Subject: [PATCH v3 2/2] arm64: dts: qcom: sa8775p: Remove max link speed property for PCIe EP
Date: Sun, 25 May 2025 11:27:18 +0530 [thread overview]
Message-ID: <20250525-update_phy-v3-2-5b315cd39993@quicinc.com> (raw)
In-Reply-To: <20250525-update_phy-v3-0-5b315cd39993@quicinc.com>
From: Mrinmay Sarkar <mrinmay.sarkar@oss.qualcomm.com>
The maximum link speed was previously restricted to Gen3 due to the
absence of Gen4 equalization support in the driver.
Add change to remove max link speed property, Since Gen4 equalization
support has already been added into the driver.
