Subject: [PATCH v2 1/2] dt-bindings: phy: add yaml binding for rockchip-inno-csi-dphy
Date: Thu, 10 Jun 2021 23:29:34 +0200 [thread overview]
Message-ID: <20210610212935.3520341-2-heiko@sntech.de> (raw)
In-Reply-To: <20210610212935.3520341-1-heiko@sntech.de>
From: Heiko Stuebner <heiko.stuebner@theobroma-systems.com>
Some Rockchip SoCs like the rk3368, rk3326, px30 use a CSI dphy
based on an Innosilicon IP. Add a binding for them.
