DDI ports have its encoders initialized with INTEL_OUTPUT_DDI type and
later eDP ports that have the type changed to INTEL_OUTPUT_EDP.
But for all other DDI ports it can drive HDMI or DP depending on what
user connects to the ports.
ehl_get_combo_buf_trans() and tgl_get_combo_buf_trans() was checking
for INTEL_OUTPUT_DP that was never true, causing wrong vswing tables
being used.
So here replacing the INTEL_OUTPUT_DP checks by the valid output types
that this functions receives as parameters. HDMI cases will be
correctly handled as it do not use encoder->type, instead it calls the
functions with INTEL_OUTPUT_HDMI as type parameter and HDMI don't have
retraining.
v2:
changed INTEL_OUTPUT_DDI to INTEL_OUTPUT_EDP and INTEL_OUTPUT_HDMI

Pull btrfs updates from David Sterba:
"A number of core changes that make things work better in general, code
is simpler and cleaner.
Core changes:
- per-inode file extent tree, for in memory tracking of contiguous
extent ranges to make sure i_size adjustments are accurate
- tree root structures are protected by reference counts, replacing
SRCU that did not cover some cases
- leak detector for tree root structures
- per-transaction pinned extent tracking
- buffer heads are replaced by bios for super block access
- speedup of extent back reference resolution, on an example test
scenario the runtime of send went down from a hour to minutes
- factor out locking scheme used for subvolume writer and NOCOW
exclusion, abstracted as DREW lock, double reader-writer exclusion
(allow either readers or writers)
- cleanup and abstract extent allocation policies, preparation for
zoned device support
- make reflink/clone_range work on inline extents
- add more cancellation point for relocation, improves long response
from 'balance cancel'
- add page migration callback for data pages
- switch to guid for uuids, with additional cleanups of the interface
- make ranged full fsyncs more efficient
- removal of obsolete ioctl flag BTRFS_SUBVOL_CREATE_ASYNC
- remove b-tree readahead from delayed refs paths, avoiding seek and
read unnecessary blocks
Features:
- v2 of ioctl to delete subvolumes, allowing to delete by id and more
future extensions
Fixes:
- fix qgroup rescan worker that could block umount
- fix crash during unmount due to race with delayed inode workers
- fix dellaloc flushing logic that could create unnecessary chunks
under heavy load
- fix missing file extent item for hole after ranged fsync
- several fixes in relocation error handling
Other:
- more documentation of relocation, device replace, space
reservations
- many random cleanups"

Currently, all harts have to jump Linux in RISC-V. This complicates the
multi-stage boot process as every transient stage also has to ensure all
harts enter to that stage and jump to Linux afterwards. It also obstructs
a clean Kexec implementation.
SBI HSM extension provides alternate solutions where only a single hart
need to boot and enter Linux. The booting hart can bring up secondary
harts one by one afterwards.
Add SBI HSM based cpu_ops that implements an ordered booting method in
RISC-V. This change is also backward compatible with older firmware not
implementing HSM extension. If a latest kernel is used with older
firmware, it will continue to use the default spinning booting method.

Since a virtual mixer has no backing registers
to decide which path to connect,
it will try to match with initial state.
This is to ensure that the default mixer choice will be

Invert flag is used to select initial state of the virtual switch.
Since actual hardware can't be disconnected by virtual switch,

At the moment, playing audio with PulseAudio with the qdsp6 driver
results in distorted sound. It seems like its timer-based scheduling
does not work properly with qdsp6 since setting tsched=0 in
the PulseAudio configuration avoids the issue.
Apparently this happens when the pointer() callback is not accurate
enough. There is a SNDRV_PCM_INFO_BATCH flag that can be used to stop
PulseAudio from using timer-based scheduling by default.
According to https://www.alsa-project.org/pipermail/alsa-devel/2014-March/073816.html:
The flag is being used in the sense explained in the previous audio
meeting -- the data transfer granularity isn't fine enough but aligned
to the period size (or less).
q6asm-dai reports the position as multiple of
prtd->pcm_count = snd_pcm_lib_period_bytes(substream)
so it indeed just a multiple of the period size.
Therefore adding the flag here seems appropriate and makes audio
work out of the box.

Some displays have an issue where the hdcp chips are initialized after the
display has already lit up. This means we can sometimes authentication too early
and cause authentication failures.
This happens when HDCP is enabled and the display is power cycled. Normally we
will authenticate 2 seconds after the display is lit, but some displays need a
bit more time.

Increase delay to 3 second before we start authentication.

[How]
Use minimum refresh rate as nominal/2 when EDID dictates that min
refresh = max refresh/2.

[Why]
CTM was only supported at CRTC level and we need color space conversion
in linear space at plane level.
[How]
- Add plane-level CTM to dc interface
- Program plane-level CTM in DCN

[Why]
In some scenario like 1366x768 VSR enabled connected with a 4K monitor
and playing 4K video in clone mode, underflow will be observed due to
decrease dppclk when previouse surface scan isn't finished
[How]
In this use case, surface flip is switching between 4K and 1366x768,
1366x768 needs smaller dppclk, and when decrease the clk and previous
surface scan is for 4K and scan isn't done, underflow will happen. Not
doing optimize bandwidth in case of flip pending.

[Why]
For some monitors extreme flickering can occur while using LFC for if
we're not doing the DRR timing update for V_TOTAL_MIN / V_TOTAL_MAX at
the DP start of frame.
Hardware can default to any time in the frame which isn't the behavior
we want.
[How]
Add a new function for setting the double buffering mode for DRR timing.
Default to DP start of frame double buffering on timing generator init.
