[PATCH 14/20] phy: qcom-qmp-usb: increase status polling period

From: Johan Hovold
Date: Wed Oct 12 2022 - 04:51:04 EST


It typically takes between one and two milliseconds for the PHY to
become ready after starting it. Increase the tight 3--10 us polling
period to the more reasonable 51--200 us.
