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

Removing these leaves the AC97 support as ALSA specific, no other drivers are now connected through this interface.

mfd: intel-m10-bmc: Add PMCI driver

2023-01-27T10:47:11+00:00

Add the mfd driver for the Platform Management Component Interface (PMCI) based interface of Intel MAX10 BMC controller. PMCI is a software-visible interface, connected to card BMC which provided the basic functionality of read/write BMC register. The access to the register is done indirectly via a hardware controller/bridge that handles read/write/clear commands and acknowledgments for the commands. Previously, intel-m10-bmc provided sysfs under /sys/bus/spi/devices/... which is generalized in this change because not all MAX10 BMC appear under SPI anymore.
