a640e3c3a5 drm/amd/pm: Annotate struct smu10_voltage_dependency_table with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct smu10_voltage_dependency_table.

ade134ddae drm/amd: Fix logic error in sienna_cichlid_update_pcie_parameters()
While aligning SMU11 with SMU13 implementation an assumption was made that
`dpm_context->dpm_tables.pcie_table` was populated in dpm table initialization
like in SMU13 but it isn't.

So restore some of the original logic and instead just check for
amdgpu_device_pcie_dynamic_switching_supported() to decide whether to hardcode
values; erring on the side of performance.

d62846f778 amdgpu/pm: Optimize emit_clock_levels for aldebaran - part 2
Use variables to remove ternary expression in print statement
 and improve readability. This will help to optimize the code
 duplication in the switch statement
 Also Changed:
  replaced single_dpm_table->count as iterator in for loops
    with safer clocks_num_levels value
  replaced dpm_table.value usage with local var clocks_mhz

2ecf214b45 amdgpu/pm: Optimize emit_clock_levels for aldebaran - part 1
Use variables to remove the multiple nested ternary expressions
 and improve readability. This will help to optimize the code
 duplication in the switch statement
 Also Changed:
  Modify function aldebaran_get_clk_table to void function as it
    always returns 0
  Use const string "attempt_string" to cut down on repetition

bc22d9e0ee amdgpu/pm: Replace print_clock_levels with emit_clock_levels for aldebaran
Replace print_clock_levels with emit_clock_levels for aldebaran
  * replace .print_clk_levels with .emit_clk_levels in aldebaran_ppt_funcs
  * added extra parameter int *offset
  * removed var size, uses arg *offset instead
  * removed call to smu_cmn_get_sysfs_buf
  * errors are returned to caller
  * returns 0 on success
additional incidental changes
  * changed type of vars i, now to remove comparing mismatch types
  * renamed var s/now/cur_value/
  * switch statement default now returns -EINVAL
  * RAS Recovery returns -EBUSY

Based on
  commit b06b48d7dd ("amdgpu/pm: Implement emit_clk_levels for navi10")

2e3b2cb9b8 drm/amd/pm: only poweron/off vcn/jpeg when they are valid.
If vcn is disabled in kernel parameters, don't touch vcn,
otherwise it may cause vcn hang.

v2: delete unnecessary logs
v3: move "is_vcn_enabled" check to smu_dpm_setvcn/jpeg_enable (Evan)
