Changes in v1: - add connector type in the disp_info (Dmitry) - add helper functions to know encoder type - update commit text reflecting the change Changes in v2: - avoid hardcode of connector type for DSI as it may not be true (Dmitry) - get the HPD information from encoder bridge Changes in v3: - use connector type instead of bridge ops in determining connector (Dmitry) Changes in v4: - get type from the drm connector rather from bridge connector (Dmitry) Signed-off-by: Kalyan Thota Reviewed-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 26 ++++++++++++++++++++++++++ drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.h | 6 ++++++ 2 files changed, 32 insertions(+) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c index 9c6817b..96db7fb 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c @@ -217,6 +217,32 @@ static u32 dither_matrix[DITHER_MATRIX_SZ] = { 15, 7, 13, 5, 3, 11, 1, 9, 12, 4, 14, 6, 0, 8, 2, 10 }; +bool dpu_encoder_is_builtin(struct drm_encoder *encoder) +{ + struct drm_connector *connector; + struct drm_connector_list_iter conn_iter; + struct drm_device *dev = encoder->dev; + int type = 0; + + drm_connector_list_iter_begin(dev, &conn_iter); + drm_for_each_connector_iter(connector, &conn_iter) { + if (drm_connector_has_possible_encoder(connector, encoder)) { + type = connector->connector_type; + break; + } + } + drm_connector_list_iter_end(&conn_iter); + + switch (type) { + case DRM_MODE_CONNECTOR_LVDS: + case DRM_MODE_CONNECTOR_eDP: + case DRM_MODE_CONNECTOR_DSI: + case DRM_MODE_CONNECTOR_DPI: + return true; + default: + return false; + } +} bool dpu_encoder_is_widebus_enabled(const struct drm_encoder *drm_enc) { diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.h b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.h index 9e7236e..7f3d823 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.h +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.h @@ -224,4 +224,10 @@ void dpu_encoder_cleanup_wb_job(struct drm_encoder *drm_enc, */ bool dpu_encoder_is_valid_for_commit(struct drm_encoder *drm_enc); +/** + * dpu_encoder_is_builtin - find if the encoder is of type builtin + * @drm_enc: Pointer to previously created drm encoder structure + */ +bool dpu_encoder_is_builtin(struct drm_encoder *drm_enc); + #endif /* __DPU_ENCODER_H__ */
