[PATCH 0/6] intel_mid_dma updates

[Koul, Vinod]

Hi Dan,

Please find attached 6 patches for intel_mid_dma driver, below gives brief 
summary of each patch

1/6: This adds runtime PM support in dma driver, this also adds the driver PCI 
suspend and resume

2/6 & 3/6: These two patches are from Yong Wang: These enable the irq to be 
Shared which is required on some platforms.

4/6: This adds sg list support in dma driver. This is enabled for only two of 4 
devices it supports due to hw support (rest of the two controller don't support 
this in hardware)
In order to support a circular link list approach which we use in our devices, 
we have added a flag DMA_PREP_CIRCULAR_LIST in dma driver header file.
If you agree to this we can move it to dmaengine header file, currently this 
patch adds this in driver header. I will send a new patch for that.

5/6: This is in WARN_ON fix you had request last time

6/6: Last patch moves the new driver to dma_slave_config structure, as agreed 
upon when you accepted last patchset

Thanks
