Yes, i got the problem with the patch. I guess it's better to g ahead
with Seungwon's patch.

Hi Subhash,
As Mr. Seungwon mentioned, your patch didn't solve the dead-lock issue.
I'm prefered to the seungwon's patch.

Hi Dan,
Correct. I will prevent this kind of breaking in the future.
However, after our analysis the breaking of patch 1/3 and 2/3 should not
fail old devices. And since Samuel has applied 2/3 and 3/3, it might be
better for Chris to apply patch 1/3 and let all this things appear in
kernel v3

Implement device_slave_sg_caps().
EDMA has a finite set of PaRAM slots available for linking a
multi-segment SG transfer. In order to prevent any one channel
from consuming all PaRAM slots to fulfill a large SG transfer,
the driver reports a static per-channel max number of SG segments
it will han
Add a dmaengine API to retrieve slave SG transfer capabilities.
The API is optionally implemented by dmaengine drivers and when
unimplemented will return a NULL pointer. A client driver using
this API provides the required dma channel, address width, and
burst size of the transfer. dma_get_slave_s
Replace the hardcoded values used to set max_segs/max_seg_size with
a dma_get_slave_sg_caps() query to the dmaengine driver.

Changes since v2:
- Change to a separate slave sg specific api. Drop the
generic per-channel capabilities api that is not used.
Changes since v1:
- Use the existing dma_transaction_type enums instead of
adding the mostly duplicated dmaengine_apis enums

Hi,
I'm working on a SDHCI driver for linux kernel 3.4.
The IP that I have to control does not control the Driver Strength.
Driver Type B is always selected. On the other hand, I can control the
drive strength of the pads in software.
I would like to use the interface select_drive_strength
