From: Konrad Dybcio Date: Wed, 13 Sep 2023 09:53:23 +0000 (+0200) Subject: dt-bindings: phy: qcom,snps-eusb2-repeater: Add magic tuning overrides X-Git-Tag: v6.6.17~2921 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=de77703a0a81368a611598c89d67eaafe8c0fa78;p=platform%2Fkernel%2Flinux-rpi.git dt-bindings: phy: qcom,snps-eusb2-repeater: Add magic tuning overrides [ 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.
