At least we can understand easily what is being changed.  Readability, 
particularly by others not familiar with the clock data, is more important 
to me.

So like Saravana, I too prefer C99 structure initializers.  At least there 
should be a choice.

Quick quiz: in this line below:

imx_clk_divider("foo_clk", "bar_clk", CCM_BASE + 0x20, 0x5, 0x3);

which field is the bitfield shift and which is the bitfield width? :-)
