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.

* Samsung's S3C Real Time Clock controller
|
|
|
|
Required properties:
|
|
- compatible: should be one of the following.
|
|
* "samsung,s3c2410-rtc" - for controllers compatible with s3c2410 rtc.
|
|
* "samsung,s3c2416-rtc" - for controllers compatible with s3c2416 rtc.
|
|
* "samsung,s3c2443-rtc" - for controllers compatible with s3c2443 rtc.
|
|
* "samsung,s3c6410-rtc" - for controllers compatible with s3c6410 rtc.
|
|
* "samsung,exynos3250-rtc" - (deprecated) for controllers compatible with
|
|
exynos3250 rtc (use "samsung,s3c6410-rtc").
|
|
- reg: physical base address of the controller and length of memory mapped
|
|
region.
|
|
- interrupts: Two interrupt numbers to the cpu should be specified. First
|
|
interrupt number is the rtc alarm interrupt and second interrupt number
|
|
is the rtc tick interrupt. The number of cells representing a interrupt
|
|
depends on the parent interrupt controller.
|
|
- clocks: Must contain a list of phandle and clock specifier for the rtc
|
|
clock and in the case of a s3c6410 compatible controller, also
|
|
a source clock.
|
|
- clock-names: Must contain "rtc" and for a s3c6410 compatible controller,
|
|
a "rtc_src" sorted in the same order as the clocks property.
|
|
|
|
Example:
|
|
|
|
rtc@10070000 {
|
|
compatible = "samsung,s3c6410-rtc";
|
|
reg = <0x10070000 0x100>;
|
|
interrupts = <44 0 45 0>;
|
|
clocks = <&clock CLK_RTC>, <&s2mps11_osc S2MPS11_CLK_AP>;
|
|
clock-names = "rtc", "rtc_src";
|
|
};
