There are several arch-specific RTC drivers that can be successfully compiled on other platforms. Add a COMPILE_TEST dependency for those. Signed-off-by: NAlexandre Belloni <alexandre.belloni@free-electrons.com> Acked-by: NGeert Uytterhoeven <geert@linux-m68k.org>

There are four architectures using this driver, but since we can build it with COMPILE_TEST, we should try dealing with the absence of the asm/rtc.h header file, to avoid getting a build error: drivers/rtc/rtc-generic.c:12:21: fatal error: asm/rtc.h: No such file or directory This creates an alternative use of the driver, allowing architectures to pass a set of rtc_class_ops in platform data. We can convert the four architectures to use this and then remove the original code.

The time and date register of the pcf8223 are undefined after a power reset. Properly handle the OS bit and return -EINVAL when that bit is set. It is properly removed when setting the time. This solves an issue where the time and date may be valid for rtc_valid_tm() but is not the current time. Signed-off-by: NAlexandre Belloni <alexandre.belloni@free-electrons.com>

The driver uses the MODULE_ALIAS() macro to export a platform module alias to allow the module to be autoloaded if the device is registered using the legacy platform registration mechanism but the driver is always used by OF only machines so the alias is not needed and should just be removed.

Lets remove the modular code that is essentially orphaned, so that when reading the code there is no doubt it is builtin-only. We don't replace module.h with init.h since the file does need to know what a struct module is. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

When setting a new time/date the RTC's clock must be stopped first, in order to write the time/date registers in an atomic manner. So, this change stops the clock first and then writes the time/date registers and the clock control register (to re-enable the clock) in one turn.

By using i2c_smbus_read_i2c_block_data() the code is now much simpler. While at it: when reading the RTC's seconds register, all time/date registers are frozen until the RTC's year register is read. So it is important to read all time/date registers in one turn to not lose a second event. Make it more clear why the read must happen in this way.

A number of rtc devices, such as the NXP pcf2123 include a facility to adjust the clock in order to compensate for temperature or a crystal, capacitor, etc, that results in the rtc clock not running at exactly 32.768 kHz. Data sheets I have seen refer to this as a clock offset, and measure it in parts per million, however they often reference ppm to 2 digits of precision, which makes integer ppm less than ideal. We use parts per billion, which more than covers the precision needed and works nicely within 32 bits Signed-off-by: NJoshua Clayton <stillcompiling@gmail.com> Signed-off-by: NAlexandre Belloni <alexandre.belloni@free-electrons.com>

To make RTC block of MAX77686/MAX77802 as independent driver, move the registration of i2c device, regmap for register access and irq_chip for interrupt support inside the RTC driver.
