Code changes losely based on phy-meson-gxl-usb2.c Initially if we connect USB HDD at initial boot it get detected. but after that usb hotplug of USB HDD is broken. I did not observe and USB debug events messages to trace the root cause. Another issue I observed is increase of USB interrupts event even if there is not much activity on USB ports. I tried some clk changes but it did not workout for me. $ cat /proc/interrupts | grep usb 45: 0 0 0 0 GICv2 62 Level c9000000.usb, dwc2_hsotg:usb1 46: 17488032 0 0 0 GICv2 63 Level c9100000.usb, dwc2_hsotg:usb2 Thanks -Anand Anand Moon (8): phy: amlogic: meson8b-usb2: Use clock bulk to get clocks for phy phy: amlogic: meson8b-usb2: Use phy init callback function phy: amlogic: meson8b-usb2: Use phy exit callback function phy: amlogic: meson8b-usb2: Use phy set_mode callback function phy: amlogic: meson8b-usb2: Reorder phy poweroff callback function phy: amlogic: meson8b-usb2: Use phy reset callback function phy: amlogic: meson8b-usb2: Power off the PHY by putting it into reset mode. phy: amlogic: meson8b-usb2: don't log an error on -EPROBE_DEFER drivers/phy/amlogic/phy-meson8b-usb2.c | 159 +++++++++++++++++-------- 1 file changed, 109 insertions(+), 50 deletions(-)
