[PATCH v7 00/19] Small fixes and cleanups (ov2740 and ccs)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi folks,

This small set contains fixes and cleanups, mainly for the ccs and ov2740
drivers. I wrote these while working on the metadata set, but these could
and should be merged earlier.

since v6:

- New patch: In scope of the CCS driver, revert the patch moving CCS to
  use pm_runtime_get_and_resume().

- New patch: Drop s_stream re-entrancy in CCS driver.

- New patch: Rename ccs_create_subdev() as ccs_init_subdev.

- New patch: CCS driver rework: move sub-device initialisation earlier in
  probe to address initialisation ordering issues later on in embedded
  data support. This introduces minor changes to the patch adding
  sub-device state support.

since v5:

- Send right patches (was v3 + an additional patch)!

since v4:

- Fix CCS driver active state patch --- media entity was initialised too
  late.

- Rebase on Laurent's ov2740 cleanups.

- Add a new patch for MIPI CSI-2 long packet types.

since v3:

- Don't print frame descriptor entry flags as strings but in a numeric
  form.

- Add a WARN_ON() for string truncation in printing the frame descriptor.

- Use 0 flag in printing hexadecimal values in frame descriptor instead of
  specifying precision.

- Add curly braces around a loop (11th patch).

since v2:

- Wrap init_cfg callback long line.

- Remove "pad_" from variable names in ccs_init_cfg.

- Fix media_entity_pads_init() error handling bug (was introduced in the
  last patch).

- Print frame descriptor in less verbose way.

since v1:

- Add a comment on ov2740 active state patch on serialising sensor access.

- Improved commit message of ov2740 patch enabling runtime PM earlier.

- Added patches for printing and zeroing frame descriptor, (debug)
  printing of frame descriptor, switching ccs to init_cfg and sub-device
  state and checking pad flag validity.
