2016-06-29soc: renesas: rcar-sysc: Move SYSC interrupt config to rcar-sysc driverGeert Uytterhoeven4-15/+11
On R-Car H1 and Gen2, the SYSC interrupt registers are always configured using hardcoded values in platform code. For R-Car Gen2, values are provided for H2 and M2-W only, other SoCs are not yet supported, and never will be. Move this configuration from SoC-specific platform code to the rcar_sysc_init() wrapper, so it can be skipped if the SYSC is configured from DT. This would be the case not only for H1, H2, and M2-W using a modern DTS, but also for other R-Car Gen2 SoCs not supported by the platform code, relying purely on DT. There is no longer a need to return the mapped register block, hence make the function return void.

2016-06-22ARM: OMAP4+: Reset CPU1 properly for kexecTony Lindgren1-26/+70
We need to reset CPU1 properly for kexec when booting different kernel versions. Otherwise CPU1 will attempt to boot the the previous kernel's start_secondary(). Note that the restctrl register is different from the low-power mode wakeup register CPU1_WAKEUP_NS_PA_ADDR. We need to configure both. Let's fix the issue by defining SoC specific data to initialize things in a more generic way. And let's also standardize omap-smp.c to use soc_is instead of cpu_is while at it.

2016-06-22ARM: OMAP4+: Prevent CPU1 related hang with kexecTony Lindgren4-8/+32
Kexec booted kernels on omap4 will hang early during the boot if the booted kernel is different version from the previous kernel. This is because the previous kernel may have configured low-power mode using CPU1_WAKEUP_NS_PA_ADDR. In that case it points to the previous kernel's omap4_secondary_startup(), and CPU1 can be in low power mode from the previous kernel. When the new kernel configures the CPU1 clockdomain, CPU1 can wake from low power state prematurely during omap44xx_clockdomains_init() running random code. Let's fix the issue by configuring CPU1_WAKEUP_NS_PA_ADDR before we call omap44xx_clockdomains_init(). Note that this is very early during the init, and we will do proper CPU1 reset during SMP init a bit later on in omap4_smp_prepare_cpus(). And we need to do this when SMP is not enabled as the previous kernel may have had it enabled.

Prepare things for making kexec work on SMP omap variants by initializing SARM RAM base early. This allows us to configure CPU1 for kexec in case the previous kernel has put CPU1 in low power mode. Note that this should not prevent moving other SAR RAM code to live under drivers. However for kexec, we will need this very early.

2016-06-22ARM: EXYNOS: Fix UART address selection for DEBUG_LLJoonyoung Shim1-1/+5
The Exynos542x SoCs using A15+A7 can boot to A15 or A7. If it boots using A7 (like on Odroid XU family boards), it can't choose right UART physical address only the part number of CP15. Fix the detection logic by checking the Cluster ID additionally.

2016-06-21ARM: keystone: fix missing keystone.h in pm_domain.cBen Dooks1-0/+2
The declaration of keystone_pm_runtime_init() is not included from keystone.h in pm_domain.c. Including the file fixes the following sparse warning: arch/arm/mach-keystone/pm_domain.c:37:12: warning: symbol 'keystone_pm_runtime_init' was not declared. Should it be static?
