Merge tag 'fixes-for-v5.2-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus
Felipe writes: usb: fixes for v5.2-rc5 A single fix to take into account the PHY width during initialization of dwc2 driver. This change allows deviceTree to pass PHY width if necessary. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> * tag 'fixes-for-v5.2-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb: usb: dwc2: Use generic PHY width in params setup
