mfd: simple-mfd-i2c: Add Delta TN48M CPLD support

2026-03-04T12:20:12+00:00

[ Upstream commit 8f34c1a64c5394d2b51d3fba197947dc4b0b48a0 ] Delta TN48M switches have a Lattice CPLD that serves multiple purposes including being a GPIO expander. So, lets use the simple I2C MFD driver to provide the MFD core. Also add a virtual symbol which pulls in the simple-mfd-i2c driver and provide a common symbol on which the subdevice drivers can depend on.

mfd: simple-mfd-i2c: Add SpacemiT P1 support

2026-03-04T12:20:11+00:00

[ Upstream commit 6fc5d415c10e98ac1b31dd1d5653443e691cdcff ] Enable support for the RTC and regulators found in the SpacemiT P1 PMIC. Support is implemented by the simple I2C MFD driver. The P1 PMIC is normally implemented with the SpacemiT K1 SoC. This PMIC provides 6 buck converters and 12 LDO regulators. It also implements a switch, watchdog timer, real-time clock, and more. Initially its RTC and regulators are supported.

The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed for portable applications. It provides a high dynamic range, stereo DAC for headphone output, two integrated Class D amplifiers for loudspeakers, and two ADCs for wired headset microphone input or stereo line input. PDM inputs are provided for digital microphones. The MFD component registers and initialises the device and provides PM/system power management.
