This format can be used in pipeline for negotiating bus format between the DSI-end of this bridge and the other component closer to pipeline components. v3: * include media-bus-format.h v2: * none v1: * new patch Signed-off-by: Jagan Teki --- drivers/gpu/drm/bridge/samsung-dsim.c | 28 +++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) diff --git a/drivers/gpu/drm/bridge/samsung-dsim.c b/drivers/gpu/drm/bridge/samsung-dsim.c index 376e9682e130..2584343b767a 100644 --- a/drivers/gpu/drm/bridge/samsung-dsim.c +++ b/drivers/gpu/drm/bridge/samsung-dsim.c @@ -15,6 +15,7 @@ #include #include #include +#include #include #include @@ -1339,6 +1340,32 @@ static void samsung_dsim_atomic_post_disable(struct drm_bridge *bridge, pm_runtime_put_sync(dsi->dev); } +#define MAX_INPUT_SEL_FORMATS 1 + +static u32 * +samsung_dsim_atomic_get_input_bus_fmts(struct drm_bridge *bridge, + struct drm_bridge_state *bridge_state, + struct drm_crtc_state *crtc_state, + struct drm_connector_state *conn_state, + u32 output_fmt, + unsigned int *num_input_fmts) +{ + u32 *input_fmts; + + *num_input_fmts = 0; + + input_fmts = kcalloc(MAX_INPUT_SEL_FORMATS, sizeof(*input_fmts), + GFP_KERNEL); + if (!input_fmts) + return NULL; + + /* This is the DSI-end bus format */ + input_fmts[0] = MEDIA_BUS_FMT_RGB888_1X24; + *num_input_fmts = 1; + + return input_fmts; +} + static int samsung_dsim_atomic_check(struct drm_bridge *bridge, struct drm_bridge_state *bridge_state, struct drm_crtc_state *crtc_state, @@ -1378,6 +1405,7 @@ static const struct drm_bridge_funcs samsung_dsim_bridge_funcs = { .atomic_duplicate_state = drm_atomic_helper_bridge_duplicate_state, .atomic_destroy_state = drm_atomic_helper_bridge_destroy_state, .atomic_reset = drm_atomic_helper_bridge_reset, + .atomic_get_input_bus_fmts = samsung_dsim_atomic_get_input_bus_fmts, .atomic_check = samsung_dsim_atomic_check, .atomic_pre_enable = samsung_dsim_atomic_pre_enable, .atomic_enable = samsung_dsim_atomic_enable,
