fix: rtc: fixed rtc_set according to FE-3124064 (HW ERRATA 3124064)
According to FE-3124064:
- Description:
The device supports CPU write and read access to the RTC Time register
However, due to this erratum, Write to RTC TIME register may fail.
Read from RTC TIME register may fail.
Workaround:
Before writing to RTC TIME register, issue a dummy
write of 0x0 twice to RTC Status register.
RTC TIME register should be read twice, the second
read will return a proper value.
Configure maximum value (0x3FF) in write clock period in
RTC Mbus Bridge Timing Control register.
- Fixed rtc_set according to the workaround (write 0x0 to status register
twice before writing to RTC time register)
- Configure maximum value (0x3FF) in write clock period in
RTC Mbus Bridge Timing Control register.
- Fixed JIRA:1909, 1955
