Hi, This series contains refactoring and new features implementation for the Omnivision OV4689 sensor driver. Specifically, patches 1, 2, 3, 5, 6, 10, 15, 16, 18, and 19 are refactorings, and are not supposed to introduce any functional change. Patches 4 and 7 perform migration to CCI helpers and subdevice active state respectively, and should not introduce any hardware- and/or user-visible change either. Patch 8 fixes a possible race condition due to v4l2_async_register_subdev_sensor being called too early in ov4689_probe, and patch 9 migrates power management to PM autosuspend. Patches 11-14 expose more sensor controls to the userspace, such as (read-write) HBLANK, VFLIP/HFLIP, digital gain, and color balance. Patch 17 implements configurable analogue crop rectangle via .set_selection callback. And finally, patch 20 enables 2x2 binning option. It should be noted that publicly available sensor documentation is lacking description of many registers and their value ranges, so a lot of values had to be found by experimentation. Changes in v2: - collect Laurent's r-b's - squash together "CCI conversion" and "Set gain in one 16 bit write" - use ctrl->val in ov4689_set_ctrl - rename try_fmt to fmt in ov4689_init_cfg and drop corresponding comment - rebase on top of media-stage and rename init_cfg->init_state - sort register definitions by address throughout the whole series - fix number of controls hint in v4l2_ctrl_handler_init - make all hexadecimal constants lowercase - disable runtime pm in probe error path - implement pm autosuspend Mikhail Rudenko (20): media: i2c: ov4689: Clean up and annotate the register table media: i2c: ov4689: Sort register definitions by address media: i2c: ov4689: Fix typo in a comment media: i2c: ov4689: CCI conversion media: i2c: ov4689: Remove i2c_client from ov4689 struct media: i2c: ov4689: Refactor ov4689_set_ctrl media: i2c: ov4689: Use sub-device active state media: i2c: ov4689: Enable runtime PM before registering sub-device media: i2c: ov4689: Use runtime PM autosuspend media: i2c: ov4689: Remove max_fps field from struct ov4689_mode media: i2c: ov4689: Make horizontal blanking configurable media: i2c: ov4689: Implement vflip/hflip controls media: i2c: ov4689: Implement digital gain control media: i2c: ov4689: Implement manual color balance controls media: i2c: ov4689: Move pixel array size out of struct ov4689_mode media: i2c: ov4689: Set timing registers programmatically media: i2c: ov4689: Configurable analogue crop media: i2c: ov4689: Eliminate struct ov4689_mode media: i2c: ov4689: Refactor ov4689_s_stream media: i2c: ov4689: Implement 2x2 binning drivers/media/i2c/Kconfig | 1 + drivers/media/i2c/ov4689.c | 964 +++++++++++++++++++++++-------------- 2 files changed, 592 insertions(+), 373 deletions(-) -- 2.43.0
