Having the plane WM/DDB regitster write functions in skl_watermarks.c is rather annoying when trying to implement DSB based plane updates. Move them into the respective files that handle all other plane register writes. Less places where I need to worry about the DSB vs. MMIO decisions. The downside is that we spread the wm struct details a bit further afield. But if that becomes too annoying we can probably abstract things a bit more with a few extra functions. Signed-off-by:

Get rid of skl_ddb_entry_write() and skl_write_wm_level() and just call intel_de_write_fw() directly. This is prep work towards DSB based plane updates where these wrappers are more of a hinderance. Done with cocci mostly: @@ expression D, R, L; @@ - skl_write_wm_level(D, R, L) + intel_de_write_fw(D, R, skl_plane_wm_reg_val(L)) @@ expression D, R, B; @@ - skl_ddb_entry_write(D, R, B) + intel_de_write_fw(D, R, skl_plane_ddb_reg_val(B)) Signed-off-by:

Currently every skl+ plane register defines some intermediate macros to calculate the final register offset. Pull all of that into common macros, simplifying the final register offset stuff into just five defines: - raw register offsets for the planes 1 and 2 on pipes A and B - the final parametrized macro v2: Rebase Signed-off-by:

Add panel replay selective update support to debugfs status interface. In case of sink supporting panel replay we will print out: Sink support: PSR = no, Panel Replay = yes, Panel Replay Selective Update = yes and PSR mode will look like this if printing out enabled panel replay selective update: PSR mode: Panel Replay Selective Update Enabled Current PSR and panel replay printouts remain same.

The function descriptions are optional and have not yet been added to the DMC wakelock code, so we shouldn't try to use it.

WA_14020863754: Corner case with Min Hblank Fix can cause audio hang Issue: Previously a fix was made to avoid issues with extremely small hblanks, called the "Min Hblank Fix". However, this can potentially cause an audio hang. Workaround : During "Audio Programming Sequence" Audio Enabling - When DP mode is enabled Set mmio offset 0x65F1C bit 18 = 1b, before step #1 "Enable audio Presence Detect" During "Audio Programming Sequence" Audio Disabling - When DP mode is enabled Clear mmio offset 0x65F1C bit 18 = 0b, after step #6 "Disable Audio PD (Presence Detect)" If not clearing PD bit, must also not clear 0x65F1C bit 18 (leave = 1b) v2: Update the platform checks (Jani Nikula) v3: Limited the WA to LNL and BMG, added a helper (Matt Roper) v4: Updated the bit naming, fixed redundant if statement Signed-off-by:
