2019-12-23rtc: hym8563: Return -EINVAL if the time is known to be invalidPaul Kocialkowski
The current code returns -EPERM when the voltage loss bit is set. Since the bit indicates that the time value is not valid, return -EINVAL instead, which is the appropriate error code for this situation.

2019-12-10rtc: ds1343: Do not hardcode SPI mode flagsLinus Walleij
The current use of mode flags to us SPI_MODE_3 and SPI_CS_HIGH is fragile: it overwrites anything already assigned by the SPI core. Change it thusly: - Just |= the SPI_MODE_3 so we keep other flags - Assign ^= SPI_CS_HIGH since we might be active high already, and that is usually the case with GPIOs used for chip select, even if they are in practice active low. Add a comment clarifying why ^= SPI_CS_HIGH is the right choice here.
