Subject: [PATCH 11/12] ARM: dts: mmp3-dell-ariel: Replace SSP2 with spi-gpio
Date:   Thu, 21 Jan 2021 04:41:29 +0100

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.
