Merge tag 'i2c-for-6.8-rc1-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

2024-01-19T01:29:01+00:00

Pull i2c updates from Wolfram Sang:
 "This removes the currently unused CLASS_DDC support (controllers set
  the flag, but there is no client to use it).

  Also, CLASS_SPD support gets simplified to prepare removal in the
  future. Class based instantiation is not recommended these days
  anyhow.

  Furthermore, I2C core now creates a debugfs directory per I2C adapter.
  Current bus driver users were converted to use it.

  Finally, quite some driver updates. Standing out are patches for the
  wmt-driver which is refactored to support more variants.

  This is the rebased pull request where a large series for the
  designware driver was dropped"

drm: remove I2C_CLASS_DDC support

2024-01-18T20:10:41+00:00

After removal of the legacy EEPROM driver and I2C_CLASS_DDC support in
olpc_dcon there's no i2c client driver left supporting I2C_CLASS_DDC.
Class-based device auto-detection is a legacy mechanism and shouldn't
be used in new code. So we can remove this class completely now.

drm/msm/dp: call dp_display_get_next_bridge() during probe

2023-12-14T07:27:46+00:00

The funcion dp_display_get_next_bridge() can return -EPROBE_DEFER if the
next bridge is not (yet) available. However returning -EPROBE_DEFER from
msm_dp_modeset_init() is not ideal. This leads to -EPROBE return from
component_bind, which can easily result in -EPROBE_DEFR loops.

drm/msm/dpu: Drop enable and frame_count parameters from dpu_hw_setup_misr()

2023-12-14T07:27:45+00:00

Drop the enable and frame_count parameters from dpu_hw_setup_misr() as they
are always set to the same values.

In addition, replace MISR_FRAME_COUNT_MASK with MISR_FRAME_COUNT as
frame_count is always set to the same value.

drm/msm/dpu: Add mutex lock in control vblank irq

2023-12-14T07:27:45+00:00

Add a mutex lock to control vblank irq to synchronize vblank
enable/disable operations happening from different threads to prevent
race conditions while registering/unregistering the vblank irq callback.

v4: -Removed vblank_ctl_lock from dpu_encoder_virt, so it is only a
    parameter of dpu_encoder_phys.
    -Switch from atomic refcnt to a simple int counter as mutex has
    now been added
v3: Mistakenly did not change wording in last version. It is done now.
v2: Slightly changed wording of commit message

drm/msm/dpu: introduce separate wb2_format arrays for rgb and yuv

2023-12-14T07:27:39+00:00

Lets rename the existing wb2_formats array wb2_formats_rgb to indicate
that it has only RGB formats and can be used on any chipset having a WB
block.

Introduce a new wb2_formats_rgb_yuv array to the catalog to
indicate support for YUV formats to writeback in addition to RGB.

Chipsets which have support for CDM block will use the newly added
wb2_formats_rgb_yuv array.

changes in v3:
	- change type of wb2_formats_rgb/wb2_formats_rgb_yuv to u32
	  to fix checkpatch warnings

drm/msm/dpu: reserve cdm blocks for writeback in case of YUV output

2023-12-14T07:27:24+00:00

Reserve CDM blocks for writeback if the format of the output fb
is YUV. At the moment, the reservation is done only for writeback
but can easily be extended by relaxing the checks once other
interfaces are ready to output YUV.

changes in v3:
	- squash CDM disable during encoder cleanup into this change

changes in v2:
	- use needs_cdm from topology struct
	- drop fb related checks from atomic_mode_set()
