Subject: [PATCH 00/14] Initial support for Nuvoton WPCM450 BMC SoC

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@gmx.net/)

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).

Jonathan Neuschäfer (14):
  dt-bindings: vendor-prefixes: Add Supermicro
  dt-bindings: arm: npcm: Add nuvoton,wpcm450 compatible string

  dt-bindings: timer: nuvoton,npcm7xx: Add wpcm450-timer
  dt-bindings: watchdog: npcm: Add nuvoton,wpcm450-wdt
  ARM: npcm: Introduce Nuvoton WPCM450 SoC
  irqchip: Add driver for WPCM450 interrupt controller
  serial: 8250_of: Add nuvoton,wpcm450-uart
