In reply to this mail you will find: - a single patch on top of the 4 original patches, fixing the problems sylwester reported - a v4 of the original series including the fixes to the problems, based on the code that you have in your rtc-branch Please pick the apropriate variant to fix the problem :-) Heiko
Similar to the ADC the RTC of S3C2443 and S3C2416/2450 has some slight variances when compared to the existing types. This series adds support for those SoCs. As with the ADC patches, these changes where tested on S3C2416 hardware. The S3C2443 quirks are a subset of those and are done according to the datasheet, but not tested on real hardware (as I do not own a S3C2443 device). changes since v3: fixes missing "," in s3c_rtc_dt_match and wrong handling of the of_device_id.data property, as reported-by Sylwester Nawrocki changes since v2: remove obsolete constants in register cleanup changes since v1: address comments from Thomas Abraham, reducing number of ifdefs and duplicate code Heiko Stuebner (4): ARM: SAMSUNG: cleanup of rtc register definitions rtc-s3c: make room for more variants in devicetree block rtc-s3c: add variants for S3C2443 and S3C2416 ARM: S3C2443/S3C2416: add s3c_rtc_setname and rename rtc devices arch/arm/mach-s3c2416/s3c2416.c | 2 + arch/arm/mach-s3c2443/s3c2443.c | 2 + arch/arm/plat-samsung/include/plat/regs-rtc.h | 81 +++++++++++++------------ arch/arm/plat-samsung/include/plat/rtc-core.h | 27 ++++++++ drivers/rtc/rtc-s3c.c | 71 ++++++++++++++++++---- 5 files changed, 131 insertions(+), 52 deletions(-) create mode 100644 arch/arm/plat-samsung/include/plat/rtc-core.h
