From 7612890b9df8f3f4f9b4fd39d988a5afd97aa3e7 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 12 Oct 2022 10:49:56 +0200 Subject: [PATCH] phy: qcom-qmp-usb: increase status polling period 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.
