New feature development This adds support for new features, and contains stuff from most platforms. A number of these patches could have fit into other branches, too, but were small enough not to cause too much confusion here. * tag 'devel' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (28 commits) mfd/db8500-prcmu: remove support for early silicon revisions ARM: ux500: fix the smp_twd clock calculation ARM: ux500: remove support for early silicon revisions ARM: ux500: update register files ARM: ux500: register DB5500 PMU dynamically ARM: ux500: update ASIC detection for U5500 ARM: ux500: support DB8520 ARM: picoxcell: implement watchdog restart ARM: OMAP3+: hwmod data: Add the default clockactivity for I2C ARM: OMAP3: hwmod data: disable multiblock reads on MMC1/2 on OMAP34xx/35xx <= ES2.1 ARM: OMAP: USB: EHCI and OHCI hwmod structures for OMAP4 ARM: OMAP: USB: EHCI and OHCI hwmod structures for OMAP3 ARM: OMAP: hwmod data: Add support for AM35xx UART4/ttyO3 ARM: Orion: Remove address map info from all platform data structures ARM: Orion: Get address map from plat-orion instead of via platform_data ARM: Orion: mbus_dram_info consolidation ARM: Orion: Consolidate the address map setup ARM: Kirkwood: Add configuration for MPP12 as GPIO ARM: Kirkwood: Recognize A1 revision of 6282 chip ARM: ux500: update the MOP500 GPIO assignments ...
