[v3,0/7] mfd: bcm590xx: Add support for BCM59054

Add support for the BCM59054 MFD to the bcm590xx driver and fix a
couple of small bugs in it that also affected the already supported
BCM59056.

While we're at it - convert the devicetree bindings to YAML format
and drop the bcm59056 DTS in favor of describing the PMU in users'
DTS files, as is done for most other MFDs.

The BCM59054 is fairly similar to the BCM59056, with the primary
difference being the different number and layout of regulators.
It is primarily used in devices using the BCM21664 and BCM23550
chipsets.

This patchset has been tested on a Samsung Galaxy Grand Neo
(baffinlite rev02; DTS not in mainline yet) with a BCM59054 PMIC.
Testing on a BCM59056 would be appreciated.

Changes in v3:
- Split out regulator DT bindings into separate YAML
- Use tables of regulator info instead of get_XXX_register, reg_is_XXX
  functions
- Drop "regulator: bcm590xx: Add proper handling for PMMODE registers";
  it adds unnecessary noise to the series and will be submitted separately
- Link to v2: https://lore.kernel.org/r/[e-mail]

Changes in v2:
- Fixed BCM59054 ID being passed to BCM59056 function in the
  regulator driver
- Dropped linux-rpi-kernel from the CC list
- Link to v1: https://lore.kernel.org/r/[e-mail]
