8 title: Omnivision OV02A10 CMOS Sensor
11 - Dongchun Zhu <dongchun.zhu@mediatek.com>
14 The Omnivision OV02A10 is a low-cost, high performance, 1/5-inch, 2 megapixel
15 image sensor, which is the latest production derived from Omnivision's CMOS
16 image sensor technology. Ihis chip supports high frame rate speeds up to 30fps
17 @ 1600x1200 (UXGA) resolution transferred over a 1-lane MIPI interface. The
18 sensor output is available via CSI-2 serial data output.

35 External clock for the sensor.
41 Frequency of the eclk clock in Hz.
45 Definition of the regulator used as Digital I/O voltage supply.
49 Definition of the regulator used as Analog voltage supply.
53 Definition of the regulator used as Digital core voltage supply.
57 Must be the device tree identifier of the GPIO connected to the
58 PD_PAD pin. This pin is used to place the OV02A10 into standby mode
59 or shutdown mode. As the line needs to be high for the powerdown mode
60 to be active, it should be marked GPIO_ACTIVE_HIGH.
65 Must be the device tree identifier of the GPIO connected to the
66 RST_PD pin. If specified, it will be asserted during driver probe.
67 As the line needs to be low for the reset to be active, it should be
68 marked GPIO_ACTIVE_LOW.
