[PATCH v2 0/3] dt-bindings: Add macros for video interface bus types

Hello,

This small patch series is the result of me getting a bus-type numerical
value wrong in a device tree file and spending too long debugging the
issue. Hopefully there's nothing controversial here.

Compared to v1, the PARALLEL bus type has been renamed to BT601, and
patch 3/3 now converts existing DT sources. See individual patches for a
detailed changelog.

I can split patch 3/3 per architecture or per board if desired, but
given that this is a mechanical change, and the patch is fairly small,
I'd rather keep it as-is and merge it as part of the series.

When writing 3/3 I noticed that the anx7625 bindings and the
corresponding driver badly misuse the bus type (mapping CCP2 to mean
MIPI DPI, and PARALLEL - now BT601 - to mean MIPI DSI). This misuse
hasn't reached a released mainline kernel as it got merged in v5.17-rc1,
so there may still be a chance to fix it. Let's discuss this in [1],
I'll update this series and rebase it on v5.18-rc1 once released based
on the outcome of the discussion.
