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 and exynos5250-smdk5250.dts 3. Updates the DT bindings. Note: This patchset is a rework of the changes under review @ http://www.mail-archive.com/devicetree@xxxxxxxxxxxxxxx/msg34501.html 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 http://www.gossamer-threads.com/lists/linux/kernel/1951607 Tested-by on boards based on Exynos4, S5P, S3C series SoCs would be appreciated.
