Subject: [PATCH 0/6] spacemit: introduce P1 PMIC and regulator support
Date: Fri, 13 Jun 2025 16:01:43 -0500	[thread overview]
Message-ID: <20250613210150.1468845-1-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:
