Subject: [PATCH 00/12] riscv: Allwinner D1 platform support

This series adds the Kconfig/defconfig plumbing and devicetrees for a
range of Allwinner D1-based boards. Many features are already enabled,
including USB, Ethernet, and WiFi.

The SoC devicetree uses bindings from the following series which have
not yet been merged:
- SRAM controller:
  https://lore.kernel.org/lkml/20220815041248.53268-1-samuel@sholland.org/
- NVMEM cell bits property change:
  https://lore.kernel.org/lkml/20220814173656.11856-1-samuel@sholland.org/
- In-package LDO regulators:
  https://lore.kernel.org/lkml/20220815043436.20170-1-samuel@sholland.org/

All three of these are required to set the correct I/O domain voltages
in the pin controller, which I would consider important to have in the
initial version of the devicetree.

The SoC devicetree does contain one small hack to avoid a dependency on
the audio codec binding, since that is not ready yet: the codec node
uses a bare "simple-mfd", "syscon" compatible.
