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

2026-01-22T14:23:23+00:00

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: Kconfig: Default MFD_SPACEMIT_P1 to 'm' if ARCH_SPACEMIT

2026-01-22T14:23:13+00:00

The default value of the P1 sub-device depends on the value of P1, so P1 should have a default value here. Signed-off-by: Troy Mitchell Acked-by: Alex Elder Link: https://patch.msgid.link/20251225-p1-kconfig-fix-v4-2-44b6728117c1@linux.spacemit.com Signed-off-by: Lee Jones

mfd: rohm-bd71828: Support ROHM BD72720

2026-01-13T12:47:28+00:00

The ROHM BD72720 is a power management IC which continues the BD71828 family of PMICs. Similarly to the BD71815 and BD71828, the BD72720 integrates regulators, charger, RTC, clock gate and GPIOs. The main difference to the earlier PMICs is that the BD72720 has two different I2C slave addresses. In addition to the registers behind the 'main I2C address', most of the charger (and to some extent LED) control is done via registers behind a 'secondary I2C slave address', 0x4c.

mfd: Kconfig: Drop OF dependency on MFD_MAX5970

2025-11-19T15:39:11+00:00

This is the only Kconfig symbol that depends on OF while selecting the common driver for several chips. Drop this unneeded dependency and make the component available on non-OF systems along with wider compile test.

mfd: simple-mfd-i2c: Remove select I2C_K1 from MFD_SPACEMIT_P1

2025-11-06T16:03:41+00:00

select will force a symbol to a specific value without considering its dependencies. As a result, the i2c-k1 driver will fail to build when OF or COMMON_CLK are disabled. The reason for removing I2C_K1 instead of adding a depends on condition is to keep the possibility for other SoCs to use this PMIC.
