The existing driver supports gpio based /cs signal.
For controller's that have one device per controller,
the slave device's /cs signal might be internally controlled
by the chip select bit of slave select register. They are not
externally asserted/deasserted using gpio pin.

This patch adds support for the exynos5440 spi controller.
The integration of the spi IP in exynos5440 is different from
other SoC's. The I/O pins are no more configured via gpio, they
have dedicated pins.

This patch series adds support for the polling mode only. Also 2nd patch
in the series adds support for dedicated cs pin. After Thomas's patch for
using default gpio is merged(commit id: 00ab539), one of the patch in this
series is dropped and new series is generated.

The 64xx spi driver supports partial polling mode.
Only the last chunk of the transfer length is transferred
or recieved in polling mode.
Some SoC's that adopt this controller might not have have dma
interface. This patch adds support for complete polling mode
and gives flexibit
