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

From: Steven Lee
Date: Tue Jun 08 2021 - 06:26:24 EST


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.
