This callback will setup the new input format and encoding from encoder, then these information will be used instead of the default ones in the dw_hdmi_setup() function. To determine the output bus format, has been added : - support for the connector display_info bus_formats, where a fixed output bus format can be enforced by the encoder - support for synami output bus format depending on the input format, especially the YUV420 input bus format, enforcing YUV420 as output with the correct bit depth Signed-off-by: Neil Armstrong --- drivers/gpu/drm/bridge/synopsys/dw-hdmi.c | 121 ++++++++++++++++++++-- 1 file changed, 112 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/bridge/synopsys/dw-hdmi.c b/drivers/gpu/drm/bridge/synopsys/dw-hdmi.c index 325a87a82048..67f8788de213 100644 --- a/drivers/gpu/drm/bridge/synopsys/dw-hdmi.c +++ b/drivers/gpu/drm/bridge/synopsys/dw-hdmi.c @@ -103,6 +103,8 @@ struct hdmi_vmode { };
