rtc: s3c: Document in binding that only s3c6410 needs a src clk

2016-03-28T22:17:31+00:00

The S3C binding doc says that the RTC and RTC source clocks are required but the S3C driver supports different HW IP and only the s3c6410 needs a source clock. Fix the binding explaining that the source clock is only needed for the s3c6410-rtc compatible controller.

rtc: s3c: Document required clocks in the DT binding

2016-02-12T22:16:31+00:00

The S3C Real Time Clock driver requires the clock and source clock to be defined in the device node but that requirement is not documented. Signed-off-by: Javier Martinez Canillas Signed-off-by: Rob Herring

ARM: dts: Use s3c6410-rtc instead of exynos3250-rtc for exynos3250/4415

2015-05-17T01:51:32+00:00

Mark "samsung,exynos3250-rtc" compatible as deprecated because it duplicates the "samsung,s3c6410-rtc". Use "samsung,s3c6410-rtc" on Exynos3250 and Exynos4415 boards. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Chanwoo Choi Reviewed-by: Javier Martinez Canillas Signed-off-by: Kukjin Kim

rtc: s3c: add support for RTC of Exynos3250 SoC

2014-10-14T00:18:17+00:00

Add support for RTC of Exynos3250 SoC. The Exynos3250 needs source clock(32.768KHz) for RTC block. If source clock of RTC is registerd on clock list of common clk framework, Exynos RTC drvier have to control this clock. Clock list for s3c-rtc device: - rtc : CLK_RTC of CLK_GATE_IP_PERIR is gate clock for RTC. - rtc_src : XrtcXTI is 32.768.kHz source clock for RTC. (XRTCXTI: Specifies a clock from 32.768 kHz crystal pad with XRTCXTI and XRTCXTO pins. RTC uses this clock as the source of a real-time clock.)
