[PATCH v3 1/7] dt-bindings: media: nxp: Add support for FSD SoC

Hi Rob,

Thanks for the review

The Tesla FSD Soc does not have a dedicated reset controller. Instead, we
are using the
system controller which is MMIO Space handled by syscon driver, to assert or
de-assert the D-PHY
reset. So, I prefer to use syscon.

Sure, I'll add new patch in next patchset.

Sure, I'll add new patch in next patchset.

Will remove in nextpatchset.

According to v4.3 manual it is DMA clock.
