mfd: rohm: Factor out power button registration

2026-07-30T13:33:08Z

Factor out the power button registration logic using software nodes from rohm-bd718x7 and rohm-bd71828 drivers into a shared module rohm-pwrbutton. This reduces duplication and makes it easier to support other ROHM PMICs with similar power button configurations.

mfd: si476x: Modernize GPIO handling

2026-07-30T13:32:34Z

The SI476X driver depends on the legacy GPIO API. As it only really use a single GPIO for reset, and this can be easily converted to use a GPIO descriptor, modernize the driver. The "reset" GPIO is obtained from a device property, such as a device tree ("reset-gpios", which is standard, but this hardware has no DT bindings as of now) or a software node for static platforms. Out-of-tree users can easily adopt to providing a GPIO descriptor this way.

mfd: qcom: Unify user-visible "Qualcomm" name

2026-06-17T10:32:27Z

Various names for Qualcomm as a company are used in user-visible config options: QCOM, Qualcomm and Qualcomm Technologies. Switch to unified "Qualcomm" so it will be easier for users to identify the options when for example running menuconfig.

mfd: ezx-pcap: Remove unused driver

2026-06-17T10:32:14Z

Support for the Motorola EZX phones based on Intel PXA processors was removed in 2022, but this driver remained present in the tree. As far as I can tell, the support was never quite functional upstream because the board files did not actually instantiate the SPI device for the PCAP. There are still also drivers for the various mfd cells: keys, touchscreen, regulator and rtc, all of which are obviously orphaned as well but can be removed separately as the Kconfig dependency now prevents them from being enabled.

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

2026-01-22T14:23:23Z

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: rohm-bd71828: Support ROHM BD72720

2026-01-13T12:47:28Z

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.

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.
