+Subject: [PATCH 3/3] ARM: dts: imx: ventana: Allow HDMI and LVDS to work
+ simultaneously
+
+Currently it is not possible to have HDMI and LVDS working simultaneously,
+because both ports try to use PLL5.
+
+Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be
+driven from independent sources.
+
+With this change the LDB pixel clock goes to 68.57 MHz, which is still
+within the valid range for the displays supported by the Ventana boards.
