Hi Ryan,

Thanks for the patch. I have a few comments:

Generally if we're listing things the patch does in the commit message 
it's a sign that the commit should be split up.

Can you please fix up your git config so your name is capitalised and 
to switch the underscore to a space? For example:

git config --global user.name 'Ryan Chen'

You might need to amend the commit and replace the S-o-B tag above.

Can we tack the description on as per the datasheet, like the others?

#define SCU470	0x470 /* Multi-function Pin Control */

It doesn't have a number assigned in my v13 copy of the datasheet, but 
oh well.

This one isn't documented at all in v13. What is its purpose?

The ordering of these in the datasheet gets me every time :(

I'm mildly concerned that this appears in the pinmux driver...

Bits 15:0 are marked as 'Reserved' in the v13 datasheet. Can we please 
get them documented?

Further, this is a new constraint on an existing function. Can we 
please split this out into its own patch to limit the context for 
review?

We don't need this as SCU410[28] is cleared as part of disabling NCTS3.

As above.

What is SCU470[16] actually doing? The documentation only defines it in 
terms of what it disables and doesn't explain why. Under what 
conditions would this bit need to be set? When we want to use the pin 
as GPIO? Something else?

Until that's answered I'll hold off on commenting on how we should be 
describing it here.

This is cleared by disabling the MTCK signal, so no need to specify 
SIG_DESC_CLEAR(SCU418, 2) here.

Can you please split the Secure I2C changes out into a separate patch?

This one seems legitimate. I'm wondering if what we need is a better 
approach to the short-circuit expression evaluation, something between 
my original short-circuit at first opportunity and Billy's never 
short-circuit approach. It almost feels like we need groups that are 
always configured in certain ways.

That or we split the enable and disable paths up properly and not 
assume the inverse of enable is enough.

Same query. Changing this requires changing the mux state specification 
in the platform devicetree, which means any existing consumers will 
break, right?

SCU438[20] is already cleared by disabling I3C3SCL.

Doesn't this only expose the device on PCIe? Why is this a problem for 
pinmux?

Please split this out into a separate patch so we can debate it 
separately.

DMA configuration doesn't sound like the responsibility of a pinctrl
