drm/amd/display: determine USB C DP2 mode only when USB DP Alt is enabled

2020-04-09T14:43:17+00:00

[why] When display is connected with a native DP port, DP2 mode register value is a don't care. Driver mistakenly reduce max supported lane count to 2 lane based on the don't care value. [how] Add additional check only if USB C DP alt mode is enabled, we will determine max lane count supported based on current mode.

drm/amd/display: Drop CONFIG_DRM_AMD_DC_DCN2_0 and DSC_SUPPORTED

2019-11-13T20:29:44+00:00

[Why] DCN2 and DSC are stable enough to be build by default. So drop the flags. [How] Remove them using the unifdef tool. The following commands were executed in sequence: $ find -name '*.c' -exec unifdef -m -DCONFIG_DRM_AMD_DC_DSC_SUPPORT -DCONFIG_DRM_AMD_DC_DCN2_0 -UCONFIG_TRIM_DRM_AMD_DC_DCN2_0 '{}' ';' $ find -name '*.h' -exec unifdef -m -DCONFIG_DRM_AMD_DC_DSC_SUPPORT -DCONFIG_DRM_AMD_DC_DCN2_0 -UCONFIG_TRIM_DRM_AMD_DC_DCN2_0 '{}' ';' In addition: * Remove from kconfig, and replace any dependencies with DCN1_0. * Remove from any makefiles. * Fix and cleanup NV defninitions in dal_asic_id.h * Expand DCN1 ifdef to include DCN2 code in the following files: * clk_mgr/clk_mgr.c: dc_clk_mgr_create() * core/dc_resources.c: dc_create_resource_pool() * dce/dce_dmcu.c: dcn20_*lock_phy() * dce/dce_dmcu.c: dcn20_funcs * dce/dce_dmcu.c: dcn20_dmcu_create() * gpio/hw_factory.c: dal_hw_factory_init() * gpio/hw_translate.c: dal_hw_translate_init() Signed-off-by: Leo Li Signed-off-by: Bhawanpreet Lakha Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amd/display: set MSA MISC1 bit 6 while sending colorimetry in VSC SDP

2019-11-13T20:29:43+00:00

[Why] It is confusing to sinks if we send VSC SDP only on some format. Today we signal colorimetry format using MSA while in formats like sRGB. But when we switch to BT2020 we set the bit to ignore MSA colorimetry and instead use the colorimetry information in the VSC SDP. But if sink supports signaling of colorimetry via VSC SDP we should always set the MSA MISC1 bit 6, instead of doing so selectively. [How] If sink supports signaling of colorimetry via VSC SDP, and we are sending the colorimetry info via VSC SDP with packet revision 05h, then always set MSA MISC1 bit 6.
