This series adds basic support for the Nuvoton WPCM450 BMC SoC. It's an older SoC but still commonly found on eBay, mostly in Supermicro X9 server boards. Patches 1-6 add devicetree bindings for the WPCM450 SoC and its various parts. Patches 7-11 add arch and driver support. Patches 12 and 13 add a devicetree for the SoC and a board based on it. Patch 14 finally updates the MAINTAINERS file. Patch 2 requires "dt-bindings: arm: Convert nuvoton,npcm750 binding to YAML" (https://lore.kernel.org/lkml/20210320164023.614059-1-j.neuschaefer@xxxxxxx/) This series is based on 5.12-rc2, and doesn't cleanly apply to OpenBMC's dev-5.10 branch (there are some trivial merge conflicts).
