Current simple-card-utils sets asoc_simple_dai::clk via
asoc_simple_card_parse_clk(), and requested parameter is only
simple_dai. But current simple card drivers are using
simple_dai::clk directly for clk_enable/disable.
Encapsulation is one of simple card util's purpose.

The USB3.0 peripheral controller on R-Car SoCs has a dedicated DMAC.
The DMAC needs a "PRD table" in system memory and the DMAC can have
four PRD tables. This patch adds support for the DMAC.

If you have enabled it all the time, then there won't be a difference
from now. Or?
That also shows how rarely I2C DMA transfers are triggered from within
the kernel :)

No, it will complain loudly with more details about the same things (and

We not only check if the buffer is DMA capable. We also require a
threshold value to see if it makes sense to setup DMA. Since most
I2C transactions are small, the cost for DMA might be too high.

Handling this is special for this driver. Because the hardware needs to

So, after revisiting old mail threads and taking part in a similar discussion
on the USB list, here is an RFC on what I cooked together regarding DMA and I2C

I documented my reasoning with patch 2 which mentions a helper function which
gets added with patch
This ensures also that we fall back to PIO if the buffer is not DMA
capable.
