[PATCH 7/7] drm/msm/dpu: support setting the TE source

2024-05-20 Thread Dmitry Baryshkov
Make the DPU driver use the TE source specified in the DT. If none is specified, the driver defaults to the first GPIO (mdp_vsync0). Signed-off-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 44 - 1 file changed, 43 insertions(+), 1 deletion(-)

Allow board's device tree to specify the vsync source (aka TE source). If the property is omitted, the display controller driver will use the default setting. Signed-off-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/dsi/dsi.h | 1 + drivers/gpu/drm/msm/dsi/dsi_host.c| 11 +++

[PATCH 5/7] drm/msm/dpu: rework vsync_source handling

2024-05-20 Thread Dmitry Baryshkov
The struct msm_display_info has is_te_using_watchdog_timer field which is neither used anywhere nor is flexible enough to specify different sources. Replace it with the field specifying the vsync source using enum dpu_vsync_source. Signed-off-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/disp/dpu

[PATCH 1/7] dt-bindings: display/msm/dsi: allow specifying TE source

2024-05-20 Thread Dmitry Baryshkov
Command mode panels provide TE signal back to the DSI host to signal that the frame display has completed and update of the image will not cause tearing. Usually it is connected to the first GPIO with the mdp_vsync function, which is the default. In such case the property can be skipped. Signed-of

[PATCH 0/7] drm/msm/dpu: handle non-default TE source pins

2024-05-20 Thread Dmitry Baryshkov
Command-mode DSI panels need to signal the display controlller when vsync happens, so that the device can start sending the next frame. Some devices (Google Pixel 3) use a non-default pin, so additional configuration is required. Add a way to specify this information in DT and handle it in the DSI
