phy: qcom: qmp-combo: correct bias0_en programming
It seems the commita2e927b0e5("phy: qcom-qmp-combo: Add sc8280xp USB/DP combo phys") contained a typo for selecting bias0_en values. First, bias0_en and bias1_en are expected to be symmetrical, and then the vendor driver also uses `flipped : 0x3E : 0x15` statement for bias0_en. Correct bias0_en programming to follow this. Fixes:49742e9eda("phy: qcom-qmp-combo: Add support for SM8550") Fixes:a2e927b0e5("phy: qcom-qmp-combo: Add sc8280xp USB/DP combo phys") Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://lore.kernel.org/r/20230621153317.1025914-2-dmitry.baryshkov@linaro.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
