fix and GA103 support for nouveau, a refcounting fix for meson, a NULL
pointer dereference fix for ttm, a error check fix for lvds-codec, a

drm/bridge: lvds-codec: Fix error checking of drm_of_lvds_get_data_mapping()

2022-08-10T23:44:15+00:00

The drm_of_lvds_get_data_mapping() returns either negative value on
error or MEDIA_BUS_FMT_* otherwise. The check for 'ret' would also
catch the positive case of MEDIA_BUS_FMT_* and lead to probe failure
every time 'data-mapping' DT property is specified.

Merge tag 'sound-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

2022-08-06T17:19:51+00:00

Pull sound updates from Takashi Iwai:
 "As the diffstat shows, we've had lots of developments in a wide range
  at this time; the majority of changes are about ASoC, including
  subsystem-wide cleanups, continued SOF / Intel updates and a bunch of
  new drivers (as usual), while there have been some significant (but
  almost invisible) improvements in ALSA core side, too.

  Below are some highlights:

  Core:

   - Faster lookups of control elements with Xarray; normal user won't
     notice, but on the devices with tons of control elements, it can be
     visibly faster

   - Support for input validation for controls; this will harden for
     badly written drivers in general with a slight overhead

   - Deferred async signal handling for working around the potential
     deadlocks

   - Cleanup / refactoring raw MIDI locking code

  ASoC:

   - Restructing of the set_fmt() callbacks for making things clearer in
     situations like CODEC to CODEC links

   - Clean up and modernizing the DAI naming scheme setups

   - Merge of more of the Intel AVS driver stack, including some board
     integrations

   - New version 4 mechanism for communication with SOF DSPs

   - Suppoort for dynamically selecting the PLL to use at runtime on
     i.MX platforms

   - Improvements for CODEC to CODEC support in the generic cards

   - Support for AMD Jadeite and various machines, AMD RPL, Intel
     MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
     MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
     WAS883x, and Texas Instruments TAS2780

  HD- and USB-audio:

   - Continued improvement for CS35L41 (sub)codec support

   - More quirks for various devices (HP, Lenovo, Dell, Clevo)"

Merge tag 'asoc-v5.20' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

2022-07-15T14:11:58+00:00

ASoC: Updates for v5.20

This is a big release thus far and there will probably be more changes
to come, it's a combination of a larger than usual crop of new drivers
and some subsysetm wide cleanups from Charles rather than anything
structural.  The SOF and Intel DSP code both also continue to be very
actively developed.

 - Restructing of the set_fmt() callbacks to be specified in terms of
   the device rather than with semantics depending on if the device is
   supposed to be a CODEC or SoC, making things clearer in situations
   like CODEC to CODEC links.
 - Clean up of the way we flag which DAI naming scheme we use to reflect
   the progress that's been made modernising things.
 - Merge of more of the Intel AVS driver stack, including some board
   integrations.
 - New version 4 mechanism for communication with SOF DSPs.
 - Suppoort for dynamically selecting the PLL to use at runtime on i.MX
   platforms.
 - Improvements for CODEC to CODEC support in the generic cards.
 - Support for AMD Jadeite and various machines, Intel MetorLake DSPs,
   Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP
   TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments
   TAS2780.

drm/bridge: ti-sn65dsi86: Use atomic variants of drm_bridge_funcs

2022-07-06T15:08:03+00:00

Move away from the deprecated enable/disable operations in
drm_bridge_funcs and enable atomic use.

v3:
 - Drop use of DRM_BRIDGE_STATE_OPS

v2:
 - fix build (kernel test robot )

drm/bridge: fsl-ldb: Fix mode clock rate validation

2022-07-06T13:33:08+00:00

With LVDS dual link, up to 160MHz mode clock rate is supported.
With LVDS single link, up to 80MHz mode clock rate is supported.
Fix mode clock rate validation by swapping the maximum mode clock
rates of the two link modes.

that aux transfer function wasn't used, do hpd polling check after pm
runtime resume, which will power on the bridge.
