Subject: [PATCH 00/14] Initial support for Nuvoton WPCM450 BMC SoC
Date: Sat, 20 Mar 2021 19:15:56 +0100	[thread overview]
Message-ID: <20210320181610.680870-1-j.neuschaefer@gmx.net> (raw)

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).
