Subject: [PATCH v2 0/2] driver: reset: spacemit-p1: add driver for poweroff/reboot
Date: Sun, 19 Oct 2025 21:14:11 +0200 [thread overview]
Message-ID: <20251019191519.3898095-1-aurelien@aurel32.net> (raw)
This adds poweroff/reboot support for the SpacemiT P1 PMIC chip, which is
commonly paired with the SpacemiT K1 SoC.
Note: For reliable operation, this driver depends on a this patch that adds
atomic transfer support to the SpacemiT I2C controller driver:
https://lore.kernel.org/spacemit/20251009-k1-i2c-atomic-v4-1-a89367870286@linux.spacemit.com/
Changes between version 1 and version 2:
- Rebase onto v6.18-rc1
- Use dev_err_probe() to simplify the code
- Fix indentation of patch 1
- Collect Acked-by and Tested-by
Here is version 1 of this series:
