Hi Abhishek, > QCA_ROME sometimes gets into a state where it is unresponsive to > commands. Since it doesn't have support for a reset gpio, reset the usb > port when this occurs instead. > > Signed-off-by: Abhishek Pandit-Subedi <abhishekpandit@xxxxxxxxxxxx> > --- > On Chromebooks with this chipset, we encountered cmd_timeout after > running suspend stress test for hundreds of iterations.
