   4 Subject: [PATCH 033/117] riscv: dts: allwinner: Add ClockworkPi and DevTerm
   5  devicetrees
   6
   7 Clockwork Tech manufactures several SoMs for their RasPi CM3-compatible
   8 "ClockworkPi" mainboard. Their R-01 SoM features the Allwinner D1 SoC.
   9 The R-01 contains only the CPU, DRAM, and always-on voltage regulation;
  10 it does not merit a separate devicetree.
  11
  12 The ClockworkPi mainboard features analog audio, a MIPI-DSI panel, USB
  13 host and peripheral ports, an Ampak AP6256 WiFi/Bluetooth module, and an
  14 X-Powers AXP228 PMIC for managing a Li-ion battery.
  15
  16 The DevTerm is a complete system which extends the ClockworkPi mainboard
  17 with a pair of expansion boards. These expansion boards provide a fan, a
  18 keyboard, speakers, and a thermal printer.
