[PATCH v2 2/4] arm64: dts: qcom: sm8750: Set snps,resume-hs-terminations for USB controller

From: Peter Chen

Date: Sun Oct 18 2026 - 22:16:27 EST


The DWC3 controller on SM8750 is paired with the M31 eUSB2 PHY.
According to HPG, host-mode USB2 L2/L1 resume with this PHY, GUCTL1[10]
(RESUME_OPMODE_HS_HOST) must be set.

Set snps,resume-hs-terminations on the SM8750 USB controller. This makes
dwc3 core set GUCTL1[10].
