Make spi core calculate the message length while
populating the other transfer parameters. This will
be useful in cases where controller driver need to configure its
framelength field without iterating through the linklist again in the
driver controller.

Add support for calculating message length in spi framework.
Add support for quad spi controller.
Patch 2 of this series had been posted before. Sending along
with the series along with ather propsed change.
Sourav Poddar (3):
driver: spi: Modify core to compute the message length
drivers:
The patch add basic support for the quad spi controller.
QSPI is a kind of spi module that allows single,
dual and quad read access to external spi devices. The module
has a memory mapped interface which provide direct interface
for accessing data form external spi devices.
The patch will
Since, qspi controller uses quad read.
Configuring the command register, if the transfer of data needs
quad lines.
This patch has been done on top of the following patch[1], which is still
under review/comments.
This patch will also go changes, as the parent patch[1] does.

The SPI core provides infrastructure for standard message queueing. Use
that instead of handling it in the driver.

Instead of carrying the in-flight message in the driver private
data, use the cur_msg pointer that is already setup by the core.

generic comment, given our historical mistakes of making drivers
specific to a SoC family, it never is.
Now, ti-qspi in file name is a step in the right direction, but, rest
of the code(function names etc) is just married to DRA7 family of
processor
