Required properties:
- compatible : should be one of:
"samsung,s5pv210-jpeg", "samsung,exynos4210-jpeg";
"samsung,s5pv210-jpeg", "samsung,exynos4210-jpeg",
"samsung,exynos3250-jpeg";
- reg : address and length of the JPEG codec IP register set;
- interrupts : specifies the JPEG codec IP interrupt;

- clock-names : should contain:
- "jpeg" for the core gate clock,
- "sclk" for the special clock (optional).
- clocks : should contain the clock specifier and clock ID list
matching entries in the clock-names property; from
the common clock bindings.
