During recent test on Exynos4210 based Origen board, I observed RTC1 probe is failing giving following error message: [ 2.195817] s3c-rtc 10070000.rtc: failed to find rtc source clock [ 2.200475] s3c-rtc: probe of 10070000.rtc failed with error -2 [ 2.206597] i2c /dev entries driver This is mainly because S3C-RTC expects two clocks "rtc" and "rtc_src". In case of Origen board this second clock is supplied by MAX8997 clock oscillator. This patch series modified MAX8997 MFD driver for supporting regmap, and adds max8997-clk driver. Also it documentation where-ever required and extends RTC node in exynos4210-origen.dts for supporting both clocks. After this patch series, RTC is getting probed properly on Origen board. This patch series is tested for SMP boot on Origen board.
