(v1) Changelog
[Why]
After commit c69dd2d "drm/amd/display: Refactor clk_mgr functions"
dc/clk_mgr requires these changes to add SI parts support
Necessary to avoid hitting default: ASSERT(0); /* Unknown Asic */
that would cause kernel freeze
[How]
Add case statement for FAMILY_SI chipsets
(v2) Changelog
[Why]
DCE6 has no DPREFCLK_CNTL register
[How]
Add DCE6 specific macros definitions for CLK registers and masks
Add DCE6 specific dce60/dce60_clk_mgr.c for DCE6 customization
Code style: reuse all the public functions in dce100/dce_clk_mgr.h header
Code style: use dce60_* static functions as per other DCE implementations
Add dce60_get_dp_ref_freq_khz() w/o using DPREFCLK_CNTL register
Use dce60_get_dp_ref_freq_khz() function in dce60_funcs
Add DCE6 specific dce60_clk_mgr_construct
dc/clk_mgr/dce_clk_mgr.c: use dce60_clk_mgr_construct for FAMILY_SI chipsets
Add Makefile rules for dce60_clk_mgr.o target conditional to CONFIG_DRM_AMD_DC_SI
(v3) Changelog
[Why]
linux-next kernel test robot reported the following problem:
warning: no previous prototype for 'dce60_get_dp_ref_freq_khz' [-Wmissing-prototypes]
[How]
mark dce60_get_dp_ref_freq_khz() as static
Fixes: 3ecb3b794e2 "drm/amd/display: dc/clk_mgr: add support for SI parts (v2)"
