Subject: [PATCH v2 0/3] Allwinner D1 power domain support
Date: Thu, 26 Jan 2023 00:34:16 -0600 [thread overview]
Message-ID: <20230126063419.15971-1-samuel@sholland.org> (raw)
This series adds support for the power controller found in D1 and other
recent Allwinner SoCs. There is no first-party documentation, but there
are a couple of vendor drivers for different hardware revisions[1][2],
and the register definitions were easy to verify empirically.
I have tested this driver on D1 with the video engine.

[2]: https://github.com/mangopi-sbc/tina-linux-5.4/blob/main/drivers/soc/sunxi/pm_domains.c
Changes in v2:
- Removed quotes from "PPU"
- Fixed indentation in binding example
- Removed possibly misleading comment from the Kconfig description
- Include a patch adding the device tree node
