mfd: rk808: Make MFD_RK8XX tristate

2023-09-13T07:53:47+00:00

[ Upstream commit d085c27aa62999e2fe054707ab9da2af65d22b2f ] There is no reason for MFD_RK8XX to be bool, all drivers that depend on it, or that select it, are tristate.

mfd: max77541: Add ADI MAX77541/MAX77540 PMIC Support

2023-06-21T17:16:18+00:00

MFD driver for MAX77541/MAX77540 to enable its sub devices. The MAX77541 is a multi-function devices. It includes buck converter and ADC. The MAX77540 is a high-efficiency buck converter with two 3A switching phases. They have same regmap except for ADC part of MAX77541.

mfd: max5970: Rename driver and remove wildcard

2023-06-02T08:09:45+00:00

The previous version of this driver included wildcards in file names and descriptions. This patch renames the driver to only support MAX5970 and MAX5978, which are the only chips that the driver actually supports.

mfd: tps6594: Add driver for TI TPS6594 PMIC

2023-05-18T15:06:14+00:00

This patch adds support for TPS6594 PMIC MFD core. It provides communication through the I2C and SPI interfaces, and supports protocols with embedded CRC data fields for safety applications.

mfd: rk8xx: Add rk806 support

2023-05-15T15:20:22+00:00

Add support for SPI connected rk806, which is used by the RK3588 evaluation boards. The PMIC is advertised to support I2C and SPI, but the evaluation boards all use SPI. Thus only SPI support is added here.

mfd: Add Renesas RZ/G2L MTU3a core driver

2023-04-26T10:40:34+00:00

The RZ/G2L multi-function timer pulse unit 3 (MTU3a) is embedded in the Renesas RZ/G2L family SoCs. It consists of eight 16-bit timer channels and one 32-bit timer channel. It supports the following functions - Counter - Timer - PWM The 8/16/32 bit registers are mixed in each channel. Add MTU3a core driver for RZ/G2L SoC. The core driver shares the clk and channel register access for the other child devices like Counter, PWM and Clock event.

mfd: max597x: Add support for MAX5970 and MAX5978

2023-04-26T10:40:29+00:00

Implement a regulator driver with IRQ support for fault management. Written against documentation [1] and [2] and tested on real hardware. Every channel has it's own regulator supply nammed 'vss1-supply' and 'vss2-supply'. The regulator supply is used to determine the output voltage, as the smart switch provides no output regulation. The driver requires the 'shunt-resistor-micro-ohms' to be present in the devicetree to properly calculate current related values. You must specify compatible devictree layout: regulator@3a { reg = <0x3a>; vss1-supply = <&p3v3>; compatible = "maxim,max5978"; ... regulators { sw0_ref: SW0 { regulator-compatible = "SW0"; shunt-resistor-micro-ohms = <12000>; ... } } } 1: https://datasheets.maximintegrated.com/en/ds/MAX5970.pdf 2: https://datasheets.maximintegrated.com/en/ds/MAX5978.pdf ... Changes in V12: - Use simple_mfd_i2c driver and remove previous implementation. - Remove newline - Use _MFD_MAX597X_H in header file - Successfull build need following patch from regulator: https://lore.kernel.org/r/20230216075302.68935-1-Naresh.Solanki@9elements.com https://lore.kernel.org/r/20230210163225.1208035-1-Naresh.Solanki@9elements.com Signed-off-by: Patrick Rudolph Signed-off-by: Marcello Sylvester Bauer Signed-off-by: Naresh Solanki Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20230307121246.127425-2-Naresh.Solanki@9elements.com
