2012-12-14ARM: arm-soc: Merge branch 'next/smp' into next/soc2Olof Johansson
Merging in the smp-on-socfpga branch into soc2 since the topics are similar and it's a short branch in the first place. * next/smp: ARM: socfpga: mark secondary_trampoline as cpuinit socfpga: map uart into virtual address space so that early_printk() works ARM: socfpga: fix build break for allyesconfig ARM: socfpga: Enable SMP for socfpga Signed-off-by: Olof Johansson <olof@lixom.net>

2012-11-20ARM: EXYNOS: Add ARM down clock supportAbhilash Kesavan
In idle state down clocking the arm cores can result in power savings. Program the power control registers to achieve this and save these registers across a suspend/resume cycle. Signed-off-by: Abhilash Kesavan <a.kesavan@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2012-11-20ARM: EXYNOS: Fix i2c suspend/resume for legacy controllerAbhilash Kesavan
On resuming from suspend the i2c configuration register that is part of system controller resets to 0xf. This sets the interrupt source to the new high speed i2c rather than the legacy one that we are using. Save and restore the I2C_CFG register for exynos5 to fix this.

2012-11-20ARM: EXYNOS: Setup legacy i2c controller interruptsAbhilash Kesavan
On Exynos5 we have a new high-speed i2c controller. The interrupt sources for the legacy and new controller are muxed and are controlled via the SYSCON I2C_CFG register. At reset the interrupt source is configured for the high-speed controller, to continue using the old i2c controller we need to modify the I2C_CFG register.
