Change the code that does the following: if (s3c_cpu_save(regs_save) == 0) { flush_cache_all(); S3C_PMDBG("preparing to sleep\n"); pm_cpu_sleep(); } to simply call s3c_cpu_save, and let that do the necessary calls to quiesce and sleep the system.

This triggers a warning due to the call of a function that might sleep whilst the system is not in a valid state to do so. Move the allocation and free to points in the suspend and resume process where they can call a function that might-sleep. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

This means moving the GPIO bank numbers to a separate file to allow the gpio and regs-gpio to include them. Including regs-gpio.h into gpio.h causes too many build problems and adding gpio.h would mean editing a large number of files. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

This will also allow us to save the UDIVSLOT register on newer SoCs. Move to using a structure for the UART use the extant Kconfig configuration specifying the number of UARTs.

In OMAP sDMA, contrast to the SDMA.DMA4_CSRi registers, the SDMA.DMA4_IRQSTATUS_Lj registers are updated regardless of the corresponding bits in the SDMA.DMA4_IRQENABLE_Lj registers. Since there are four sDMA interrupt lines and if more than one line is actively used by two concurrently running sDMA softwares modules,then the spurious interrupt can be observed on the other lines. Fix in this patch will only dispatch the relevant and enabled interrupts on a particular line thus perevting spurious IRQ.

It is needed since the OMAP DMA is a system wide resource and can be used by another software apart from the kernel.

The default bus speed is typically set to speed of slowest I2C chip on the bus and overriding allow to use some experimental configurations or updated chip versions without any kernel modifications.
