[PATCH 04/20] ARM: dts: imx6-sabrelite: add OV5642 and OV5640 camera sensors

From: Steve Longerbeam
Date: Thu Dec 29 2016 - 17:43:56 EST

Enables the OV5642 parallel-bus sensor, and the OV5640 MIPI CSI-2 sensor.
Both hang off the same i2c2 bus, so they require different (and non-
default) i2c slave addresses.

The OV5642 connects to the parallel-bus mux input port on ipu1_csi0_mux.

The OV5640 connects to the input port on the MIPI CSI-2 receiver on
mipi_csi. It is set to transmit over MIPI virtual channel 1.

Note there is a pin conflict with GPIO6. This pin functions as a power
input pin to the OV5642, but ENET uses it as the h/w workaround for
erratum ERR006687, to wake-up the ARM cores on normal RX and TX packet
done events (see 6261c4c8). So workaround 6261c4c8 is reverted here to
support the OV5642, and the "fsl,err006687-workaround-present" boolean
also must be removed. The result is that the CPUidle driver will no longer
allow entering the deep idle states on the sabrelite.
