The series landed in arm-soc and is making its way to v4.6. I guess you
can pull the original pull request. It is based on v4.5-rc1 but should
apply cleanly on v4.4:

The following changes since commit
92e963f50fc74041b5e9e744c330dca48e04f08d:

  Linux 4.5-rc1 (2016-01-24 13:06:47 -0800)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux.git
tags/at91-ab-4.6-drivers

for you to fetch changes up to 0002ca168f16e5b6ac67415a4e0198cc39af2b7f:

  clk: at91: remove useless includes (2016-02-17 17:53:04 +0100)




You may also stop at 99a81706526fb167029a940ef1f7bfbe882abd3e which
should solve the crash but it has not been tested as thoroughly.

Thanks!
