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.
