Subject: [PATCH 11/12] riscv: dts: allwinner: Add ClockworkPi and DevTerm devicetrees
Date: Mon, 15 Aug 2022 00:08:14 -0500 [thread overview]
Message-ID: <20220815050815.22340-12-samuel@sholland.org> (raw)
In-Reply-To: <20220815050815.22340-1-samuel@sholland.org>
Clockwork Tech manufactures several SoMs for their RasPi CM3-compatible
"ClockworkPi" mainboard. Their R-01 SoM features the Allwinner D1 SoC.
The R-01 contains only the CPU, DRAM, and always-on voltage regulation;
it does not merit a separate devicetree.
The ClockworkPi mainboard features analog audio, a MIPI-DSI panel, USB
host and peripheral ports, an Ampak AP6256 WiFi/Bluetooth module, and an
X-Powers AXP228 PMIC for managing a Li-ion battery.
The DevTerm is a complete system which extends the ClockworkPi mainboard
with a pair of expansion boards. These expansion boards provide a fan, a
keyboard, speakers, and a thermal printer.
