6e726ea4f5 ARM: EXYNOS: Select SPARSE_IRQ for Exynos
This patch adds selection of CONFIG_SPARSE_IRQ for ARCH_EXYNOS, since it
is required by multiplatform and allows to remove the legacy mach/irqs.h
header.

To make this possible, a dummy IRQ_EINT_BIT macro is added to pm-core.h
header to allow plat-samsung/pm.c compile. This macro is irrelevant for
Exynos and will be removed after reworking Samsung pm code for
multiplatform compatibility.

This patch adds several compatibility definitions that are not relevant
for Exynos, but are required by Samsung PM core.

b134dc3fea ARM: EXYNOS: Fix EINT wake-up mask configuration when pinctrl is used
On DT-enabled systems pinctrl-exynos driver is responsible for handling
of wake-up EINT interrupts. This patch adjusts wake-up mask
configuration code to take wake-up mask value from pinctrl-exynos driver
on DT-enabled systems.

8521420375 ARM: EXYNOS: Clear ENABLE_WAKEUP_SW bit when entering suspend
Setting this bit to 0 causes the system to wait until suspended
to use the wakeup masks.  With it being set high previously,
masked interrupts were being received and processed before the
EINT_WAKEUP_MASK was configured.

672b6829e7 ARM: EXYNOS: Remove hardcode wakeup unmask for EINT_0
For legacy reasons EINT_0 was being forced on for all
exynos systems as a wake interrupt.  For boards that need
EINT_0 they should probably enable it with enable_irq_wake

830145796a ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynos
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.
