[PATCH 1/4] dt-bindings: mfd: syscon: Add ti,am654-icssg-ctrl compatible

[Andrew Davis]

Add TI ICSSG control registers compatible. This is a region found in the
TI AM65 CTRL_MMR0 register space[0]. Each instance is used to control a
an ICSSG's RGMII delay and GPO mode.

Can be or is? Please describe the hardware what do you have there.

Drop syscon, unless this is system controller because in such case drop
ethernet-mac.

This device (parent) is a syscon already. There is no sub-block
representation, because what would be next? Third child with a node per
each register?

Actually considering my comment on the previous patch - drop.

Drop, regions are not described in DTS.

Considering your patch #2 adding something with similar name, this is
quite confusing.

Anyway, where is any user of this? If there is no user, then why? If
there is, then commit msg should explain that you document existing
device.
