It covers the OV8858 19.2 MHz clock and Cherry Trail gain programming, OV2740 288 MHz link frequency and manual white balance, firmware IDs and IPU bridge data, AtomISP raw capture and CSI-2 timing, and the WV517S lens actuator. Changes in v6: - In patch 2, replace the arithmetic MHz expressions with direct Hz constants, as requested by Andy Shevchenko. - Give the supported input clocks distinct names: OV8858_XVCLK_FREQ_24MHZ and OV8858_XVCLK_FREQ_19_2MHZ. - No other code changes from v5. Validation: - Strict checkpatch over all 16 patches: no errors or warnings. - W=1 object build of drivers/media/i2c/ov8858.o. - Sparse C=2 check of drivers/media/i2c/ov8858.c. - Front and rear cameras previously validated on the Yoga Book with real raw Bayer capture.
