e225161e2a drm/i915/bios: Define VBT blocks 19,30,32 (Display Configuration Removal Table) contents 
Define the contenst is VBT blocks 19,30,32 (Display Configuration
Removal Table) contents. There are three variants of this block:
pre-IVB, IVB, HSW+, with each having slightly different entries.

Curiously many HSW/BDW machines seem to have both the IVB and HSW+
variants in their VBTs simultanously. No idea why.

55c6b98676 drm/i915/bios: Define ALM only VBT block 9 contents 
For some reason ALM VBT has two dot clock override tables.
One as the normal block 15 and a second one as block 9.
The table in block 9 has no row_size/num_rows information.

On my Fujitsu Lifebook S6010 only the block 9 table has actual
data in it. Block 15 is present but all zeroes.

There are apparently two variants of the block: ALM only

platforms where I've seen this block.

Slightly crazy layout with a variable length list at the start,

10632fcbf0 drm/i915/bios: Define "TV" child device handle 
Child device 0x2 used to be "TV" until redefined to mean
EFP5 in version 215. Add a define for the old meaning as well.

Technically it was probably deprecated a lot before version
215 since native TV encoders were last seen on CTG, and SDVO
was fully gone by HSW. So something like "???-164" might also
be a reasonable way to document this, but no real harm in
saying "???-214" since nothing else presumably occupied that
bit in the meantime.

c286f6a973 drm/i915/bios: Fix parsing backlight BDB data 
Starting BDB version 239, hdr_dpcd_refresh_timeout is introduced to
backlight BDB data. Commit 700034566d ("drm/i915/bios: Define more BDB
contents") updated the backlight BDB data accordingly. This broke the
parsing of backlight BDB data in VBT for versions 236 - 238 (both
inclusive) and hence the backlight controls are not responding on units
with the concerned BDB version.

backlight_control information has been present in backlight BDB data
from at least BDB version 191 onwards, if not before. Hence this patch
extracts the backlight_control information for BDB version 191 or newer.
Tested on Chromebooks using Jasperlake SoC (reports bdb->version = 236).
Tested on Chromebooks using Raptorlake SoC (reports bdb->version = 251).

v2: removed checking the block size of the backlight BDB data
    [vsyrjala: this is completely safe thanks to commit e163cfb4c9
     ("drm/i915/bios: Make copies of VBT data blocks")]

c01c6066e6 drm/xe/device: implement transient flush 
Display surfaces can be tagged as transient by mapping it using one of
the various L3:XD PAT index modes on Xe2. The expectation is that KMD
needs to request transient data flush at the start of flip sequence to
ensure all transient data in L3 cache is flushed to memory. Add a
routine for this which we can then call from the display code.

For BMG it seems that the VBT to DDI mapping does not follow DG1, and
DG2, but follows ADLP mapping given in Bspec:20124.
