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. regards, Joachim Eastwood
