Doing
/include/ "omap44xx-clocks.dtsi" might avoid including that header in
corresponding SoC dtsi,
OR:

Since we already have omap443x.dtsi and omap446x.dtsi, do we need
clock.dtsi containing just a few entries?
instead we could define the delta clocks in the clocks section, and save
on two additional files, no?

is there a naming convention used here? abe_clk, fclk etc?
