2023-02-16phy: qcom: phy-qcom-snps-eusb2: Add support for eUSB2 repeaterNeil Armstrong1-1/+18
For USB 2.0 compliance, eUSB2 needs a repeater. The PHY needs to initialize and reset it. So add repeater support Co-developed-by: Abel Vesa <abel.vesa@linaro.org> Signed-off-by: Abel Vesa <abel.vesa@linaro.org> Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org> Link: https://lore.kernel.org/r/20230208190200.2966723-6-abel.vesa@linaro.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
