Add optional reset and standby gpios. The reset gpio is used to reset the chip in power_on(). The standby gpio is not used currently. It is just unset, so the chip is not in standby.

* Aptina 1/3-Inch WVGA CMOS Digital Image Sensor
|
|
|
|
The Aptina MT9V032 is a 1/3-inch CMOS active pixel digital image sensor with
|
|
an active array size of 752H x 480V. It is programmable through a simple
|
|
two-wire serial interface.
|
|
|
|
Required Properties:
|
|
|
|
- compatible: value should be either one among the following
|
|
(a) "aptina,mt9v022" for MT9V022 color sensor
|
|
(b) "aptina,mt9v022m" for MT9V022 monochrome sensor
|
|
(c) "aptina,mt9v024" for MT9V024 color sensor
|
|
(d) "aptina,mt9v024m" for MT9V024 monochrome sensor
|
|
(e) "aptina,mt9v032" for MT9V032 color sensor
|
|
(f) "aptina,mt9v032m" for MT9V032 monochrome sensor
|
|
(g) "aptina,mt9v034" for MT9V034 color sensor
|
|
(h) "aptina,mt9v034m" for MT9V034 monochrome sensor
|
|
|
|
Optional Properties:
|
|
|
|
- link-frequencies: List of allowed link frequencies in Hz. Each frequency is
|
|
expressed as a 64-bit big-endian integer.
|
|
- reset-gpios: GPIO handle which is connected to the reset pin of the chip.
|
|
- standby-gpios: GPIO handle which is connected to the standby pin of the chip.

reg = <0x5c>;
|
|
|
|
port {
|
|
mt9v032_out: endpoint {
|
|
link-frequencies = /bits/ 64
