The MIPI DSI PHY controller on Allwinner R40 is similar
on the one on A31.

Add R40 compatible and append A31 compatible as fallback.

This isn't doing what you say it does.

Here you're stating that there's two valid values, one that is a
single element allwinner,sun6i-a31-mipi-dphy, and another which is a
list of three elements allwinner,sun8i-r40-mipi-dphy,
allwinner,sun50i-a64-mipi-dphy and allwinner,sun6i-a31-mipi-dphy, in
that order.

I got it Maxime, thanks for pointing this.

Did you run make dtbs_check and dt_bindings_check?

I sure I didn't, thanks for the clue.

Will do this on another patch as well.

Jagan.
