Subject: [PATCH 0/2] Add Realtek Otto GPIO support
Date: Mon, 15 Mar 2021 09:23:38 +0100	[thread overview]
Message-ID: <20210315082339.9787-1-sander@svanheule.net> (raw)

Add support for the GPIO controller employed by Realtek in multiple series of
MIPS SoCs. These include the supported RTL838x and RTL839x series.
The register layout also matches the one found in GPIO controllers of
other (Lexra-based) SoCs such as RTL8196E, RTL8197D, and RTL8197F.

For the platform name 'otto', I am not aware of any official resources as to
what hardware this specifically applies to. However, in all of the GPL archives
we've received, from vendors using compatible SoCs in their design, the
platform under the MIPS architecture is referred to by this name.

The GPIO ports have been tested on a Zyxel GS1900-8 (RTL8380M), and
Zyxel GS1900-48 (RTL8393M). Furthermore, the GPIO ports and interrupt
controller have been tested on a Netgear GS110TPPv1 (RTL8381M).
