Subject: amdgpu/pm: Implement emit_clk_levels for navi10
Git-commit: b06b48d7ddae440f3393e5c1ddda4d2537b3a7cc
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
(v4)
Modifications to satisfy checkpatch --strict
(v3)
Rewrote patchset to order patches as (API, hw impl, usecase)
- implement emit_clk_levels for navi10, based on print_clk_levels,
but using sysfs_emit without smu_cmn_get_sysfs() workaround
