rtc: pcf85063: support loading quartz-load capacitance from device tree2026-06-05T16:14:24ZAlexander Feilkealexander.feilke@ew.tq-group.com2026-05-22T15:39:27Zurn:sha1:d8f535cd8f7cb5f9231f91a3307895db7c9f9552
Use previously ignored quartz-load-femtofarads property from device tree
to set load capacitance. If missing, leave the device unconfigured
as a default might have been set. force_cap is left out for now but
can be retrofitted in the future as there may be different hardware
without the 12.500pF flag.

Supported devices:
- generic PCF85063 / PCF85063TP (no alarm regs)
- PCF85063A / PCF85073A (alarm regs)
Tested with TQMa8MPxL SOM from TQ-Systems GmbH.
Also add missing .data field to rv8263 which represents the number
of available registers (= linux `pcf85063_config.max_register + 1`).

The rtc_time documentation in rtc_def.h notes a differences
to the common "struct time" that specifies tm_mon as 1 ... 12
and tm_year as year since 0. Also trim register values to valid bits.

Add support for the Microcrystal RV8263 and compatible RTCs. The
driver's name was taken from linux. It should work with any NXP PCF85063
compatible RTCs. It was tested with a RV8263.
