Add a dmaengine API to retrieve slave SG transfer limits.
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.
Replace the hardcoded values used to set max_segs/max_seg_size with
a dma_get_slave_sg_limits() query to the dmaengine driver.

Implement device_slave_sg_limits().
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
Changes since v3:
- Change api name to dma_get_slave_sg_limits() to avoid
confusion with h/w caps which are static.
Changes since v2:
- Change to a separate slave sg specific api. Drop the
generic per-channel capabilities api that is not used.

zswap is a thin compression backend for frontswap. It receives
pages from frontswap and attempts to store them in a compressed

The SSD1307 was used in an early prototype that will never get
distributed. The final board now has a SSD1306 instead, that has its own
power generation unit and thus doesn't need any PWM. The panel attached
to it also changed.

The Solomon SSD1306 OLED controller is very similar to the SSD1307,
except for the fact that the power is given through an external PWM for
the 1307, and while the 1306 can generate its own power without any PWM.

Hi Linus,
Looking at commit 13da9e200fe4740b02cd51e07ab454627e228920, I suspect the
answer will be no, but can we please revisit the use of __BYTE_ORDER in the
kernel?
The reason for this is that I've noticed a number of places in the UAPI
headers where __LITTLE_ENDIAN and __BIG_ENDIAN are

Move mach-davinci/dma.c to common/edma.c so it can be used
by OMAP (specifically AM33xx) as well.
