2020-11-19rtc: rework rtc_register_device() resource managementBartosz Golaszewski
rtc_register_device() is a managed interface but it doesn't use devres by itself - instead it marks an rtc_device as "registered" and the devres callback for devm_rtc_allocate_device() takes care of resource release. This doesn't correspond with the design behind devres where managed structures should not be aware of being managed. The correct solution here is to register a separate devres callback for unregistering the device. While at it: rename rtc_register_device() to devm_rtc_register_device() and add it to the list of managed interfaces in devres.rst. This way we can avoid any potential confusion of driver developers who may expect there to exist a corresponding unregister function.

2020-05-11rtc: ingenic: Reset regulator register in probePaul Cercueil
The regulator register specifies how many input clock cycles (minus one) are contained in one tick of the 1 Hz clock. Since this register can contain bogus values after the system boots, it needs to be reset in the probe register, otherwise the RTC may count way to slow or way too fast.

2020-03-24rtc: jz4740: Add support for JZ4760 SoCPaul Cercueil
The WENR feature (set a magic value to enable RTC registers read-write) first appeared on the JZ4760; the JZ4780 came much later. Since it would be dangerous to specify a newer SoC's compatible string as the fallback of an older SoC's compatible string, we add support for the "ingenic,jz4760-rtc" compatible string in the driver. This will permit to support the JZ4770 by having: compatible = "ingenic,jz4770-rtc", "ingenic,jz4760-rtc"; Instead of doing: compatible = "ingenic,jz4770-rtc", "ingenic,jz4780-rtc"; Signed-off-by: Paul Cercueil <paul@crapouillou.net> Link: https://lore.kernel.org/r/20200311182318.22154-1-paul@crapouillou.net Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

Yet we assign the result of platform_get_irq() to it. platform_get_irq() may return a negative error code and the code checks for this condition by checking if 'irq' is less than zero.
