0914498171 dt-bindings: spmi: add support for glymur-spmi-pmic-arb (arbiter v8) 
SPMI PMIC Arbiter version 8 builds upon version 7 with support for
up to four SPMI buses.  To achieve this, the register map was
slightly rearranged.  Add a new binding file and compatible string
for version 8 using the name 'glymur' as the Qualcomm Technologies,
Inc. Glymur SoC is the first one to use PMIC arbiter version 8.  This
specifies the new register ranges needed only for version 8.

Also document SPMI PMIC Arbiter for Qualcomm Kaanapali SoC, by adding
fallback to Glymur compatible string, as it too has version 8
functionality.

e9ae440c97 dt-bindings: spmi: split out common QCOM SPMI PMIC arbiter properties 
Split out the common SPMI PMIC arbiter properties for QCOM devices into a
separate file so that it can be included as a reference for devices
using them. This will be needed for the upcoming PMIC v8 arbiter
support patch, as the v8 arbiter also uses these common properties.

006d350609 dt-bindings: spmi: apple,spmi: Add t6020-spmi compatible 
After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,spmi" anymore [1]. Use
"apple,t8103-spmi" as base compatible as it is the SoC the driver and
bindings were written for.

The SPMI controller on Apple M2 Pro/Max/Ultra is compatible to
"apple,t8103-spmi" so add its per-SoC compatible with the former as
fallback used by the existing driver.

Add dedicated schema for X1E80100 PMIC ARB. This is not the first
platform to introduce multiple buses. In fact, all platforms that
implement the version 7 for the SPMI PMIC arbiter have multiple buses.
Since the compatible should not be version based, the platform specific
one is used. The X1E80100 platform is the first platform to really need
the second master, as all the available boards have the PMICs that
provide the eUSB2 repeater on the second bus.
