[PATCH 2/8] dt-bindings: soc: socionext: Add UniPhier SoC-glue logic

From: Kunihiko Hayashi
Date: Tue Nov 29 2022 - 05:35:26 EST


Add devicetree binding schema for the SoC-glue logic implemented on
Socionext Uniphier SoCs.

This SoC-glue logic is a set of miscellaneous function registers
handling signals for specific devices outside system components,
and also has multiple functions such as I/O pinmux, usb-phy, debug,
clock-mux for a specific SoC, and so on.
