[PATCH v2 3/3] arm64: dts: imx8mq-evk: add regulator-off-in-suspend for VGEN1/VGEN6

From: Joy Zou

Date: Fri Jul 31 2026 - 06:22:16 EST


VGEN1 and VGEN6 have no consumers and are not always-on. Mark them as
regulator-off-in-suspend to disable them properly during suspend and
reduce power consumption.

Changes in v2:
- The patch is aimed at reducing power consumption during suspend. It is
not related to the race condition. So remove the redundant wording so the
commit message is clearer.
- Link to v1: https://patch.msgid.link/20260716-b4-regulator-pf01-v1-0-8c1519d54bd4@xxxxxxxxxxx
