Subject: [PATCH v2 0/6] spacemit: introduce P1 PMIC and regulator support
Date: Thu, 19 Jun 2025 08:51:44 -0500 [thread overview]
Message-ID: <20250619135151.3206258-1-elder@riscstar.com> (raw)
The SpacemiT P1 is an I2C-controlled PMIC that implements six buck
converters and twelve LDOs. It contains a load switch, ADC channels,
GPIOs, a real-time clock, and a watchdog timer.
This series introduces a multifunction driver for the P1 PMIC as well
as a driver for its regulators.
This series is available here:

-Alex
Between version 1 and version 2:
- Added Reviewed-by tag from Mark Brown to patch 3
- Implemented suggestions from Vivian Wang:
- Fixed a typo in the subject line in patch 1
- Now use module_i2c_driver() for the PMIC driver in patch 2
- Added MODULE_ALIAS() for both drivers (patches 2 and 3)
- Defined and used DRV_NAME in both drivers
- Added additional Kconfig module help text for both drivers
Here is version 1 of this series:
