From b5a6c94a0380071600dc5b8be1853164f62af146 Mon Sep 17 00:00:00 2001 From: Ken Ma Date: Thu, 22 Jun 2017 17:13:35 +0800 Subject: [PATCH] pinctrl: a3700: Fix uart2 group selection register mask If north bridge selection register bit1 is clear, pins [10:8] are for SDIO0 Resetn, Wakeup, and PDN while if bit1 is set, pins [10:8]are for GPIO; when bit1 is clear, pin 9 and pin 10 can be used for uart2 RTSn and CTSn, so bit1 should be added to uart2 group and it must be set for both "gpio" and "uart" functions of uart2 group.
