Subject: [PATCH 1/3] arm64: dts: rockchip: rk3328-roc-cc: Set dr_mode to "host" for OTG
Date: Thu, 26 Nov 2020 15:33:34 +0800
Message-ID: <20201126073336.30794-2-wens@kernel.org> (raw)
In-Reply-To: <20201126073336.30794-1-wens@kernel.org>

From: Chen-Yu Tsai <wens@csie.org>

The board has a standard USB A female port connected to the USB OTG
controller's data pins. Set dr_mode in the OTG controller node to
indicate this usage, instead of having the implementation guess.

Fixes: 2171f4fdac06 ("arm64: dts: rockchip: add roc-rk3328-cc board")
