The rtc-sh.c code wants to have a number at the end. So if I just put "rtc" as the clock name, it does not find it. Again, I didn't want to break any SH builds, so I just changed the DT to match the driver.
[ from the rtc-sh.c code ]
clk_id = pdev->id;
/* With a single device, the clock id is still "rtc0" */
if (clk_id < 0)
clk_id = 0;
snprintf(clk_name, sizeof(clk_name), "rtc%d", clk_id);
rtc->clk = devm_clk_get(&pdev->dev, clk_name);
if (IS_ERR(rtc->clk)) {
/*
* No error handling for rtc->clk intentionally, not all
* platforms will have a unique clock for the RTC, and
* the clk API can handle the struct clk pointer being
* NULL.
*/
rtc->clk = NULL;
}
clk_enable(rtc->clk);
Cheers
Chris
