mfd: bcm590xx: Drop unused "id" member of bcm590xx struct

2025-05-23T07:48:08+00:00

The "id" member of the bcm590xx struct is unused and will be confusing once we add an actual PMU ID storage value. Drop it; a replacement will be introduced in a future commit.

regulator: bcm590xx: Store regulator descriptions in table

2025-05-22T09:57:26+00:00

Instead of filling in the regulator description programatically, store the data in a struct. This will make it a bit nicer to introduce support for other BCM590xx chips besides the BCM59056. To do this, add a new struct type, bcm590xx_reg_data, to store all of the necessary information. Drop the old IS_LDO, IS_GPLDO... macros in favor of the "type" field in this struct. Adapt the old bcm590xx_reg struct to the new types.

mfd: bcm590xx: Add PMU ID/revision parsing function

2025-05-22T09:57:00+00:00

The BCM590xx PMUs have two I2C registers for reading the PMU ID and revision. The revision is useful for subdevice drivers, since different revisions may have slight differences in behavior (for example - BCM59054 has different regulator configurations for revision A0 and A1). Check the PMU ID register and make sure it matches the DT compatible. Fetch the digital and analog revision from the PMUREV register so that it can be used in subdevice drivers. Also add some known revision values to bcm590xx.h, for convenience when writing subdevice drivers.

mfd: bcm590xx: Add support for multiple device types + BCM59054 compatible

2025-05-22T09:56:49+00:00

The BCM59054 is another chip from the BCM590xx line of PMUs, commonly used on devices with the BCM21664/BCM23550 chipsets. Prepare the BCM590xx driver for supporting other devices by adding the PMUID register values for supported chip types and store them in the MFD data struct as "pmu_id". (These will be checked against the actual PMUID register values in a later commit.) Then, add a DT compatible for the BCM59054, and provide the PMU ID as OF match data.

mfd: bcm590xx: Add support for secondary I2C slave address

2014-05-21T09:40:08+00:00

BCM590xx utilizes a secondary I2C slave address to access additional register space. Add support for the secondary address space by instantiating a dummy I2C device with the appropriate secondary I2C slave address. Also expose a secondary regmap register space so that MFD drivers can access this secondary i2c slave address space. Signed-off-by: Matt Porter Signed-off-by: Lee Jones
