The divider values stored in the per chip data are only used to set the

are calculated per transfer based on the t->speed_hz there is no reason
keep them in the per chip data.

and return the dividers thru pointers. Remove the divider values from

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;

spi/spi-ep93xx.c: use dma_transfer_direction instead of dma_data_direction

A new enum indicating the dma channel direction was introduced by:

commit 49920bc66984a512f4bcc7735a61642cd0e4d6f2
dmaengine: add new enum dma_transfer_direction

The following commit changed spi-ep93xx to use the new enum:

commit a485df4b4404379786c4bdd258bc528b2617449d
spi, serial: move to dma_transfer_direction

In doing so a sparse warning was introduced:

warning: mixing different enum types
int enum dma_data_direction versus
int enum dma_transfer_direction

This is produced because the 'dir' passed in ep93xx_spi_dma_prepare
is an enum dma_data_direction and is being used to set the
dma_slave_config 'direction' which is now an enum dma_transfer_direction.

Fix this by converting spi-ep93xx to use the new enum type in all
places.
