[PATCH v5 3/7] arm64: dts: s32g: make pinctrl part of mfd node

There is a newer version of this series
[PATCH v5 3/7] arm64: dts: s32g: make pinctrl part of mfd node
Posted by Andrei Stefanescu 1 year, 3 months ago 
SIUL2 is now represented as an mfd device. Therefore, the old
pinctrl node is deprecated. Move the pinctrl related properties
inside the new "nxp-siul2" node. The latter one is now used
to represent the mfd device.

This will affect users of this DTS. Your commit lacks rationale for
doing this, considering its impact. Re-describing devices is really
unexpected so should come with strong arguments.

Generally, dt team want you to keep both for sometime to keep
back compatiblity.

Just to make sure I understand correctly, I will keep the previous pinctrl
node and have both the new siul2 node and the old pinctrl one, right?
