v3 of this patch got "Reviewed-by" from Rob Herring.
But unfortunately, as one more property had to be added afterwards, my understanding
is that that "Reviewed-by" doesn't apply to v4.
Thanks,
Andrey

+description: |-
+ The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor
+ with an active array size of 3280H x 2464V. It is programmable through
+ I2C interface. The I2C address is fixed to 0x10 as per sensor data sheet.
+ Image data is sent through MIPI CSI-2, which is configured as either 2 or
+ 4 data lanes.
