2011-07-21ARM: S3C64XX: Fix WM8915 IRQ polarity on CragganmoreMark Brown
The chip IRQ output is genuinely an IRQ output rather than /IRQ output by default - this had been working due to an interface issue with the IRQ controller. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2011-07-21ARM: S3C64XX: Configure supplies for all Cragganmore regulatorsMark Brown
All the regulators on the system are supplied from the fixed wall supply. While there's no functional value in telling the regulator core this it does ensure that as a regulator maintainer I'll be exercising the supply logic frequently.

2011-07-21ARM: S3C64XX: Refresh Cragganmore supportMark Brown
The original Cragganmore code was submitted while new code was being refused for mainline. This patch was unexpectedly merged upstream but development had continued in the expectation that the code would be resubmitted later so no split patches were maintained. This patch synchronises that work with the recently merged driver. The main changes are fleshing out of the PMIC and audio integration for the system, including addition of the Dallas Dhu and Tobermory audio modules, plus some minor updates to account for revision 2 hardware.

2011-07-21ARM: S3C64XX: Initial support for Wolfson/Simtec Cragganmore/BanffMark Brown
The Cragganmore carrier card and Banff CPU module are used on Wolfson Microelectronics reference systems. This initial support covers the core system which is a fairly generic S3C6410 based design, further patches will add support for the key features of the reference system. The initial board bringup and therefore much of the key code was done by Ben Dooks for Simtec, with additional work (especially around the integration of the Wolfson devices) being done by myself.

2011-07-20ARM: SAMSUNG: Add support for pre-sleep/post-restore gpio controlBen Dooks
Add a callback so that per-arch can do pre-sleep and post-resume gpio configuration so that for the S3C64XX, the GPIO configuration is restored before the sleep mode is cleared. For the S3C64XX case, it means that the GPIOs get set back to normal operation after the restore code puts the original configurations back in after the Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2011-07-20ARM: S3C64XX: Ensure VIC based IRQs can be resumed fromBen Dooks
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.

This is a straight code motion patch, there are no changes to the driver itself. The Kconfig is left untouched as the ARM CPUfreq Kconfig is all in one big block in arm/Kconfig and should be moved en masse rather than being done piecemeal.

2011-07-02ARM: pm: allow suspend finisher to return error codesRussell King
There are SoCs where attempting to enter a low power state is ignored, and the CPU continues executing instructions with all state preserved. It is over-complex at that point to disable the MMU just to call the resume path. Instead, allow the suspend finisher to return error codes to abort suspend in this circumstance, where the cpu_suspend internals will then unwind the saved state on the stack. Also omit the tlb flush as no changes to the page tables will have happened. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-06-24ARM: pm: samsung: move cpu_suspend into C codeRussell King
Move the call to cpu_suspend into C code, and noticing that all the s3c_cpu_save implementations are now identical, we can move this into the common samsung code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-06-24ARM: pm: mach-s3c64xx: cleanup s3c_cpu_saveRussell King

2011-06-24ARM: pm: convert cpu_suspend() to a normal functionRussell King
cpu_suspend() has a weird calling method which makes it only possible to call from assembly code: it returns with a modified stack pointer to finish the suspend, but on resume, it 'returns' via a provided pointer. We can make cpu_suspend() appear to be a normal function merely by swapping the resume pointer argument and the link register. Do so, and update all callers to take account of this more traditional behaviour.
