2011-07-20ARM: SAMSUNG: ADC Channel selectionMyungJoo Ham2-10/+20
In S5PV210/S5PC110/EXYNOS4, ADCMUX channel selection uses ADCMUX register, not ADCCON register. This patch corrects the behavior of SAMSUNG-ADC for such CPUs.

2011-07-20ARM: SAMSUNG: use regulator VDD for ADCMyungJoo Ham1-4/+27
This patch allows the Samsung ADC driver to enable VDD regulator at probe and resume and to disable at exit and suspend. In a platform where ADC's VDD regulator is not "always-on", this control is required although this patch does not provide fine-grained power control (turning on the regulator only when being accessed). However, if VDD regulator ("vdd" for the adc device) is not provided, the regulator control will not be activated because there are platforms that do not provide regulator for ADC device. arch_initcall has been modified to module_init in order to allow regulators to be available at probe.

We need to balance between set and check S5P_CENTRAL_SEQ_CONFIGURATION register in syscore_ops suspend/resume function when failure in enter suspend mode.

2011-07-20ARM: EXYNOS4: Support early wakeup entering sleep modeJaecheol Lee1-21/+19
Since early wakeup can be handled in pm so we don't need masking interrupts of external GIC. When the early wakeup interrupt happens, PMU(Power Management Unit) ignores WFI instruction. This means that PC(Program Counter) passed without any changes. This patch can handle that case by early wakeup interrupt.

EXYNOS4 supports 3 different system level power down mode by PMU (Power Management Unit). Each power down mode need to configure many PMU registers with different value. This patch supports function to configure PMU registers with pre-defined values in PMU code. This function may be used by PM code and AFTR/LPA support driver.

2011-07-20ARM: EXYNOS4: Remove clock event timers using ARM private timersChanghwan Youn7-343/+4
External GIC cannot support PPI (Private Peripheral Interrupt) for ARM private timers. Thus MCT should be selected as clock event timers by default. Signed-off-by: Changhwan Youn <chaos.youn@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2011-07-20ARM: EXYNOS4: Add support external GICChanghwan Youn4-1/+42
For full support of power modes, this patch adds implementation external GIC on EXYNOS4. External GIC of Exynos4 cannot support register banking so several interrupt related code for CPU1 should be different from that of CPU0.

2011-07-20ARM: GIC: move gic_chip_data structure declaration to headerChanghwan Youn2-6/+6
Since Samsung EXYNOS4210 cannot support register banking in GIC, so needs to update CPU interface base address. The 'gic_chip_data' is used for it, this patch moves gic_chip_data structure declaraton to arch/arm/include/asm/hardware/gic.h to use it.

2011-07-20ARM: EXYNOS4: set the affinity of mct1 interrupt using IRQ_MCT_L1Changhwan Youn1-1/+1
IRQ_MCT_L1 is connected directly to GIC in external GIC mapping, while in internal GIC mapping, it is connected to GIC through interrupt combiner. Therfore the affinity for mct1 event timer interrupt should be changed through IRQ_MCT_L1. Signed-off-by: Changhwan Youn <chaos.youn@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2011-07-20ARM: S3C64XX: Ensure VIC based IRQs can be resumed fromBen Dooks2-3/+11
Any interrupts based off either of the onboard VICs cannot be resumed from any more as it seems set_irq_wake() is now checking the error code returned from the low level handlers and not setting the wake-state on the interrupt if this fails. Ensure that we make the interrupts we can resume from available on the VIC and then do a pre-sleep mask of all the VIC interrupts as the wakeup is handled by a seperate block.
