The imx SC api strongly assumes that messages are composed out of 4-bytes words but some of our message structs have odd sizeofs. This produces many oopses with CONFIG_KASAN=y. Fix by marking with __aligned(4). Fixes: a3094fc1 ("rtc: imx-sc: add rtc alarm support") Signed-off-by:

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:

The RTC IRQ is requested before the struct rtc_device is allocated, this may lead to a NULL pointer dereference in the IRQ handler. To fix this issue, allocating the rtc_device struct before requesting the RTC IRQ using devm_rtc_allocate_device, and use rtc_register_device to register the RTC device. Also remove the unnecessary error message as the core already prints the info. Link: https://lore.kernel.org/r/20200311223956.51352-1-alexandre.belloni@bootlin.com Signed-off-by:

Some boards, like OrangePi PC2 (H5), OrangePi Plus 2E (H3) and Tanix TX6 (H6) don't have external 32kHz oscillator. Till H6, it didn't really matter if external oscillator was enabled because HW detected error and fall back to internal one. H6 has same functionality but it's the first SoC which have "auto switch bypass" bit documented and always enabled in driver. This prevents RTC to work correctly if external crystal is not present on board. There are other side effects - all peripherals which depends on this clock also don't work (HDMI CEC for example). Make clocks property optional. If it is present, select external oscillator. If not, stay on internal. Signed-off-by:
