- Support Freesync HDMI by calling DC interace
- Report Freesync capability to vrr_range debugfs from DRM

drm/amd/display: Fix MPC OGAM power on/off sequence
[Why]
Color corruption can occur on bootup into a login
manager that applies a non-linear gamma LUT because
the LUT may not actually be powered on before writing.
It's cleared on the next full pipe reprogramming as
we switch to LUTB from LUTA and the pipe accessing
the LUT has taken it out of light sleep mode.
[How]
The MPCC_OGAM_MEM_PWR_FORCE register does not force
the current power mode when set to 0. It only forces
when set light sleep, deep sleep or shutdown.
The register to actually force power on and ignore
sleep modes is MPCC_OGAM_MEM_PWR_DIS - a value of 0
will enable power requests and a value of 1 will
disable them.
When PWR_FORCE!=0 is combined with PWR_DIS=0 then
MPCC OGAM memory is forced into the state specified
by the force bits.
If PWR_FORCE is 0 then it respects the mode specified
by MPCC_OGAM_MEM_LOW_PWR_MODE if the RAM LUT is not
in use.
We set that bit to shutdown on low power, but otherwise
it inherits from bootup defaults.
So for the fix:
1. Update the sequence to "force" power on when needed
We can use MPCC_OGAM_MEM_PWR_DIS for this to turn on the
memory even when the block is in bypass and pending to be
enabled for the next frame.
We need this for both low power enabled or disabled.
If we don't set this then we can run into issues when we
first program the LUT from bootup.
2. Don't apply FORCE_SEL
Once we enable power requests with DIS=0 we run into the
issue of the RAM being forced into light sleep and being
unusable for display output. Leave this 0 like we used to
for DCN20.
3. Rely on MPCC OGAM init to determine light sleep/deep sleep
MPC low power debug mode isn't enabled on any ASIC currently
but we'll respect the setting determined during init if it
is.
Lightly tested as working with IGT tests and desktop color
adjustment.
4. Change the MPC resource default for DCN30
It was interleaving the dcn20 and dcn30 versions before
depending on the sequence.
5. REG_WAIT for it to be on whenever we're powering up the
memory
Otherwise we can write register values too early and we'll
get corruption.

This patch is to make the error log more clear for fine grain tuning

The fine grain tuning function uses the sysfs file -- pp_od_clk_voltage,

drm/amd/pm: add support for hwmon control of slow and fast PPT limit on vangogh
Implement hwmon API for reading/setting slow and fast PPT limit.
APU power is managed to system-level requirements through the PPT
(package power tracking) feature. PPT is intended to limit power to the
requirements of the power source and could be dynamically updated to
maximize APU performance within the system power budget.
Here FAST_PPT_LIMIT manages the ~10 ms moving average of APU power,
while SLOW_PPT_LIMIT manages the configurable, thermally significant
moving average of APU power (default ~5000 ms).
User could read slow/fast ppt limit using command "cat power*_cap" or
"sensors" in the hwmon device directory. User could adjust values of
slow/fast ppt limit as needed depending on workloads through command
"echo ## > power*_cap".
Example:
$ echo
15000000 > power1_cap
$ echo
18000000 > power2_cap
$ sensors
amdgpu-pci-0300
Adapter: PCI adapter
slowPPT: 9.04W (cap = 15.00 W)
fastPPT: 9.04W (cap = 18.00 W)
v2: align with existing interfaces for the getting/setting of PPT
limits. Encode the upper 8 bits of limit value to distinguish
slow and fast power limit type.
