description: |-
The Omnivision OV02A10 is a low-cost, high performance, 1/5-inch, 2 megapixel
image sensor, which is the latest production derived from Omnivision's CMOS
image sensor technology. Ihis chip supports high frame rate speeds up to 30fps
@ 1600x1200 (UXGA) resolution transferred over a 1-lane MIPI interface. The
sensor output is available via CSI-2 serial data output.

description:
Must be the device tree identifier of the GPIO connected to the
PD_PAD pin. This pin is used to place the OV02A10 into standby mode
or shutdown mode. As the line needs to be high for the powerdown mode
to be active, it should be marked GPIO_ACTIVE_HIGH.

description:
Must be the device tree identifier of the GPIO connected to the
RST_PD pin. If specified, it will be asserted during driver probe.
As the line needs to be low for the reset to be active, it should be
marked GPIO_ACTIVE_LOW.
