SPI platform devices are defined in respective machine folder of
Samsung S3C64XX and S5P series SoCs.This patchset moves S3C64XX
and S5P series of SPI platform devices to a common place plat-samsung.
This patchset also creates SPI setup files for GPIO configurations and
platform data initialization.
V2 Changes:
Platform data initialized in a centralized setup file as suggested-by
Mark Brown
SPI Controller number is added in SPI controller defining structure.
V3 Changes:
Reverted the SPI Controller number addition because device tree doesn't support
enumeration using device instance number.
Padmavathi Venna (6):
ARM: SAMSUNG: Consolidation of SPI platform devices to plat-samsung
ARM: S3C64XX: Modified files for SPI consolidation work
ARM: S5PC100: Modified files for SPI consolidation work
ARM: S5P64X0: Modified files for SPI consolidation work
ARM: S5PV210: Modified files for SPI consolidation work
ARM: S3C64XX: Modified according to SPI consolidation work.

As SPI platform devices are consolidated to plat-samsung, some
corresponding changes are required in the respective machine folder.
Setup files are added for SPI GPIO configurations and platform data
initialization.

As SPI platform devices are consolidated to plat-samsung, some
corresponding changes are required in the respective machine folder.
Added SPI Setup file for GPIO configurations and platform data
initialization.
