This patch set adds a clk driver for the low power clocks found in
the CREG block on lpc18xx. CREG is a collection of miscellaneous
configuration registers that can be accessed through a syscon
regmap interface. The clk driver makes it possible to setup and
enabled these two clocks.

This need to support peripherals like the internal RTC on the
lpc18xx platform.
I know this is many months old, but is this driver still
required? I can apply it to clk-next if so.
It is still needed for the internal RTC (rtc-lpc24xx) on lpc18xx. The
RTC uses a 1 kHz clock that is controlled in CREG (misc system regs).

Note; if you apply it you will most likely get a very trivial conflict
in drivers/clk/nxp/Makefile because clk-lpc32xx.c has been added since
these patches was sent.

Joachim Eastwood
