This driver uses the century bit of this RTC in the opposite way Linux does. From Linux's rtc-pcf8563.c: /* * The meaning of MO_C bit varies by the chip type. * From PCF8563 datasheet: this bit is toggled when the years * register overflows from 99 to 00 * 0 indicates the century is 20xx * 1 indicates the century is 19xx * From RTC8564 datasheet: this bit indicates change of * century. When the year digit data overflows from 99 to 00, * this bit is set. By presetting it to 0 while still in the * 20th century, it will be set in year 2000, ... * There seems no reliable way to know how the system use this * bit. So let's do it heuristically, assuming we are live in * 1970...2069. */ As U-Boot's PCF8563 driver does not say it is supposed to support the RTC8564, make this driver compatible with Linux's by giving the opposite meaning to the century bit.
