Subject: [PATCH 0/2] power: regulator: add AXP717 support
Date: Fri, 10 May 2024 00:43:17 +0100 [thread overview]
Message-ID: <20240509234319.13104-1-andre.przywara@arm.com> (raw)
The X-Powers AXP717 is a PMIC chip, controlled via I2C or RSB. It
features four DC/DC converters and a number of linear regulators.
Also it contains some charger and USB-C detection circuitry, though we
don't use that in U-Boot. The PMIC is used on some newer Allwinner
devices, for instance the Anbernic handheld gaming devices.
Add AXP717 support to the DM driven AXP regulator driver, and also an SPL
version, as we need to program the DRAM voltage rail correctly before
attempting to initialise the DRAM controller.
Cheers,
Ander
