The S3C64xx SoCs contain a set of gateable power domains which can be enabled and disabled at runtime in order to save power. Use the generic power domain code to implement support for these in software, enabling runtime control of most domains: - ETM (not supported in mainline). - Domain G: 3D acceleration (no mainline support). - Domain V: MFC (no mainline support). - Domain I: JPEG and camera interface (no mainline support). - Domain P: 2D acceleration, TV encoder and scaler (no mainline support) - Domain S: Security (no mainline support). - Domain F: LCD (driver already uses runtime PM), post processing and rotation (no mainline support). The IROM domain is marked as always enabled as we should arrange for it to be enabled when we suspend which will need a bit more work. Due to all the conditional device registration that the platform does wrap s3c_pm_init() with s3c64xx_pm_init() which actually puts the device into the power domain after the machines have registered, looking for platform data to tell if the device was registered. Since currently only Cragganmore actually sets up PM that is the only machine updated.

The S3C64xx CPUs have power gating support with a series of software controllable power domains in the SoC. To take full advantage of these we should implement runtime PM support but since several of the IP blocks have no in tree drivers (and at this point aren't likely to acquire such drivers) we can get some benefit from the hardware much more easily if we just turn those blocks off unconditionally. This will cut down on the leakage these domains generate without interfering with active usage. Do this for: - Domain G: 3D acceleration - Domain V: MFC - Domain I: JPEG and camera interface - Domain P: 2D acceleration, TV encoder and scaler This is easy to reverse if any of these devices do acquire drivers in the future or as part of out of tree patches for them.

This patch makes sure that the LCD bypass state is preserved during sleep mode. It achieves this by saving the S3C64XX_MODEM_MIFPCON register, which is not handled by any other code currently. Signed-off-by: NTomasz Figa <tomasz.figa@gmail.com> Signed-off-by: NKukjin Kim <kgene.kim@samsung.com>

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: NRussell King <rmk+kernel@arm.linux.org.uk>

Move the GPIO suspend/resume support inline with the gpiolib support so that it will work with both the S3C24XX and S3C64XX series. The s3c_gpio_chip is extended to have a pm callback and a save block to keep the state of the GPIO over suspend, and the code from the s3c24xx implementation is added to a new common file. The suspend process now uses the list of registered chips to go through saving and restoring each one as appropriate, using the pm callback to select the appropriate routine depending on the type of control register present. This change also means that any additional GPIO added should not require changes to the PM. Signed-off-by: NBen Dooks <ben-linux@fluff.org>
