586ec5dc5c drm/amd/display: do not force UCLK DPM to stay at highest state during display off in DCN2
[Why]
Add optimization to allow pstate change support when all displays
are off in DCN2.

[How]
Add clk_mgr_helper_get_active_plane_cnt() to sum plane_count for all
valid stream_status[].  If plane_count is 0, then there are no active
or virtual streams present. Use plane_count == 0 as extra condition to
enable p_state_change_support in dcn2_update_clocks().

the registers will still cause power to be consumed, so don't
program for NV12.

8144148f3d drm/amd/display: update scaling filters
Currently there is a minor error in scaling filter coefficients
caused by truncation to fit the HW registers.This error accummulates
with increased taps, but has gone unnoticed due to vast majority of
scaling being done with only 4 taps.

Scaling filters are now updated using HW team's filter generator
which has quantization error minimization built in.

f739ce5768 drm/amd/display: Add aconnector condition check for dpcd read
[Why]
core_link_read_dpcd() will invoke dm_helpers_dp_read_dpcd(),
which needs to read dpcd info with the help of aconnector.
If aconnector (dc->links[i]->prev) is NULL, then dpcd status
 cannot be read.

As a result, dpcd read fails and a line of error will be
printed out in dmesg.log as:
"*ERROR* Failed to found connector for link!"

[How]
Make sure that aconnector (dc->links[i]->prev) is not NULL,
then read dpcd status.

85e148fb96 drm/amd/display: fix workaround for incorrect double buffer register for DLG ADL and TTU
[Why]
these registers should have been double buffered. SW workaround we will have SW program the more aggressive (lower) values
whenever we are upating this register, so we will not have underflow at expense of less optimzal request pattern.

[How]
there is a driver bug where we don't check for 0, which is uninitialzed HW default.  since 0 is smaller than any value we need to program,
driver end up with not programming these registers

04ad71bd14 drm/amd/display: Use uint64_t logger_mask instead of uint32_t
[WHY]
enum dc_log_type has more than 32 entries. User cannot set larger entries,
like LOG_DSC. Logs from LOG_GAMMA_DEBUG where being printed even though
flag was not enabled, because dal_logger_should_log check erroneously
passed.

[HOW]
Change struct dal_logger.mask and struct dc_init_data.mask to uint64_t.

Previous logic is only good for 15W parts. Other configuration
