[PATCH v6 0/4] convert rockchip,dwc3.txt to yaml

The conversion of rockchip,dwc3.txt to yaml was added to linux-next,
but the necessary changes for rk3399 are still pending.

For rk3399 dwc3 usb the wrapper node for only clocks makes no sense,
so that was removed in the YAML example.

Now dtbs_check still generates notifications for the compatibility string in
the dts files that doesn't match, because it changed from
"rockchip,rk3399-dwc3" to "rockchip,rk3399-dwc3", "snps,dwc3".

The problem is to keep compatible with old device trees.
I.e. a device running an older device tree should still work with newer
kernels.

Comment by Rob in version 3:
Presumably you are getting lucky here (with link order). The kernel
has no logic to decide which driver to bind to if there are 2 matching
drivers. If we did, it would probably be the opposite of what you want
here as we'd pick the most specific match. This driver should probably
bail probe if no dwc3 child node.

Please advise how to move forward with this serie.
