Subject: [PATCH 4.19 039/106] pinctrl: meson-gxbb: Fix wrong pinning definition for uart_c

From: Otto Meier <gf435@....net>

[ Upstream commit cb0438e4436085d89706b5ccfce4d5da531253de ]

Hi i tried to use the uart_C of the the odroid-c2.

I enabled it in the dts file. During boot it crashed when the
the sdcard slot is addressed.

After long search in the net i found this:

https://forum.odroid.com/viewtopic.php?f=139&t=25371&p=194370&hilit=uart_C#p177856

After changing the pin definitions accordingly erverything works.
Uart_c is functioning and sdcard ist working.
