This will allow to use gpio for chip select with no modification in the
driver binding
When use the cs-gpios, the gpio number will be passed via the cs_gpio field
and the number of chip select will automatically increased.

The status of transfer is stored in controller data structure
so that it can be used not only by atmel_spi_msg_done() function.
This will be useful for upcoming dmaengine enabled driver.

Hi Lars,
The logic of setting SPI_XCOMM_SETTINGS_CPHA bit looks wrong to me.
Can you check if this patch works?
Thanks,

This driver is obsolete and can't even be built anymore since the
platform it depends has been removed.
The STMP series is completely covered by the MXS platform these days, so
spi-mxs can be used instead.

Without this patch, a SPI device may keep its drvdata whereas it was unbound
from its driver. This may result in accessing an invalid pointer.
As for i2c-core, let the SPI core handle the removal of the device's drvdata,
after a remove(), or a probe() failure.
This is a resent of the previous pat
This adds OF support to DaVinci SPI controller to configure platform
data through device bindings. Also replaces clk_enable() with
of clk_prepare_enable() as well as clk_disable() with
clk_disable_unprepare().

This adds OF support for DaVinci SPI driver. Following are changes from initial
version based on mostly review comments.
- removed attribute for spi version. instead, compatibility string is
modified to include version info.
- pdata ptr in davinci_spi_platform_data is replaced with struct itse
