pch_dma: Fix DMA setting issue

2011-05-09T11:42:23+00:00

Currently, Direct-Start mode(*) is enabled.
Our IOH's devices must not use this mode.
This causes unexpected behavior.
This patch deletes Direct-Start setting.
(*) This mode is used in order for CPU to generate the DMA request.

pch_dma: fix dma direction issue for ML7213 IOH video-in

2011-05-09T11:42:23+00:00

Currently, even-channel number is set as tx direction and odd is set as rx.
However, though video-in uses ch6, the direction is not tx but rx.
This patch sets video-in's DMA direction correctly.

drivers, pch_dma: Fix warning when CONFIG_PM=n.

2011-03-06T19:56:50+00:00

When CONFIG_PM=n, we get the following warning:

drivers/dma/pch_dma.c:741: warning: ‘pch_dma_suspend’ defined but not used
drivers/dma/pch_dma.c:755: warning: ‘pch_dma_resume’ defined but not used

To fix it, wrap pch_dma_{suspend,resume} and
pch_dma_{save,restore}_regs functions with CONFIG_PM.
