2016-03-18ARM: uniphier: rework SMP code to support new System Bus bindingMasahiro Yamada
During the review process of the UniPhier System Bus driver (drivers/bus/uniphier.c), the current binding of the System Bus Controller turned out to be no good. In order to use the driver, some nodes in the device trees must be tweaked. It would also have impacts on the SMP code because the SMP related registers are located in the System Bus Controller block. This commit reworks the smp_operations to support the new binding, but still supports the old binding, too.

i.MX only needs to select ARM_CPU_SUSPEND manually for the very specific case that CONFIG_PM_SLEEP is disabled and imx6 is used with CONFIG_PM enabled for runtime PM. If we are building a kernel only for CPUs that are not using the cpu_suspend() helper, we otherwise get a harmless build warning: warning: (ARCH_MXC && SOC_IMX23 && SOC_IMX28 && ARCH_PXA && MACH_MVEBU_V7 && ARCH_OMAP3 && ARCH_OMAP4 && SOC_OMAP5 && SOC_AM33XX && SOC_DRA7XX && ARCH_EXYNOS3 && ARCH_EXYNOS4 && EXYNOS5420_MCPM && EXYNOS_CPU_SUSPEND && ARCH_VEXPRESS_TC2_PM && ARM_BIG_LITTLE_CPUIDLE && ARM_HIGHBANK_CPUIDLE && QCOM_PM) selects ARM_CPU_SUSPEND which has unmet direct dependencies (ARCH_SUSPEND_POSSIBLE) This moves the option to the SOC_IMX6 option that actually requires it, in effect reverting commit f36b594f3754 ("ARM: mach-imx: Select ARM_CPU_SUSPEND at ARCH_MXC level") that was meant as a cleanup and unintentionally caused this warning.

2016-02-22ARM: OMAP2+: DMA: Provide dma_slave_map to omap-dma for legacy bootPeter Ujfalusi
We still have some boards booting in legacy mode and they will need to have the device/slave -> filter_fn mapping so we can convert the OMAP drivers to use the new dmaengine API for requesting channels. Only some OMAP24xx and OMAP3xxx boards can boot in legacy mode which means we only need to provide the map for these SoCs.

2016-02-22ARM: OMAP1: DMA: Provide dma_slave_map to omap-dmaPeter Ujfalusi
OMAP1 can not boot in DT mode and to be able to clean up the driver regarding to the dmaengine API use (switching to the new API) the device/slave -> filter mapping needs to be provided to the omap-dma driver.
