Subject: [PATCH] ARM: i.MX: rdu2: Make use of imx_setup_pad()
Date: Tue, 19 Jun 2018 18:21:54 -0700 [thread overview]
Message-ID: <20180620012154.21183-1-andrew.smirnov@gmail.com> (raw)
While at it, also remove pinux configuration for RX pin (completely
unused) and fix strange setup_uart()'s indentation.
