[PATCH v2 00/10] Initial support for Nuvoton WPCM450 BMC SoC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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"

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@xxxxxxx/
