Subject: [PATCH v2 0/6] 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.

I'd appreciate testing on BCM59056-equipped boards to make sure
they aren't affected negatively by the changes. So far, I've
tested this patch series on a Samsung Galaxy Grand Neo (BAFFINLITE
REV02) with a BCM23550 chipset (BCM59054 MFD); this device is not
yet supported in the mainline kernel, but I'm working on adding
support for it, and other commercially-available devices using
Broadcom Kona chips. Hopefully some of that work will make it
into mainline in the near future ;)
