Would be interesting to support the v2 also, though! Sorry for highjacking the thread, but if one of you is still actively working on lpc32xx stuff, would you be able to convert arch/arm/mach-lpc32xx/clock.c to a proper driver for drivers/clk? I'd like to see the platform get converted to use ARCH_MULTIPLATFORM eventually, and this is the main showstopper. Arnd ^ permalink raw reply [flat|nested] 7+ messages in thread
