[PATCH 0/3] V4L2 API for flash devices and the adp1653 flash controller driver

[Sakari Ailus <sakari.ailus@maxwell.research.nokia.com>]

Hi,


This patchset implements RFC v4 of V4L2 API for flash devices [1], with
minor modifications, and adds the adp1653 flash controller driver.

This patchset depends on the bitmask controls patch [4].

Changes since v2 [3] of the RFC patchset:

- Improved flash control documentation in general.

- Faults may change the LED mode to none. This is now documented.

- adp1653 is returned to sane after faults are detected.

- Proper error handling for adp1653_get_fault() in adp1653_strobe().

- Remove useless function: adp1653_registered() and the corresponding
  callback. Controls are now initialised in adp1653_probe().

- Improved fault handling in adp1653_init_device().

Changes since v1 [2] of the RFC patchset:

- Faults on the flash LED are allowed to make the LED unusable before
the faults are read. This is implemented in the adp1653 driver.

- Intensities are using standard units; mA for flash / torch and uA for
the indicator.


Thanks to those who have given their feedback so far in the process!
