Merge branch 'prima2/multiplatform' into next/multiplatform
This series enables multiplatform support on the SIRF prima2/marco/atlas6 platform. The code was already quite tidy, so this is a relatively simple change, and it follows similar changes we made to other ARMv7 based platforms recently. * prima2/multiplatform: ARM: sirf: enable support in multi_v7_defconfig ARM: sirf: enable multiplatform support ARM: sirf: use clocksource_of infrastructure ARM: sirf: move debug-macro.S to include/debug/sirf.S ARM: sirf: enable sparse IRQ ARM: sirf: move irq driver to drivers/irqchip ARM: sirf: fix prima2 interrupt lookup pinctrl: sirf: convert to linear irq domain clocksource: make CLOCKSOURCE_OF_DECLARE type safe ARM/dts: prima2: add .dtsi for atlas6 and .dts for atla6-evb board arm: prima2: add new SiRFatlas6 machine in common board ARM: smp_twd: convert to use CLKSRC_OF init clocksource: tegra20: use the device_node pointer passed to init clocksource: pass DT node pointer to init functions clocksource: add empty version of clocksource_of_init Conflicts: arch/arm/configs/multi_v7_defconfig arch/arm/mach-spear/spear13xx.c Tested-by: Barry Song <Barry.Song@csr.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
