9c0fb8d45b drm/amd/display: refactor programming of DRR
[Why]
Keep enable_stream_timing programming only
timing related stuff.

[How]
Move DRR and static screen mask programming from
enable_stream_timing to outside in
apply_single_controller_ctx_to_hw

d2d7885f75 drm/amd/display: add seamless boot flag to stream
[Why]
If we determine the stream we are trying to commit
matches HW, we want to try to optimize.

[How]
Try to acquire the HW resources that are already enabled
and optimize.
Also skip backend reprogramming

ff582b6146 drm/amd/display: add way to determine if link is active
[Why]
Need to understand whether link is active aside from stream state.
This could be used to check what links are enabled by GOP.

[How]
Store link_active state in link status and initialize it by checking
if the DIG is enabled.
Keep it updated on every link enable and disable

68f1a00c23 drm/amd/display: interface to check if timing can be seamless
[Why]
Need to figure out whether a timing we want to commit matches
something that GOP already programmed, in which case
we can decide to some optimizations

[How]
1. Add way to check for DIG FE
2. Add way to check for matching OTG timing
3. Add way to check for matching pixel clock (if possible)
    - Currently only support DP for pixel clock, since it is easy to calc

e6d2421343 drm/amd/display: PIP overlay corruption
[Why]
When moving mouse onto or off of pip plane,
screen would flash briefly due to garbage negative
pos values being programmed for cursor.
Also, text flashes due to PIP flips taking too long.

[How]
When negative pos value seen, default to 0 and adjust by modifying cursor hotspot.
For flip issue, only do post update when optimize required vs all the time.

5062b797db drm/amd/display: Don't re-program planes for DPMS changes
[Why]
There are opt1c lock warnings and CRTC read timeouts when running the
"igt@kms_plane@plane-position-hole-dpms-pipe-*" tests. These are
caused by trying to reprogram planes that are not in the current
context.

DPMS off removes the stream from the context. In this case:

new_crtc_state->active_changed = true
new_crtc_state->mode_changed = false

The planes are reprogrammed before the stream is removed from the
context because stream_state->mode_changed = false.

For DPMS adds the stream and planes back to the context:

new_crtc_state->active_changed = true
new_crtc_state->mode_changed = false

The planes are also reprogrammed here before the stream is added to the
context because stream_state->mode_changed = true. They were not
previously in the current context so warnings occur here.

[How]
Set stream_state->mode_changed = true when
new_crtc_state->active_changed = true too.

This prevents reprogramming before the context is applied in DC. The
programming will be done after the context is applied.

3ccaf57a6a XArray: Add support for 1s-based allocation
A lot of places want to allocate IDs starting at 1 instead of 0.
While the xa_alloc() API supports this, it's not very efficient if lots
of IDs are allocated, due to having to walk down to the bottom of the
tree to see if ID 1 is available, then all the way over to the next
non-allocated ID.  This method marks ID 0 as being occupied which wastes
one slot in the XArray, but preserves xa_empty() as working.

  - Address of the trampoline is returned in RAX.

But, ssi user count (= ssi->usrcnt) is incremented at .init
(= rsnd_ssi_init()).
Because of these timing exchange, ssi->usrcnt check at
rsnd_ssi_master_clk_start() should be adjusted.
Otherwise, 2nd master clock setup will be no check.
This patch fixup this issue.

ASoC: dapm: fix out-of-bounds accesses to DAPM lookup tables
KASAN reports and additional traces point to out-of-bounds accesses to
the dapm_up_seq and dapm_down_seq lookup tables. The indices used are
larger than the array definition.

Fix by adding missing entries for the new widget types in these two
lookup tables, and align them with PGA values.

Also the sequences for the following widgets were not defined. Since
their values defaulted to zero, assign them explicitly

 snd_soc_dapm_input
 snd_soc_dapm_output
 snd_soc_dapm_vmid
 snd_soc_dapm_siggen
 snd_soc_dapm_sink

Fixes: 8a70b4544e ('ASoC: dapm: Add new widget type for constructing DAPM graphs on DSPs.').

spi: atmel-quadspi: add support for sam9x60 qspi controller
The sam9x60 qspi controller uses 2 clocks, one for the peripheral register
access, the other for the qspi core and phy. Both are mandatory. It uses
different transfer type bits in IFR register. It has dedicated registers
to specify a read or a write instruction: Read Instruction Code Register
(RICR) and Write Instruction Code Register (WICR). ICR/RICR/WICR have
identical fields.

Tested with sst26vf064b jedec,spi-nor flash. Backward compatibility test
done on sama5d2 qspi controller and mx25l25635e jedec,spi-nor flash.

spi: atmel-quadspi: add support for named peripheral clock
Naming clocks is a good practice. Keep supporting unnamed
peripheral clock, to be backward compatible with old DTs.
While here, rename clk to pclk, to indicate that it is a
peripheral clock.

spi: atmel-quadspi: rework transfer macros
Split the TFRTYP_TRSFR_ bitfields in 2: one bit encoding the
mem/reg transfer type and one bit encoding the direction of
the transfer (read/write).

Remove NOP when setting read transfer type. Remove useless
setting of write transfer type when
op->data.dir == SPI_MEM_DATA_IN && !op->data.nbytes.

QSPI_IFR_TFRTYP_TRSFR_WRITE is specific just to sama5d2 qspi,
rename it to QSPI_IFR_SAMA5D2_WRITE_TRSFR.
