2e8b807317 drm/i915/bios: Define VBT block 5 (Generic Mode Table) 
Define the contents of VBT block 5 (Generic Mode Table).

Details were mostly gleaned from some VBIOS sources.

There are apparently two variants of the block: ALM only
vs. MGM, defined here as bdb_generic_mode_table_alm
and bdb_generic_mode_table_mgm. And those are the only two
platforms where I've seen this block.

22794e6cee drm/i915/bios: Define VBT block 4 (Mode Support List) contents 
Define the contents of VBT block 4 (Mode Support List).

Slightly crazy layout with a variable length list at the start,
followed by the length of said list.

No real idea what these "Intel mode numbers" really are. What
I see in real world VBTs seems to be always the same list of
26 numbers, ranging between 0x30 and 0x84.

Define the contents of VBT block 3 (Display Toggle Option).

On modern VBTs this is just a single byte, but on ALM there is

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.

DEVICE_HANDLE_EFP4 has actually been in use since the very beginning,
or at least something has been occupying that bit because old
VBTs actually use it, and it definitely looks to be about external
displays given how its used. So let's ignore what the current spec

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")]

4071ada7ae drm/i915/display: perform transient flush 
Perform manual transient cache flush prior to flip and at the end of
frontbuffer_flush. This is needed to ensure display engine doesn't see
garbage if the surface is L3:XD dirty.

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.

v2: rebase(RK)

Xe2_HPD has different offsets for C20 PHY SRAM configuration context

Note that Xe2_LPD uses the same C20 SRAM offsets used by Xe_LPDP (i.e.
MTL's display). According to the BSpec, currently, only Xe2_HPD has
different offsets, so make sure it is the only display using them in the
driver.

* Redesigned how the right offsets are selected for different display
IP versions.
v3: Fix white space error(RK)
