Yes the FIQs are only accessible in the secure mode starting with
omap2. So that also means omap3, 4, 5.

It could be that I am misreading something, but RX51 is OMAP3.

Take a look at the omap3xxx_clks in cclock3xxx_data.c.
Note how some entries

Why is this using clk_get_sys when it should be using clk_get() with the
platform device?

This driver provides kernel-side support for the Random Number
Generator hardware found on OMAP34xx processors.
This driver is included in Maemo 2.6.28 kernel used on Nokia N900.
I fixed driver to work with 3.8 kernel and added platform_driver
code to autoload it on omap3 devices.
