Subject: [PATCH AUTOSEL 6.5 04/18] dt-bindings: phy: qcom,snps-eusb2-repeater: Add magic tuning overrides
Date: Tue, 7 Nov 2023 18:22:59 -0500 [thread overview]
Message-ID: <20231107232330.3776001-4-sashal@kernel.org> (raw)
In-Reply-To: <20231107232330.3776001-1-sashal@kernel.org>
From: Konrad Dybcio <konrad.dybcio@linaro.org>
[ Upstream commit c20b59b2996c89c4f072c3312e6210528a298330 ]
The EUSB2 repeater requires some alterations to its init sequence,
depending on board design.
Add support for making the necessary changes to that sequence to make USB
functional on SM8550-based Xperia 1 V.
They all have lackluster description due to lack of information.
