PMICs. Changes in V8: 1. Introduce a helper function 'flcdev_to_qcom_fled()'. 2. Rename 'struct qcom_flash_chip' as 'struct qcom_flash_data' and remove 'qcom_flash_led' data pointers from it to avoid interwoven reference. Also remove the 'dev' pointer. 3. Remove 'v4l2_flash' data pointer in 'struct qcom_flash_led' and move it to 'struct qcom_flash_data'. Changes in V7: 1. Fix compilation issue reported by kernel test robot Changes in V6: 1. Update the driver to address review comments from Jones,Lee. Changes in V5: 1. Add MODULE_DEVICE_TABLE for auto-loading. Changes in V4: 1. Added Tested-By tag. 2. Addressed review comments in the binding change and added Reviewed-by tag. Changes in V3: 1. Updated the driver to use regmap_field for register access. 2. Adressed the review comments in binding document change. Changes in V2: 1. Addressed review comments in binding change, thanks Krzysztof! 2. Updated driver to address the compilation issue reported by kernel test robot.
