[PATCH 2/2] gpio/exynos: Add support for Exynos4x12 SoC
Joonyoung Shim
jy0922.shim at samsung.com
Thu May 17 22:18:17 EDT 2012
Exynos4x12 GPIO part1 and part2 layouts are different with that of
Exynos4210. So, it needs to support gpios for Exynos4x12 SoC. This
doesn't support GPVx Exynos4x12 GPIO part4 yet.
In the Exynos4x12 GPIO part1 and part2, the interval of base register
offset is 0x20 but GPF0, GPJ0, GPK0 and GPM0 ignore the 0x20 interval
and have new value. The interrupt reg offset also is about GPF0 and GPK0
too. Refer the below layout.
