Subject: [v2 04/10] phy: Add HDMI configuration options
Date: Fri, 4 Nov 2022 14:44:54 +0800 [thread overview]
Message-ID: <ae34e5e10f8df1f6bc1b08286f43c8181a42dd2b.1667463263.git.Sandor.yu@nxp.com> (raw)
In-Reply-To: <cover.1667463263.git.Sandor.yu@nxp.com>
Allow HDMI PHYs to be configured through the generic
functions through a custom structure added to the generic union.
The parameters added here are based on HDMI PHY
implementation practices. The current set of parameters
should cover the potential users.
