The RTC core now has error messages in case of registration failure, there is no need to have other messages in the drivers. Link: https://lore.kernel.org/r/20191016201626.31309-3-alexandre.belloni@bootlin.comSigned-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

SGI Octane (IP30) doesn't have RTC register directly mapped into CPU address space, but accesses RTC registers with an address and data register. This is now supported by additional access functions, which are selected by a new field in platform data. Removed plat_read/plat_write since there is no user and their usage could introduce lifetime issue, when functions are placed in different modules.

If the RTC HW returns an invalid time, the rtc_year_days() call would crash. This patch adds error logging in this situation, and removes the tm_yday and tm_wday calculations. These fields should not be relied upon by userspace according to man rtc, and thus we don't need to calculate them.

Alexandre Belloni authored
The comment in the probe function stating that it disables oscillator stop detection and glitch filtering is incorrect as it sets bits 3 and 4 while it should be setting 5 and 6 to achieve that. Then, it is safe to assume that the oscillator failure detection is actually enabled. Properly handle oscillator failures by returning -EINVAL when the time and date are know to be incorrect and reset the flag when the time is set.

For rtc drivers where rtc->range_max is set U64_MAX, like the PS3 rtc, rtc_valid_range() always returns -ERANGE. This is because the local variable range_max has type time64_t, so the test if (time < range_min || time > range_max) return -ERANGE; becomes (time < range_min || time > -1), which always evaluates to true. timeu64_t should be used, since it's the type of rtc->range_max.
