From e726a9fdde2863697f885a8bef8af38c3c759eb3 Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Fri, 6 Nov 2015 14:40:32 -0800 Subject: [PATCH] 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.
