Pull DeviceTree updates from Rob Herring:
"There's a few orphans in the conversion to %pOF printf specifiers
included here that no one else picked up.
Summary:
- Convert more DT code to use of_property_read_* API.
- Improve DT overlay support when adding multiple overlays
- Convert printk's to %pOF format specifiers. Most went via subsystem
trees, but picked up the remaining orphans
- Correct unittests to use preferred "okay" for "status" property
value
- Add a KASLR seed property
- Vendor prefixes for Mellanox, Theobroma System, Adaptrum, Moxa
- Fix modalias buffer handling
- Clean-up of include paths for building dtbs
- Add bindings for amc6821, isl1208, tsl2x7x, srf02, and srf10
devices
- Add nvmem bindings for MediaTek MT7623 and MT7622 SoC
- Add compatible string for Allwinner H5 Mali-450 GPU
- Fix links to old OpenFirmware docs with new mirror on
devicetree.org
- Remove status property from binding doc examples"

be in examples.

The mvs1 and mvs2 switches are actually called 5vs1 and 5vs2 on
some datasheets. Let's rename them to match the datasheets and
also match the RPM based regulator driver which calls these by
their 5vs names (see qcom_smd-regulator.c). There aren't any
users of these regulators so far, so there aren't any concerns of
DT ABI breakage here. While we're here making updates to the
switches, also mandate usage of the OCP irq for these switches
too.
