Subject: [PATCH] mfd: rtsx: Modify rts5249_optimize_phy
Date: Thu, 5 Sep 2013 17:45:38 +0800 [thread overview]
Message-ID: <1378374338-11455-1-git-send-email-wei_wang@realsil.com.cn> (raw)
From: Wei WANG <wei_wang@realsil.com.cn>
In some platforms, specially Thinkpad series, rts5249 won't be
initialized properly. So we need adjust some phy parameters to
improve the compatibility issue.
