Subject: [PATCH v1 0/2] rtc: Add support for MT6685 RTC

This series adds a driver for the Real Time Clock found in the MT6685
Clock/PM IC.

This chip has been used on a number of different MediaTek platforms
from around 2023 to the latest ones released in 2025 - and on both
Smartphones (Helio and Dimensity), Chromebooks (Kompanio Ultra) and
Genio boards.

This was tested on a MT8196 (Kompanio Ultra) Chromebook.

NOTE: This series depends on series [1] "SPMI: Implement sub-devices
and migrate drivers"
