Current SPI core has generic implementation for configuring
the Chip select gpios during .setup() & .cleanup(). By modifying
the spi-s3c64xx.c driver to expect the "cs-gpios" property in SPI
device node instead of the subnode "controller-data".
This way we can avoid parsing the "cs-gpios" in the driver.
This patch set also does the following
1. Validate the "struct s3c64xx_spi_csinfo *cs" object and the
CS gpio for both DT and NON-DT before using them.
2. Correct the dt-bindings for exynos4210-smdkv310.dts, exynos4412-trats2.dts
3. Updates the DT bindings.
This patchset is a rework of the changes under review @
Tested on Exynos5420 and Exynos5250 based Peach PIT, PI and Snow boards
respectively using the flashrom utility to access SPI flash.
This patchset is needed by the changes
Tested-by on boards based on Exynos4, S5P, S3C series SoCs
would be appreciated.
