Entries in the clocks and clock-names can be in any order, the only
requirement normally is that they match. I would rephrase this to
something along the lines of:
- clocks : should contain the JPEG codec IP gate clock specifier and
for the Exynos3250 SoC additionally the SCLK_JPEG entry; from the
common clock bindings;
