These properties have been in the samsung pinctrl driver since it was
upstreamed by Linaro in 2012 :) They are used for pin function and
pull up/down config in power down mode. See also

That is actually how it was in the first submission. The review
feedback was not to do that and have a dedicated gs101 header.

That is correct, it boot loops failing to find the ect node in the

parameter_address and parameter_size properties but the empty ect
node needs to be present to boot the kernel.

It is a 36bit address bus, but I can add a ranges property to map the
addresses and then use address-cells 1.
So will fix in v5.

Yes it is part of a USI block. I will update this in v5.

I deliberately left the clocks out for now. As APM has it's own
firmware, mailbox I want to get more information on which entity is
meant to be managing these clocks.

You were correct. fyi I fixed this in v4.

The nodes under SoC are ordered by reg address, which IIRC was
requested in earlier review feedback.
