[PATCH 0/8] media: Add Lenovo Yoga Book YB1-X91 camera support

[Maurizio Casciano]

The Lenovo Yoga Book YB1-X91L exposes an OV2740 front sensor and an
OV8858 rear sensor through the Cherry Trail AtomISP.  Its firmware does
not provide enough information for the existing sensor and IPU bridge
drivers to construct the camera links.

Add the ACPI IDs and bridge data, describe the two AtomISP camera links,
support the Yoga Book sensor clocks and modes, allow explicit raw Bayer
capture, expose per-channel white-balance controls, and add the WV517S
rear-camera lens actuator.

Raw output remains opt-in and disabled by default, so existing AtomISP
users retain the current format-selection behavior.

Tested on a Lenovo Yoga Book YB1-X91L with continuous OV2740 raw capture,
OV8858 test bars and real 10-bit Bayer frames, and live white-balance
gain changes.
