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. Mike/Stephen is this what you envisioned? It seems to work, but I currently don't have a setup that requires the 32khz clock early so that part isn't really tested. The probe deferral seems to work for the RTC: [ 3.386861] lpc24xx-rtc 40046000.rtc: error getting rtc clock [ 6.737615] lpc24xx-rtc 40046000.rtc: rtc core: registered lpc24xx-rtc as rtc0 Changes since v1: - Split driver with one early init and one platform driver probe. Based on v4.5-rc1.
