Subject: [PATCH 0/6] qcom: camss: dts: Prune and tidy x13s, rb5 and rb3
 CAMSS dts

This series does a refresh on upstream x13s, rb5 and rb3 dts.

Firstly:
Moving from static dts files for the mezzanine cards to dtso.
A recent examples of this approach is here:

Commit: bc90f56a1699 ("arm64: dts: sm8650-hdk: add support for the Display Card overlay")

Taking this example this series converts rb3 and rb5 to the same overlay
format. The apq8016-sbc-d3-camera-mezzanine.dtb is omitted from this series
as I haven't had an opportunity to test on this platform but, will do so at
a later date.

Secondly:
rb3 and rb5 both declare clock-lanes in their respective sensor blocks.
Neither sensor actually requires this declaration.

Drop in both cases.

Finally:
Declare CMA heaps for both mezzanine boards so that libcamera's DMA buf
will work with upstream rb3/rb5 camera mezzanine boards.
