From 5f441a7b3db705cd1dd546f6e623586801da6c07 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Mon, 5 Aug 2019 09:45:09 +0200 Subject: [PATCH] rockchip: px30: add uart5 as option for serial output The px30 mini-evb can use either uart2 (muxed with the sd-card pins) or uart5 via its pin header for serial output. Uart5 is especially useful when needing to boot from the sd-card, where uart2 obviously is not useable. So add the uart5 constants and it as uart option for the serial-param handler.
