Subject[PATCH v2 0/4] Qualcomm Camera Control Interface driver
Date
This patchset adds basic support for the Qualcomm Camera Control Interface
(CCI) controller found on Qualcomm MSM8916/APQ8016 and MSM8996/APQ8996 SoC.

CCI has one I2C bus on MSM8916/APQ8016 and two I2C busses on MSM8996/APQ8096.
The present driver supports the first I2C bus only.

The driver is implemented using as a reference the Qualcomm CCI driver
for Android as found in Code Aurora [1] and [2].

The driver is tested on Dragonboard 410c (APQ8016) and Dragonboard 820c
(APQ8096) with one and two OV5645 camera sensors.

--------------------------------------------------------------------------------

Changes in v2:
- use clock bulk API for clock handling;
- remove reg and interrupt names from dt binding as there are only one from
each;
- improved checks in cci_validate_queue();
- halt and reset CCI on timeout after run queue;
- a fix for CCI reset after halt;
- a lot of small code and style fixes.
