Subject: [U-Boot] [PATCH v2 11/14] usb: ehci-msm: Add init_after_reset for CI_UDC
Date: Fri, 21 Sep 2018 13:35:53 +0300	[thread overview]
Message-ID: <20180921103555.16240-12-ramon.fried@gmail.com> (raw)
In-Reply-To: <20180921103555.16240-1-ramon.fried@gmail.com>

MSM uses the chipidea controller IP, however it requires
to reinit the phy after controller reset. in EHCI mode there's a
dedicated callback for it.
In device mode however there's no such callback.
Add implementaion of ci_init_after_reset() to implement the above
requirement in case CI_UDC driver is used.
