mfd: cs5535: Don't build on UML

2023-03-10T08:33:28+00:00

[ Upstream commit 5ec32a3e4053c1a726b45381d56aa9e39eaf3911 ] The cs5535-mfd driver uses CPU-specific data that is not available for ARCH=um builds, so don't allow it to be built for UML.

mfd: bd957x: Fix Kconfig dependency on REGMAP_IRQ

[ Upstream commit 85842c46fd47fa6bd78681c154223bed27d5fd19 ] The BD957x driver uses REGMAP_IRQ but does not 'select' to depend on it. This can cause build failures. Select REGMAP_IRQ for BD957X.

mfd: silergy,sy7636a: Add config option MFD_SY7636A

2022-09-28T15:09:50+00:00

Add a specific MFD_SY7636A config option. As part of this change we can use MFD_SY7636A as a dependency for all SY7636a components and also remove the name from MFD_SIMPLE_MFD_I2C as it no longer needs to be selectable.

mfd: mt6370: Add MediaTek MT6370 support

2022-09-28T15:09:50+00:00

This adds support for the MediaTek MT6370 SubPMIC. MediaTek MT6370 is a SubPMIC consisting of a single cell battery charger with ADC monitoring, RGB LEDs, dual channel flashlight, WLED backlight driver, display bias voltage supply, one general purpose LDO, and the USB Type-C & PD controller complies with the latest USB Type-C and PD standards.

mfd: intel_soc_pmic_crc: Drop redundant ACPI_PTR() and ifdeffery

2022-09-28T15:09:49+00:00

The driver depends on ACPI, ACPI_PTR() resolution is always the same. Otherwise a compiler may produce a warning. That said, the rule of thumb either ugly ifdeffery with ACPI_PTR or none should be used in a driver.

mfd: ocelot: Add support for the vsc7512 chip via spi

2022-09-09T06:54:47+00:00

The VSC7512 is a networking chip that contains several peripherals. Many of these peripherals are currently supported by the VSC7513 and VSC7514 chips, but those run on an internal CPU. The VSC7512 lacks this CPU, and must be controlled externally. Utilize the existing drivers by referencing the chip as an MFD. Add support for the two MDIO buses, the internal phys, pinctrl, and serial GPIO.

mfd: sun6i-prcm: Update Kconfig description

2022-07-19T09:54:42+00:00

This driver is used by a specific range of SoCs between when the PRCM hardware was introduced (A31) and when the PRCM CCU driver was added (A83T). It is unlikely to be extended to additional hardware. Update the description to include the full list of applicable SoCs.

mfd: lpc_ich: Switch to generic p2sb_bar()

2022-07-14T09:50:25+00:00

Instead of open coding p2sb_bar() functionality we are going to use generic library. There is one more user en route. This is more than just a clean-up. It also fixes a potential issue seen when SPI BAR is 64-bit. The current code works if and only if the PCI BAR of the hidden device is inside 4G address space. In case when firmware decides to go above 4G, we will get a wrong address.
