rtc: s3c: Add s3c_rtc_{enable/disable}_clk in s3c_rtc_setfreq()

2016-08-20T16:09:27+00:00

commit 70c96dfac0e231424e17743bd52f6cd2ff1f2439 upstream. As per code flow s3c_rtc_setfreq() will get called with rtc clock disabled and in set_freq we perform h/w registers read/write, which results in a kernel crash on exynos7 platform while probing rtc driver. Below is code flow: s3c_rtc_probe() clk_prepare_enable(info->rtc_clk) // rtc clock enabled s3c_rtc_gettime() // will enable clk if not done, and disable it upon exit s3c_rtc_setfreq() //then this will be called with clk disabled This patch take cares of such issue by adding s3c_rtc_{enable/disable}_clk in s3c_rtc_setfreq().

rtc: max77686: Properly handle regmap_irq_get_virq() error code

2016-05-04T21:48:52+00:00

commit fb166ba1d7f0a662f7332f4ff660a0d6f4d76915 upstream. The regmap_irq_get_virq() can return 0 or -EINVAL in error conditions but driver checked only for value of 0. This could lead to a cast of -EINVAL to an unsigned int used as a interrupt number for devm_request_threaded_irq(). Although this is not yet fatal (devm_request_threaded_irq() will just fail with -EINVAL) but might be a misleading when diagnosing errors.

rtc: da9063: fix access ordering error during RTC interrupt at system power on

2015-12-20T12:39:29+00:00

This fix alters the ordering of the IRQ and device registrations in the RTC driver probe function. This change will apply to the RTC driver that supports both DA9063 and DA9062 PMICs. A problem could occur with the existing RTC driver if: A system is started from a cold boot using the PMIC RTC IRQ to initiate a power on operation. For instance, if an RTC alarm is used to start a platform from power off. The existing driver IRQ is requested before the device has been properly registered. i.e. ret = devm_request_threaded_irq() comes before rtc->rtc_dev = devm_rtc_device_register(); In this case, the interrupt can be called before the device has been registered and the handler can be called immediately. The IRQ handler da9063_alarm_event() contains the function call rtc_update_irq(rtc->rtc_dev, 1, RTC_IRQF | RTC_AF); which in turn tries to access the unavailable rtc->rtc_dev. The fix is to reorder the functions inside the RTC probe. The IRQ is requested after the RTC device resource has been registered so that get_irq_byname is the last thing to happen.
