Subject: [PATCH 0/4] ov08x40: Enable use of ov08x40 on Qualcomm X1E80100
 CRD

This series brings fixes and updates to ov08x40 which allows for use of
this sensor on the Qualcomm x1e80100 CRD but also on any other dts based
system.

Firstly there's a fix for the pseudo burst mode code that was added in
8f667d202384 ("media: ov08x40: Reduce start streaming time"). Not every I2C
controller can handle an arbitrary sized write, this is the case on
Qualcomm CAMSS/CCI I2C sensor interfaces which limit the transaction size
and communicate this limit via I2C quirks. A simple fix to optionally break
up the large submitted burst into chunks not exceeding adapter->quirk size
fixes.

Secondly then is addition of a yaml description for the ov08x40 and
extension of the driver to support OF probe and powering on of the power
rails from the driver instead of from ACPI.

Once done the sensor works without further modification on the Qualcomm
x1e80100 CRD.
