Currently, spi-s3c64xx.c needs "cs-gpio" chip select GPIO to be
defined under "controller-data" node under each slave node.
&spi_x {
cs-gpios <>;
...
slave_node {
controller-data {
cs-gpio = <>;
...
};
...
};
...
};
Where as, SPI core and many other drivers uses "cs-gpios" for
from device tree node.
Hence, make changes in spi-s3c64xx.c driver to make use of
"cs-gpios" from SPI node(parent) instead of "cs-gpio" defined in
slaves "controller-data"(child) node.
Also, fixes a compilation warning and corrects the DTS nodes for
Exynos4210 based SMDKv310, Exynos4412 based Trats2, Exynos5250 based
SMDK5250 boards.
