2014-10-28ARM: ux500: Enable Kconfig for the generic PM domainUlf Hansson
Since ux500 uses the generic PM domain, let's enable the corresponding Kconfig as long as CONFIG_PM also is enabled. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2014-10-28ARM: ux500: Initial support for PM domainsUlf Hansson
The ux500 SoC uses the generic PM domain and requires the domains to be specified through DT. Currently the genpd callbacks for handling power gating|ungating are implemented as dummy functions. To be able to enable those to perform PM domain gating/ungating, each device that resides in the VAPE domain must be properly handled from a runtime PM perspective.

2014-10-28ARM: sun4i: a1000: Relicense the device tree under GPLv2/X11Maxime Ripard
The current GPL only licensing on the DTSI makes it very impractical for other software components licensed under another license. In order to make it easier for them to reuse our device trees, relicense our device trees under a GPL/X11 dual-license.

2014-10-28ARM: shmobile: Select CONFIG_ZONE_DMA when CONFIG_ARM_LPAE is enabledLaurent Pinchart
Most IP cores on ARM Renesas platforms can only address 32 bits of physical memory for DMA. Without CONFIG_ZONE_DMA enabled and with the recent CMA highmem allocation support, the default CMA zone is reserved above the 4GiB limit when LPAE is enabled, resulting in various driver failures. Fix the problem by selecting CONFIG_ZONE_DMA. Other options to investigate in the future would be to either enable IOMMU support or use custom CMA reservations for peripherals not supporting LPAE. While not a strict dependency, the "[PATCH 0/4] Low/high memory CMA reservation fixes" series is also required to fix a different but related CMA allocation problem.

Add support for the D4 power domain. This domain contains the Coresight-ETM hardware block. As long as the ARM debug/perf code doesn't use resource management with runtime PM support, the D4 power domain must be kept powered to avoid a crash during resume from s2ram (dbg_cpu_pm_notify() calls reset_ctrl_regs() unconditionally, causing an undefined instruction oops).
