To make things easier to test, I pushed out a test branch with
all the pending dependencies :)

It's basically v5.3 + ti-sysc changes in Linux next, and
the following patches posted by Tero:

[PATCHv5 00/10] soc: ti: add OMAP PRM driver (for reset)
[PATCHv3 00/10] clk: ti: remoteproc / iommu support patches
[PATCH 00/10] ARM: dts: omap changes for IOMMU / reset support

And then finally the $subject patch applied on top, and the
tests above still work for me.

The test branch is test-pending-ti-sysc-clkctrl-rstctrl-v5.3
at [0] and [1] below.

Can you please test and see if that works for you?

Regards,

Tony
