drm/amd/pm: Add support to set min ISP clocks2025-06-24T14:02:44+00:00Pratap Nirujogipratap.nirujogi@amd.com2025-06-16T18:16:43+00:00urn:sha1:9bed716f8722999a2b15a2e5df4dfca48e4c06c9
Add support to set ISP clocks for SMU v14.0.0. ISP driver
uses amdgpu_dpm_set_soft_freq_range() API to set clocks via
SMU interface than communicating with PMFW directly.
amdgpu_dpm_set_soft_freq_range() is updated to take in any
pp_clock_type than limiting to support only PP_SCLK to allow
ISP and other driver modules to set the min/max clocks. Any
clock specific restrictions are expected to be taken care in
SOC specific SMU implementations instead of generic amdgpu_dpm
and amdgpu_smu interfaces.

Add an instance parameter to set_powergating_by_smu() function, and
re-write all amd_pm functions accordingly. Then use the instance to
call smu_dpm_set_vcn_enable().
v2: remove duplicated functions.
remove for-loop in smu_dpm_set_power_gate(), and temporarily move it to
to amdgpu_dpm_set_powergating_by_smu(), in order to keep the exact same
logic as before, until further separation in next patch.
v3: add instance number in error message.
