I tested PL175 on Timll Devkit3250 board with 4Mb NOR.

Right, this is in my plans. To avoid any mess in the controller driver,
mach-lpc32xx must be converted to common clock framework firstly, that's
what I'm doing at the moment, then I'll send the corresponding EMC
updates in lpc32xx.dtsi.

By the way I've tested your clocksource driver on LPC32xx and it works
fine, but again clean switching to it is not possible until LPC32xx
clocks are out of the common clock framework.
