Subject: [PATCH v5 14/17] arm64: meson: g12-common: add the MIPI DSI nodes
Date: Tue, 30 May 2023 09:38:15 +0200	[thread overview]
Message-ID: <20230512-amlogic-v6-4-upstream-dsi-ccf-vim3-v5-14-56eb7a4d5b8e@linaro.org> (raw)
In-Reply-To: <20230512-amlogic-v6-4-upstream-dsi-ccf-vim3-v5-0-56eb7a4d5b8e@linaro.org>

Add the MIPI DSI Analog & Digital PHY nodes and the DSI control
nodes with proper port endpoint to the VPU.
