Bspec requires disabling the DPLLs on TC ports before disconnecting the port's PHY. Add a post_pll_disable encoder hook and move the call to disconnect the port's PHY from the post_disable hook to the new hook. Reviewed-by:

The spec requires disabling the PLL on TC ports before disconnecting the port's PHY. Prepare for that by moving the PLL disabling to the CRTC disable hook, while disconnecting the PHY will be moved to the post_pll_disable() encoder hook in the next patch. v2: Move the call from intel_crtc_disable_noatomic() as well.

Bspec has updated the TC connect/disconnect sequences, add the required platform hooks for these. The difference wrt. the old sequence is the order of taking the PHY ownership - while holding a port power reference this requires - and blocking the TC-cold power state. Bspec: 49294 Reviewed-by:

Imre Deak authored
Connecting the PHY for connector probing - also blocking TC-cold - isn't required and has some overhead. Taking only the mutex is sufficient, so do that. Reviewed-by:

Enable the power required for the HPD live status register access instead of depending on the caller blocking the TC-cold power state (during HW readout and connector probing). A follow up patch will remove connecting/disconnecting the PHY around connector probing, so querying the HPD status can happen in this case without TC-cold being blocked. Reviewed-by:

The spec says to use the CPU ISR registers for DP-alt/TBT HPD detection on ADLP, so do that instead of using the related IOM/TCSS registers. Bspec: 55480, 55482, 49212, 49305 Reviewed-by:

Add a hook for platform specific PHY initialization. Move the detection of modular FIAs to the TGL handler, skipping this on ADLP+ where the FIAs are always modular, not requiring a detection. Reviewed-by:

Instead of the corresponding if ladder, add a TC PHY hook to get the platform and TC mode specific power domain used for blocking the TC-cold power state. Reviewed-by:

Imre Deak authored
Simplify tc_cold_block()/unblock() by dropping their power domain parameter. The power domain depends on the current TC mode, which - after the previous patch - can't change while the PHY is connected, holding a TC-cold-off power domain reference. Based on this the domain can be deducted from the current TC mode instead of having to pass this as a parameter. Blocking TC-cold for the PHY HW readout happens before the current TC mode is determined, so here the initial power domain must be still manually passed. For debugging still keep track of the domain used for tc_cold_block() and verify that it remained the same until tc_cold_unblock(). While at it rename tc_cold_get_power_domain() to tc_phy_cold_off_domain(), reflecting the name of platform specific hook added in the next patch. Reviewed-by:

After the previous patch unblock_tc_cold() will not be called in a disconnected mode, so the wakeref passed to it will be always non-zero. Remove the redundant check. Reviewed-by:

Move blocking/unblocking the TC-cold power state to the platform specific PHY connect / disconnect hooks. This allows for adjusting the connect/disconnect sequence as required for each platform. Reviewed-by:

After the previous patch the TC mode in the connect/disconnect functions is always in sync with the VBT legacy port flag, so for consistency with the rest of the function check the TC mode instead of the VBT flag. Reviewed-by:

Imre Deak authored
A follow-up patch simplifies the tc_cold_block()/unblock() functions, dropping the power domain parameter. For this it must be ensured that the power domain - which depends on the actual TC mode and so the VBT legacy port flag - can't change while the PHY is in a connected state and accordingly TC-cold is blocked. Make this so, by fixing up the VBT legacy flag only in the disconnected TC mode, instead of whenever the HPD state is retrieved. Reviewed-by:

Add generic handlers to connect/disconnect a PHY. Setting the TC mode to the target mode deducted from the HPD state and - if connecting to this mode fails - falling back to connecting to the default (TBT) mode are common to all platforms; move the logic for this from the ICL specific connect / disconnect handlers to the generic ones.

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:

Implementation of VDSC for YCbCr420.

Based on that appropriate qp table need to be chosen. Other rc_parameters need to be set where currently values for 444 format is hardcoded in calculate_rc_parameters( ). vdsc_cfg struct needs to be filled with output format information, where these are hardcoded for 444 format.
