Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Cleanups on various subarchitectures Cleanup patches for various ARM platforms and some of their associated drivers, the bulk of these is for mach-91. Arnd ended up pulling in the restart branch from Russell in order to fix up some simple but annoying merge conflicts. * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (44 commits) arm/at91: fix build of stamp9g20 ARM: u300: delete memory.h MAINTAINERS: add maintainer entry for Picochip picoxcell ARM: picoxcell: move io mappings to common.c ARM: picoxcell: don't reserve irq_descs ARM: picoxcell: remove mach/memory.h ARM: at91: delete the pcontrol_g20_defconfig arm/tegra: Remove code that's ifndef CONFIG_ARM_GIC arm/tegra: remove unused defines arm/tegra: fix variable formatting in makefile ARM: davinci: vpif: move code to driver core header from platform ARM: at91/gpio: fix display of number of irq setuped ARM: at91/gpio: drop PIN_BASE ARM: at91/udc: use gpio_is_valid to check the gpio ARM: at91/ohci: use gpio_is_valid to check the gpio ARM: at91/nand: use gpio_is_valid to check the gpio ARM: at91/mmc: use gpio_is_valid to check the gpio ARM: at91/ide: use gpio_is_valid to check the gpio ARM: at91/pata: use gpio_is_valid to check the gpio ARM: at91/soc: use gpio_is_valid to check the gpio ...
