mfd: axp20x: AXP717: Add AXP717_TS_PIN_CFG to writeable regs

2025-02-20T16:05:09Z

Add AXP717_TS_PIN_CFG (register 0x50) to the table of writeable registers so that the temperature sensor can be configured by the battery driver. Signed-off-by: Chris Morgan Link: https://lore.kernel.org/r/20250204155835.161973-3-macroalpha82@gmail.com Signed-off-by: Lee Jones

mfd: axp20x: Add support for AXP323

2024-10-31T15:51:29Z

The X-Powers AXP323 is a very close sibling of the AXP313A. The only difference seems to be the ability to dual-phase the first two DC/DC converter, which adds another register. Add the required boilerplate to introduce a new PMIC to the AXP MFD driver. Where possible, this just maps into the existing structs defined for the AXP313A, only deviating where needed.

mfd: axp20x: Ensure relationship between IDs and model names

2024-10-31T15:51:20Z

At the moment there is an implicit relationship between the AXP model IDs and the order of the strings in the axp20x_model_names[] array. This is fragile, and makes adding IDs in the middle error prone. Make this relationship official by changing the ID type to the actual enum used, and using indexed initialisers for the string list.

regulator: axp20x: AXP717: Add boost regulator

2024-09-06T21:17:36Z

The AXP717 also contains an adjustable boost regulator, to provide the 5V USB VBUS rail when running on battery. Add the regulator description that states the voltage range this regulator can cover.

regulator: axp20x: add support for the AXP717

2024-03-28T09:51:03Z

The X-Powers AXP717 is a typical PMIC from X-Powers, featuring four DC/DC converters and 15 LDOs, on the regulator side. Describe the chip's voltage settings and switch registers, how the voltages are encoded, and connect this to the MFD device via its regulator ID.

The AXP717a is a PMIC chip produced by X-Powers, it can be connected to an I2C or RSB bus. It's a rather complete PMIC, with many regulators, interrupts, an ADC and battery charging functionality. It also offer USB type-C CC pin handling. Describe the regmap and the MFD bits, along with the registers exposed via I2C or RSB. This covers the regulator, interrupts and power key devices for now. Advertise the device using the new compatible string.
