I really do not know, but driver char/hw_random/omap-rng.c
support only omap2 and omap4 platforms. So "omap_rng" dev id for
omap3 is not used.
In email [1] you suggested to use clk_get instead clk_get_sys. If
I understand correctly clk_get calling clk_get_sys with driver
name. So dev in in CLK macro must be same as driver name. And
because in cclock3xxx_data.c is dev id "omap_rng" and there is
already driver with name "omap_rng", I need to rename dev in
cclock3xxx_data.c to get new omap3-rom-rng driver working.
Or if you know better way how to do it, let me know.
