[PATCH v1 0/5] add quartz load support to NXP rtc drivers

[Sam Ravnborg <sam@ravnborg.org>]

The current rtc drivers for NXP pcf8523 and pcf85063
have different configuration of the quartz load.

pcf8523 hardcode the quartz load to 12.5 Pf
pcf85063 uses the reset default of 7 pF

Introduce a new property to the bindings for the two
rtc devices to specify if the quartz load is 12.5 pF.

Update all in-kernel DT files using the pcf8523 to specify this property.
And finally update the drivers to support the property.

NOTE:
This has the side-effect that any users of the
pcf8523 driver using out-of-tree DTS files needs to
add the new property to get the same behaviour as before.
