Subject: [PATCH v2 2/4] arm64: dts: qcom: sm8750: Set snps,resume-hs-terminations for USB controller
Date: Sun, 18 Oct 2026 19:15:45 -0700	[thread overview]
Message-ID: <20261019021547.1694088-3-peter.chen@oss.qualcomm.com> (raw)
In-Reply-To: <20261019021547.1694088-1-peter.chen@oss.qualcomm.com>

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].

Fixes: 7a5bb9f60527 ("arm64: dts: qcom: sm8750: Add USB support to SM8750 SoCs")
