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. * tag 'drivers-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (38 commits) bus: arm-ccn: Fix error handling at event allocation mailbox/omap: add a parent structure for every IP instance mailbox/omap: remove the private mailbox structure mailbox/omap: consolidate OMAP mailbox driver mailbox/omap: simplify the fifo assignment by using macros mailbox/omap: remove omap_mbox_type_t from mailbox ops mailbox/omap: remove OMAP1 mailbox driver mailbox/omap: use devm_* interfaces bus: ARM CCN: add PERF_EVENTS dependency bus: ARM CCN PMU driver PCI: spear: Remove spear13xx_pcie_remove() PCI: spear: Fix Section mismatch compilation warning for probe() ARM: tegra: Remove legacy PCIe power supply properties PCI: tegra: Remove deprecated power supply properties PCI: tegra: Implement accurate power supply scheme ARM: SPEAr13xx: Update defconfigs ARM: SPEAr13xx: Add pcie and miphy DT nodes ARM: SPEAr13xx: Add bindings and dt node for misc block ARM: SPEAr13xx: Fix static mapping table phy: Add drivers for PCIe and SATA phy on SPEAr13xx ...
