[ARM] 3753/1: S3C24XX: DMA fixes
Patch from Ben Dooks A number of small issues with the S3C24XX DMA have cropped up, which this patch fixes. These are: - check wether we can load another buff in start - update state handling in s3c2410_dma_lastxfer - only reload in irq if channel is not idle - more informative timeout errors (add source) - do not call request_irq() with irqs locked - added waitforstop function The patch also adds a S3C2410_DMAOP_STARTED for the occasions when the driver wants to ensure that the DMA system load state is resynced after loading.
