Instead of, wrongly, reusing the 'val' variable, use a dedicated

Since the driver is meant to manage SPI of newer SoCs as well, we
need to define a new structure member for latest SoC that has the
SPI clock control/scaling block moved from the controller to the
platform's clock management unit.
The flag should be set to 'true' by any SoC that has SPI controller
Newer SoCs have the SPI clock scaling control in platform's
clock management unit. Inorder for such SoCs to work, we need
to check the flag clk_from_cmu before making any clock changes.

Hi,
Here come six bug fixes and enhancements to the S3C64XX
spi controller driver.
The first 4 are bug/warning fixes, the last two are to
enable the spi_s3c64xx.c to manage SPI controllers of newer
Samsung SoCs with essentially the same IP but scalar logic
moved into core clock management unit.

This patch changes the way SPI transfers are setup. The previous
method uses the pl022_config_chip data for configuration of
loopback mode, edge count, clock polarity, number of data bits,

Some explanations:
This patchset is to add SPI support in the existing spi_imx driver for
i.MX51 and add SPI relating stuffs for mx51_3ds board level.
i.MX51 has two eCSPI controllers and one CSPI controller, CSPI
controller is 100% compatible with the one of i.MX35, so we don't need
to add new f
There are 3 SPI controllers on i.MX51, one is called CSPI and is
100% compatible with the one on i.MX35, the other two are called
eCSPI and are not compatible with existing controllers on other
i.MX platforms, here we add support of these three controllers in
the imx spi driver.
