Subject: [PATCH 11/12] ARM: dts: mmp3-dell-ariel: Replace SSP2 with spi-gpio
Date: Thu, 21 Jan 2021 04:41:29 +0100	[thread overview]
Message-ID: <20210121034130.1381872-12-lkundrak@v3.sk> (raw)
In-Reply-To: <20210121034130.1381872-1-lkundrak@v3.sk>

The firmware leaves the pins in GPIO mode. Until we have a proper pinmux
driver hooked on we just need to bitbang SPI. No big deal, this is just
used for the power button and performance is not important.
