Add a driver for the TI DS90UB953-Q1, a MIPI CSI-2 video serializer that
forwards a MIPI CSI-2 input video stream over an FPD Link 3 connection to a
remote deserializer. It also allows access to I2C and GPIO from the
deserializer.

The commit d66acc39c7ce ("bitops: Optimise get_order()") introduced a

PAGE_SHIFT here is 16. The commit changed the get_order() to be a

Hi,
this is a second round of RFC patches to move forward on discussion about
proper kernel support for the TI DS90UB9xx serializer/deserializer chipsets

RFCv2 is a major improvement over RFCv1, with several parts rewritten from

needs to know when a slave is being
