From e7f37a7d16310d3c9474825de26a67f00983ebea Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Mon, 21 Oct 2024 15:46:25 +0300 Subject: [PATCH] clk: qcom: gcc-x1e80100: Fix USB MP SS1 PHY GDSC pwrsts flags Allowing these GDSCs to collapse makes the QMP combo PHYs lose their configuration on machine suspend. Currently, the QMP combo PHY driver doesn't reinitialise the HW on resume. Under such conditions, the USB SuperSpeed support is broken. To avoid this, mark the pwrsts flags with RET_ON. This has been already done for USB 0 and 1 SS PHY GDSCs, Do this also for the USB MP SS1 PHY GDSC config. The USB MP SS0 PHY GDSC already has it.
