Subject: [PATCH] arm64: dts: rockchip: fix cts, rts pin assign of UART3 for rk3399
Date: Sun, 7 Apr 2019 00:35:57 +0900 [thread overview]
Message-ID: <20190406153557.25930-1-katsuhiro@katsuster.net> (raw)
This patch fixes pin assign of cts and rts signal of UART3.
Currently GPIO3_C2 and C3 pins are assigned but TRM says that
GPIO3_C0 and C1 are correct.
Refer:
RK3399 TRM v1.4 - Table 19-1 UART Interface Description
