2019-12-10usb: common: usb-conn-gpio: Don't log an error on probe deferralBryan O'Donoghue
This patch makes the printout of the error message for failing to get a VBUS regulator handle conditional on the error code being something other than -EPROBE_DEFER. Deferral is a normal thing, we don't need an error message for this.

2019-09-03usb: common: add USB GPIO based connection detection driverChunfeng Yun
Due to the requirement of usb-connector.txt binding, the old way using extcon to support USB Dual-Role switch is now deprecated when use Type-B connector. This patch introduces a USB GPIO based connection detection driver, used to support Type-B connector which typically uses an input GPIO to detect USB ID pin, and try to replace the function provided by the extcon-usb-gpio driver Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Tested-by: Nagarjuna Kristam <nkristam@nvidia.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Link: https://lore.kernel.org/r/1567070558-29417-11-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
