mfd: ti_am335x_tscadc: Fix TI SoC dependencies

2024-02-23T07:42:13+00:00

[ Upstream commit 284d16c456e5d4b143f375b8ccc4038ab3f4ee0f ] The ti_am335x_tscadc is specific to some TI SoCs, update the dependencies for those SoCs and compile testing.

mfd: mp2629: Select MFD_CORE to fix build error

mfd: MFD_SL28CPLD should depend on ARCH_LAYERSCAPE

2020-12-30T10:53:16+00:00

[ Upstream commit de1292817cf736c04fab31903a6aa9d9ffe60b79 ] Currently the Kontron sl28cpld Board Management Controller is found only on Kontron boards equipped with a Freescale Layerscape SoC. Hence add a dependency on ARCH_LAYERSCAPE, to prevent asking the user about a driver for this controller when configuring a kernel without Layerscape support.

mfd: intel-m10-bmc: Add Intel MAX 10 BMC chip support for Intel FPGA PAC

2020-09-30T16:46:21+00:00

This patch implements the basic functions of the BMC chip for some Intel FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the Intel MAX 10 CPLD. This BMC chip is connected to the FPGA by a SPI bus. To provide direct register access from the FPGA, the "SPI slave to Avalon Master Bridge" (spi-avmm) IP is integrated in the chip. It converts encoded streams of bytes from the host to the internal register read/write on the Avalon bus. So This driver uses the regmap-spi-avmm for register accessing.

mfd: ene-kb3930: Add driver for ENE KB3930 Embedded Controller

2020-09-30T15:24:54+00:00

This driver provides access to the EC RAM of said embedded controller attached to the I2C bus as well as optionally supporting its slightly weird power-off/restart protocol. A particular implementation of the EC firmware can be identified by a model byte. If this driver identifies the Dell Ariel platform, it registers the appropriate cells.

mfd: simple-mfd-i2c: Add sl28cpld support

2020-09-17T14:57:26+00:00

Add the core support for the board management controller found on the SMARC-sAL28 board. 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. At the moment, this controller is used on the Kontron SMARC-sAL28 board. Signed-off-by: Michael Walle Signed-off-by: Lee Jones

mfd: Add simple regmap based I2C driver

2020-09-17T14:56:58+00:00

There are I2C devices which contain several different functions but doesn't require any special access functions. For these kind of drivers an I2C regmap should be enough. Create an I2C driver which creates an I2C regmap and enumerates its children. If a device wants to use this as its MFD core driver, it has to add an individual compatible string. It may provide its own regmap configuration. Subdevices can use dev_get_regmap() on the parent to get their regmap instance. Signed-off-by: Michael Walle Signed-off-by: Lee Jones
