Subject: [PATCH v4 01/14] phy: Add LVDS configuration options
Date: Thu, 18 Feb 2021 11:41:42 +0800 [thread overview]
Message-ID: <1613619715-28785-2-git-send-email-victor.liu@nxp.com> (raw)
In-Reply-To: <1613619715-28785-1-git-send-email-victor.liu@nxp.com>
This patch allows LVDS PHYs to be configured through
the generic functions and through a custom structure
added to the generic union.
The parameters added here are based on common LVDS PHY
implementation practices. The set of parameters
should cover all potential users.
