Subject: [PATCH v2 4/4] gpio: dt-bindings: Update documentation with ast2600 controllers
Date: Thu,  5 Sep 2019 11:18:00 +1000	[thread overview]
Message-ID: <20190905011800.16156-1-rashmica.g@gmail.com> (raw)

The ast2600 is a new generation of SoC from ASPEED. Similarly to the
ast2400 and ast2500, it has a GPIO controller for it's 3.6V GPIO pins.
Additionally, it has a GPIO controller for 36 1.8V GPIO pins. These
voltages are fixed and cannot be configured via pinconf, so we have two
separate drivers for them.
