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: refactor gpio to allocate hw_container in constructor

2019-08-15T15:53:55+00:00

drm/amd/display: Change offset_to_id to reflect what id_to_offset returns

2019-07-18T19:27:25+00:00
