Subject: [PATCH] ARM: dts: switch atmel mxt reset gpio to active low
Date: Fri, 20 Nov 2020 17:00:54 +0100 [thread overview]
Message-ID: <20201120160053.18942-1-martin.juecker@gmail.com> (raw)
The reset gpio logic of the atmel driver was changed to be active low at
around the same time this device tree was accepted into the kernel.
Adjust the configuration so that the touchscreen is in a usable state.
