Thank you for reporting.
I didn't check linux-samsung-soc.

The exynos5410, 5420 and 5422 use system register with base address
0x10050000.
But exynos5260 and 5430 are different.
And I can't check exynos5250.

So with this condition, it is reasonable to remove these sysreg relevant
patches.

Thank you.
Best regards YJ
