Summary0006470: Driver rtc-85263.c is not-selected/deprecated and can be replaced with rtc85363.c
Descriptionrtc-85263.c is not selected in defconfig (CONFIG_RTC_DRV_PCF85263).
rtc-85263.c is not mainline and comes from older F&S-Kernel versions.

rtc-85363.c is mainline and supports pcf85263.
The driver is currently selected (CONFIG_RTC_DRV_PCF85363).

The driver also supports properties for load_capacitance but the property name is different.

Currently the RTC is not setup correctly in all fsimx93 devicetrees.


My suggestion:

- Drop rtc-pcf85263.c and use rtc-85363.c
- Use "quartz-load-femtofarads" property in all devicetrees.
- Drop "quartz-load-capacitance"
- Drop or Implement "quartz-drive-strength"

Driver rtc-pcf85263.c has been removed.

Driver rtc-pcf85363.c has been supplemented with a property lookup for clk-out and drive strength
