This is the seventh version of the OV5645 camera sensor driver patchset. Changes since version 6 include: - keep a pointer to the current sensor mode and remove enum ov5645_mode; - do not keep v4l2 control values and xclk frequency in the main data struct; - add caching variables in then main data struct for some of the register values to avoid i2c read commands; - use reference counting for power state; - enable xclk only after regulators are enabled; - add check for xclk rate that it is supported; - register v4l2 subdev only at the end of probe when the rest is succeeded; - add hardware pin names in gpio descriptions in the dt binding document; - other minor changes: uppercase to lowercase, add const modifier, remove unnecessary local variables, fix return values. Changes since version 5 include: - external clock frequency set in DT; - added v4l2_subdev_pad_ops.init_cfg function to initialize formats; - current sensor mode not updated if set_fmt is TRY (not ACTIVE); - other small changes - debug messages removed, register addresses defines renamed, redundant safety checks removed, unnecessary labels removed, mutex_destroy added. Two one-line changes since version 4: - return current format on set_format; - return all frame sizes when enumerating them. Only one change since version 3: - build failure on kernel v4.7-rc1 fixed: s/media_entity_init/media_entity_pads_init/ Changes from version 2 include: - external camera clock configuration is moved from DT to driver; - pwdn-gpios renamed to enable-gpios; - switched polarity of reset-gpios to the more intuitive active low; - added Kconfig dependency to OF; - return values checks; - regulators and gpios are now required (not optional); - regulators names renamed; - power counter variable changed to a bool power state; - ov5645_registered() is removed and sensor id reading moved to probe(). Changes from version 1 include: - patch split to dt binding doc patch and driver patch; - changes in power on/off logic - s_power is now not called on open/close; - using assigned-clock-rates in dt for setting camera external clock rate; - correct api for gpio handling; - return values checks; - style fixes.
