drm/amd/display: rename DCN1_0 kconfig to DCN

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

Since dcn20 and dcn21 are under dcn1 it doesnt make sense to
have it named dcn1.

Change it to "dcn" to make it generic

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()

drm/amd/display: fix a potential null pointer dereference

2019-08-22T22:25:33+00:00

Currently the pointer init_data is dereferenced on the assignment
of fw_info before init_data is sanity checked to see if it is null.
Fix te potential null pointer dereference on init_data by only
performing dereference after it is null checked.

[Why]
Seamless boot (building SW state inheriting BIOS-initialized timing) was
enabled on DCN2, including fixes

[How]
Includes fixes for MPC, DPPCLK, and DIG FE mapping/OTG source select/
Pixel clock.

This is part 2 of 2 for seamless boot NV10

drm/amd/display: make firmware info only load once during dc_bios create

2019-08-15T15:53:36+00:00

Currently every time DC wants to access firmware info we make a call
into VBIOS. This makes no sense as there is nothing that can change
runtime inside fw info and can cause issues when calling unstable
bios during bringup.

This change eliminate this behavior by only calling bios once for fw
info and keeping it stored as part of dc_bios.
