Pull MFD bits from Samuel Ortiz:
"We have support for a few new drivers:
- Samsung s2mps11
- Wolfson Microelectronics wm5102 and wm5110
- Marvell 88PM800 and 88PM805
- TI twl6041
We also have our regular driver improvements:
- Device tree and IRQ domain support for STE AB8500
- Regmap and devm_* API conversion for TI tps6586x
- Device tree support for Samsung max77686
- devm_* API conversion for STE AB3100
Besides that, quite a lot of fixing and cleanup for mc13xxx, tps65910,
tps65090, da9052 and twl-core."
Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI:
centralize controller initialization") that clashed with commit
2761a6394516 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").
In particular, commit 2761a6394516 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).
I left that part of commit 2761a6394516 just undone.
