[PATCH v5 02/10] dt-bindings: aspeed-sgpio: Add ast2600 sgpio compatibles.

From: Steven Lee <hidden>
Date: 2021-06-08 10:26:07
Also in: linux-aspeed, linux-devicetree, linux-gpio, lkml
Subsystem: gpio subsystem, open firmware and flattened device tree bindings, the rest · Maintainers: Linus Walleij, Bartosz Golaszewski, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

AST2600 SoC has 2 SGPIO master interfaces one with 128 pins another one
with 80 pins. Add ast2600-sgpiom0-80 and ast2600-sgpiom-128 compatibles
and update descriptions to introduce the max number of available gpio
pins that AST2600 supported.
