Arnd, Olof,

Here is the DT pull request for 4.21. The clock DT binding switch has
been in -next for a while and doesn't seem to have any issue.

This is based on the 4.20 fixes branch that you alredy pulled.

The following changes since commit 4ab7ca092c3c7ac8b16aa28eba723a8868f82f14:

  ARM: dts: at91: sama5d2: use the divided clock for SMC (2018-11-21 11:50:32 +0100)

are available in the Git repository at:

AT91 DT for 4.21

 - Switch most platforms to the new clock binding
 - Small improvement for Axentia nattis

Merged, but how does this affect downstream users who have out-of-tree DTS
files that include the SoC dtsi? Seems like lots of stuff would break.

A few may break indeed. However, there are very few clocks that are
actually exported out of the SoC (2 to 4) and they are very rarely used
(usually only one to clock an audio codec).
The other affected dts are the boards using the flexcom and my opinion
is that we should probably get the flexcom stuff back in the dtsi
anyway..

So yes, some out of tree board dts may break but they are pretty easy to
fix. Also, the DT ABI compatibility is not broken so I don't expect too
much breakage overall.
