H A D | rockchip_drm_drv.h | diff cf544c6a885c52d79e4d8bf139fb8cb63a878512 Fri Apr 22 09:28:20 CEST 2022 Sascha Hauer <s.hauer@pengutronix.de> drm/rockchip: Add crtc_endpoint_id to rockchip_encoder
The VOP2 has an interface mux which decides to which encoder(s) a CRTC is routed to. The encoders and CRTCs are connected via of_graphs in the device tree. When given an encoder the VOP2 driver needs to know to which internal register setting this encoder matches. For this the VOP2 binding offers different endpoints, one for each possible encoder. The endpoint ids of these endpoints are used as a key from an encoders device tree description to the internal register setting.
This patch adds the key aka endpoint id to struct rockchip_encoder plus a function to read the endpoint id starting from the encoders device node.
