[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.
