Subject: [PATCH v3 2/2] ARM: da850/omap-l138: Add EVM specific code for VPIF to work
From: Manjunath Hadli <manjunath.hadli@...com>
Include the expander settings to select VPIF peripheral on
UI card and add registration call in EVM init. Also add platform
data to configure display and capture devices.
