I think that the approach with timing_base, as suggested by Joonyoung Shim,
would be much cleaner.
Leela: Okay, will go with timing_base approach only

If I see correctly, this will crash on a null pointer dereference on
Exynos4 without DT, because of NULL driver_data.
Leela: yes, you are right, will take care of this
P.S. I think you should CC linux-arm-kernel and linux-samsung-soc lists
when submitting patches related to ARM and Samsung SoCs.
Leela: Okay, will do it next time.
Best regards,
