From mboxrd@z Thu Jan 1 00:00:00 1970 From: mindentropy@gmail.com (mindentropy) Date: Sat, 1 Jul 2017 13:09:11 +0530 Subject: [PATCH v2] ARM: dts: imx7d-sdb: Set VLDO4 outpt to 2.8V for MIPI CSI/DSI In-Reply-To: References: Message-ID: <20170701073911.7338-1-mindentropy@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Gautam Bhat * 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.
