Subject: Re: [PATCH 6/9] Ufs: add PhyInit
Date: Fri, 6 Jan 2017 16:21:38 +0800	[thread overview]
Message-ID: <CAD6h2NT6xiaRsn4gGf7Bp9_LaFH9VJAupHKSLw6WJH2xpfubeA@mail.gmail.com> (raw)
In-Reply-To: <7F1BAD85ADEA444D97065A60D2E97EE5699A6014@SHSMSX101.ccr.corp.intel.com>

It's a bit hard to implement it in lower layer. Since PhyInit ()
should be executed
between UFS controller enabled and UicDmeLinkStartup command.

Best Regards
Haojian
