECTION
Message-ID: <47840e5f6268d598ed511dcdefcfeb9435109c21.1572945719.git.matti.vaittinen@fi.rohmeurope.com>

Precedence: bulk

t'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.
