dts: update to v4.16-rc1
Also includeded: ARM: dts: am33xx: do not delete no longer existing clocks Several clocks are removed from the am33xx dts files with v4.16-rc1. Remove the corresponding /delete-node/ directives aswell to avoid dtc breakage. Also included: ARM: dts: imx6qdl: SolidRun: Fix upstream include Upstream dts file way renamed, so change include name accordingly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

+* Omnivision OV7740 CMOS image sensor
+
+The Omnivision OV7740 image sensor supports multiple output image
+size, such as VGA, and QVGA, CIF and any size smaller. It also
+supports the RAW RGB and YUV output formats.
+
+The common video interfaces bindings (see video-interfaces.txt) should
+be used to specify link to the image data receiver. The OV7740 device
+node should contain one 'port' child node with an 'endpoint' subnode.
+
+Required Properties:
+- compatible: "ovti,ov7740".
+- reg: I2C slave address of the sensor.
+- clocks: Reference to the xvclk input clock.
+- clock-names: "xvclk".
+
+Optional Properties:
+- reset-gpios: Rreference to the GPIO connected to the reset_b pin,
+ if any. Active low with pull-ip resistor.
+- powerdown-gpios: Reference to the GPIO connected to the pwdn pin,
+ if any. Active high with pull-down resistor.
+
+Endpoint node mandatory properties:
+- remote-endpoint: A phandle to the bus receiver's endpoint node.
+
+Example:
+
