Subject: [PATCH] arm64: dts: draak: Add serial console pins
Date: Mon, 28 Aug 2017 11:26:10 +0200 [thread overview]
Message-ID: <1503912370-20180-1-git-send-email-geert+renesas@glider.be> (raw)
Add pin control for SCIF2.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
---
To be applied after v4.14-rc1, when commit 794a6711764658a1 ("pinctrl:
sh-pfc: Initial R8A77995 PFC support") has hit mainline.
Else the serial console will fail, reporting (on earlycon):
sh-sci e6e88000.serial: could not find pctldev for node /soc/pin-controller at e6060000/scif2, deferring probe
