[PATCH v1 0/3] rtc: mt6359: Cleanup and support start-year property

From: AngeloGioacchino Del Regno
Date: Mon Sep 23 2024 - 06:00:37 EST


This series adds support for the start-year property and removes the
custom handling of the RTC_MIN_YEAR_OFFSET (which is, effectively, doing
the exact same).

The start_secs timestamp was set to match the previous one from the
custom behavior so that there is no time drift on any device after
applying this.

While at it, a cleanup to use the Day-of-Week HW register instead of
manually calculating tm_wday was also performed.

For the bindings commit, this series goes on top of the MT6397 schema
conversion from Macpaul Lin [1].

This series was tested on a MT8195 Cherry Tomato Chromebook.
