Laxman Dewangan 766ed70447 spi: remove check for bits_per_word on transfer from low level driver
The spi core make sure that each transfer structure have the proper
setting for bits_per_word before calling low level transfer APIs.

Hence it is no more require to check again in low level driver for
this field whether this is set correct or not. Removing such code
from low level driver.

The txx9 change also removes a test for bits_per_word set to 0, and
forcing it to 8 in that case. This can also be removed now since
spi_setup() ensures spi->bits_per_word is not zero.

	if (!spi->bits_per_word)
		spi->bits_per_word = 8;

Grant Likely fd4a319bc9 spi: Remove HOTPLUG section attributes
CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Bill Pemberton has done most of the legwork on this series. I've used
his script to purge the attributes from the drivers/gpio tree.

Alexander Shiyan 161b96c383 spi/clps711x: New SPI master driver
This patch add new driver for CLPS711X SPI master controller.
Due to platform limitations driver supports only 8 bit transfer mode.
Chip select control is handled via GPIO.
