From ICL onwards DDI/TypeC ports - even in HDMI static mode - need to know which AUX CH belongs to them, so initialize aux_ch for those ports too. For consistency do this for all HDMI ports, not only for DDI/TypeC ones.

First of all I believe this WA as written here was wrong. Because it is listed on BSpec only for SKL and BXT, exactly the only 2 platforms skipped here. But also it is written there that we don't need this WA anymore: "This workaround is no longer needed since NV12 support is dropped for the affected projects in #0870." SO, let's kill it.

Use intel_panel_actually_set_backlight() instead of a direct call to pwm_config() in pwm_disable_backlight(). The main benefit is consistent debug logging when we turn off the backlight. Currently we see nothing in dmesg which made me wonder whether the backlight was even getting turned off properly. The second benefit is consistency; This is what we do for all the other backlight implementations. Signed-off-by:

DSC is supported on eDP starting GEN 10 display (on GLK) and on DP starting GEN 11. This patch implements the discovery phase of DSC. On hotplug, source reads the DSC DPCD register set (0x00060 - 0x0006F) to read the decompression capabilities of the sink device. This entire block of registers is cached in intel_dp so that capability information can be used during DSC configuration phase during compute_config phase of the modeset. For eDP, this caching happens during the eDP initialization. This caching is done only for eDP and DP rev >= 1.4 v5: * Fix the block comment (Gaurav) * Fix the commit message DSC DPCD addresses (Gaurav) * Use DRM_ERROR for dpcd_read fail (Gaurav,Anusha) v4: * Cache these only for Gen >= 11 v3: * Remove the dsc_sink_support field in intel_dp (Jani N) v2: * Clear the cached registers on hotplug always (Jani N) * Combine the eDP and DP caching in same function (Jani N) Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Gaurav K Singh <gaurav.k.singh@intel.com> Signed-off-by:

Program the timeout values (in escape clock) for HS TX, LP RX and TA timeout. HX TX: Ensure that host does not continuously transmit in the HS state. If this timer expires, then host will gracefully end its HS transmission and allow the link to enter into LP state. LP RX: Monitor the length of LP receptions from Peripheral. If timeout happens then host will drive the stop state onto all data lanes (only Data Lane 0 should be receiving anything from the Peripheral). This effectively takes back ownership of the bus transmit in the HS state. TA timeout: Timeout valuefor monitoring Bus Turn-Around (BTA) sequence. BTA sequence should complete within a bounded amount of time, with peripheral acknowledging BTA by driving the stop state. v2 by Jani: - Rebase - Use intel_dsi_bitrate() and intel_dsi_tlpx_ns(intel_dsi) - Squash HX TX, LP RX and TA timeout into one patch - Fix bspec mode set sequence reference - Add FIXME about two timeouts Signed-off-by:
