Merge tag 'drivers-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver changes from Olof Johansson:
"A handful of driver-related changes. We've had a bunch of them going
in through other branches as well, so it's only a part of what we
really have this release.
Larger pieces are:
- Removal of a now unused PWM driver for atmel
[ This includes AVR32 changes that have been appropriately acked ]
- Performance counter support for the arm CCN interconnect
- OMAP mailbox driver cleanups and consolidation
- PCI and SATA PHY drivers for SPEAr 13xx platforms
- Redefinition (with backwards compatibility!) of PCI DT bindings for
Tegra to better model regulators/power"
Note: this merge also fixes up the semantic conflict with the new
calling convention for devm_phy_create(), see commit f0ed817638b5 ("phy:
core: Let node ptr of PHY point to PHY and not of PHY provider") that
came in through Greg's USB tree.
Semantic merge patch by Stephen Rothwell <sfr@canb.auug.org.au> through
the next tree.
