Subject: [PATCH] Modified imx7d-sdb.dts file so that VLDO4 provides 2.8V for MIPI CSI/DSI
From: Gautam Bhat <mindentropy@...il.com>
* According to mx7sabresd schematics the MIPI CSI/DSI voltage rails
should be 2.8V but the voltage provided is a maximum of 3.3V and
minimum of 1.8V. Providing such a higher voltage might damage the
peripherals and violates the schematic settings.
