[PATCH] dt-bindings: pinctrl: samsung: Require clocks for Exynos9610 pinctrl nodes

[Alexandru Chimac]

All Exynos9610 pin controllers (except PINCTRL_TOP) have clocks assigned
to them, so force the nodes to have clocks assigned to them.

Most Samsung Exynos9610 pin controllers (except TOP) have clocks
designated for them, so allow the device tree node to include clock
information for the driver.

Sorry for the spam, I had some issues with the mail host but they're all
fixed now.

I don't understand above. It's contradictory to commit msg which says
ALL. Here you say most.


Why two commit msgs?

that's ABI break without reason.

On Exynos9610, only TOP pinctrl doesn't have a clock (as far as I'm
aware; haven't found a clock for it), while the rest of the pin controller
blocks do.

The first message is the commit message, and the second one is the b4
cover message. I wasn't actually sure how b4 handles that.

AFAIK there are no (publicly available) users of this device, so this
change shouldn't break any currently available device trees.

The best (most correct imo) implementation would be having the clock
properties be optional, pin controllers for Exynos9610 don't need
to be controlled by Linux for suspend/restore (change is more for
information(?) correctness anyway), since the CMUs should have HWACG
enabled anyway.
