2023-04-03drm/i915/tc: Add TC PHY hooks to get the PHY ready/owned stateImre Deak
Add TC PHY hooks to get the PHY ready/owned state on each platform, replacing the corresponding if ladder.

2023-04-03drm/i915/tc: Add TC PHY hook to get the PHY HPD live statusImre Deak
Add a table of TC PHY hooks which can be used to call platform specific TC PHY handlers, replacing the corresponding if ladders. Add the hook to retrieve the PHY's HPD live status. Move the common part fixing up the VBT legacy port flag to the generic helper.

2023-04-03drm/i915/tc: Move TC port fields to a new intel_tc_port structImre Deak
Move the TC port specific fields from intel_digital_port to a new intel_tc_port struct. Pass an intel_tc_port pointer to all static functions in intel_tc.c keeping dig_port accessible for these via a pointer stored in the new struct. The next patch will allocate the intel_tc_port dynamically, allowing moving the struct definition to intel_tc.c.

2023-04-03drm/i915/dsc: Add debugfs entry to validate DSC output formatsSwati Sharma
DSC_Output_Format_Sink_Support entry is added to i915_dsc_fec_support_show to depict if sink supports DSC output formats (RGB/YCbCr420/YCbCr444). Also, new debugfs entry is created to enforce output format. This is required because of our driver policy. For ex. if a mode is supported in both RGB and YCbCr420 output formats by the sink, our policy is to try RGB first and fall back to YCbCr420, if mode cannot be shown using RGB. So, to test other output formats like YCbCr420 or YCbCr444, we need a debugfs entry (force_dsc_output_format) to force this output format. v2: -Func name changed to intel_output_format_name() (Jani N) -Return forced o/p format from intel_dp_output_format() (Jani N) v3: -output_format_str[] to remain static (Jani N) Signed-off-by: Swati Sharma <swati2.sharma@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230309062855.393087-8-suraj.kandpal@intel.com

2023-03-31drm/amd/display: Conditionally enable 6.75 GBps link rateArtem Grishin
[Why] The 6.75 GBps link rate is part of the new eDP specification version 1.5 is going to be supported in the future. Since this standard is very new and there are no existing 6.75 GBps panels on the market yet, we should put a condition in the driver on enabling this feature until we can validate it with real hardware. [How] - Add boolean flag support_eDP1_5 in struct dc_debug_options. - Enable the 6.75 link rate in reduce_link_rate(...) only when the flag is true.

2023-03-31drm/amd/display: fixed dcn30+ underflow issueAyush Gupta
[Why] Observing underflow on dcn30+ system config at 4k144hz [How] We set the UCLK hardmax on AC/DC switch if softmax is enabled and also on boot. While booting up the UCLK Hardmax is set to softmax before the init sequence and the init sequence resets the hardmax to UCLK max which enables P-state switching. Just added a conditional check to avoid setting hardmax on init.
