I did refer to manuals of s3c24xx to Exynos to ensure that the samsung pinctrl driver is generic and reusable on all samsung soc's. I hope I have not missed out something important that would require additional tweaks in the samsung pinctrl driver. The missing bits now are gpio interrupt and wakeup interrupt support in the samsung pinctrl driver. Once that is complete, I believe it should be easy to add support for other SoC and convert the drivers to use pinctrl (other option being to let pinctrl driver hog all the mappings at boot and remove the cfg_gpio platform callbacks from the driver). Thank you Mark for your comments.
