Subject: [PATCH v2 00/10] 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.

Third-party documentation is available at: https://github.com/neuschaefer/wpcm450/wiki

Patches 1-4 add devicetree bindings for the WPCM450 SoC and its various parts.
Patches 5-7 add arch and driver support. Patches 8 and 9 add a devicetree for
the SoC and a board based on it. Patch 10 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/)


v2:
- Various improvements to the AIC irqchip driver, thanks to Marc Zyngier's review
- I dropped the timer patches, which have been applied by Daniel Lezcano
- I dropped the serial patches, which have been applied to tty-next by Greg KH

v1:
- https://lore.kernel.org/lkml/20210320181610.680870-1-j.neuschaefer@gmx.net/
