Subject: [PATCH 07/13] arm64: dts: rockchip: move px30-evb console output to uart 5
Date: Tue, 17 Sep 2019 10:26:53 +0200 [thread overview]
Message-ID: <20190917082659.25549-7-heiko@sntech.de> (raw)
In-Reply-To: <20190917082659.25549-1-heiko@sntech.de>
The px30-evb exposes uart2 through a uart-to-usb converter on the board
but these pins are shared with the sdmmc controller. With both activated
this results in a race condition depending in the probe order.
Whichever of the two probes first will break the other peripheral.
The px30-evb also exposes uart5 through pin its pin headers, so it's way
saner to use these pins for serial output and keep the sdmmc working in
all cases.
