We need more registers to be saved and restored for PM of EXYNOS4210. Otherwise, with additional drivers running, suspend-to-RAM fails to wake up properly. This patch adds registers omitted in the initial PM patches. Signed-off-by:

In S5PV210/S5PC110/EXYNOS4, ADCMUX channel selection uses ADCMUX register, not ADCCON register. This patch corrects the behavior of SAMSUNG-ADC for such CPUs. Signed-off-by:

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.

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Cc: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by:

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. Signed-off-by:

That file harkens back to the days of the big 2.4 -> 2.6 version jump, and was based even then on older versions. Some of it is just obsolete, and Jesper Juhl points out that it talks about kernel versions 2.6 and should be updated to 3.0. Remove some obsolete text, and re-phrase some other to not be 2.6-specific. Reported-by:
