Subject: [PATCH 11/13] usb: imx-usb-phy: Add delay
Date: Wed,  6 May 2020 10:17:14 +0200	[thread overview]
Message-ID: <20200506081716.20143-11-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200506081716.20143-1-s.hauer@pengutronix.de>

The imx-usb-phy needs a small delay on i.MX28, otherwise the
stmp_reset_block() fails. Add this delay unconditionally as it doesn't
seem to be worth it to limit the delay on this platform.
