Subject: [PATCH] drm/msm/dsi: Updata LNn_CFG4 register settings for 28nm PHY
Date: Fri, 11 Sep 2015 15:56:09 -0400 [thread overview]
Message-ID: <1442001369-12043-1-git-send-email-hali@codeaurora.org> (raw)
In-Reply-To: <1442000412-8790-1-git-send-email-hali@codeaurora.org>
The current settings for 28nm PHY data lane CFG4 registers do
not work with certain panels. This change is to modify them to
hw recommended values.
