Subject: [PATCH v2] ARM: dts: imx7d-sdb: Set VLDO4 outpt to 2.8V for MIPI CSI/DSI
Date: Sat,  1 Jul 2017 13:09:11 +0530	[thread overview]
Message-ID: <20170701073911.7338-1-mindentropy@gmail.com> (raw)
In-Reply-To: <CAOMZO5A41QFoJsC2ST1kvpCOs3-unzHDrqXshHa=2ShWWCOyZg@mail.gmail.com>

From: Gautam Bhat <mindentropy@gmail.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.
