[PATCH 0/2] rtc: pcf85063: Add NXP PCA85074A support

From: Rodrigo Rea <rodrigo.rea@xxxxxxx>

Add support for the NXP PCA85074A real-time clock.

The PCA85074A uses the same register map as the PCA85073A and can
reuse the existing PCF85063A configuration. The series documents the
new compatible and adds the corresponding I2C and OF match entries.
No changes to the timekeeping or alarm implementation are needed.

Tested on i.MX91S and i.MX93 platforms.

Host-side validation:
- scripts/checkpatch.pl --strict
- git diff --check
- Driver object build with W=1, I2C, OF and COMMON_CLK enabled
- dt_binding_check for rtc/nxp,pcf85063.yaml
- Patch application against the base revision
