This patchset adds support for IMX219 CMOS image sensor from Sony.
Sony IMX219 is an 8MPix, 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. Image data are sent through MIPI CSI-2, which can be configured
as either 2 or 4 data lanes, but this driver currently only supports 2 lanes.
The currently supported resolutions are 3280x2464 @ 15fps, 1920x1080 @ 30fps
(cropped FOV), and 1640x1232 (2x2 binned) @ 30fps.
The driver has been tested with Raspberry Pi Camera Module v2 connected to
Raspberry Pi Zero W.
Changes since v2 [1]:
dt-bindings:
- "clock-names" property removed
- "xclr-gpios" property renamed to "reset-gpios"
- the camera-clk mode moved out of sensor device node
- "clock-lanes" property removed (the sensor doesn't support lane reordering)
- "clock-noncontinuous" description made more clear (thanks Sakari)
- "data-lanes" property reworked: it is now optional, and if it is not
present the driver should assume four-lane operation. For two-lane
operation (the only mode supported by the current driver) this property
must be present and set to <1 2>
imx219 sensor driver:
- "xclr-gpios" property renamed to "reset-gpios", the corresponding
struct gpio_desc field in the imx219 structure is renamed to reset_gpio
- in the driver probe() a test to check that the number of CSI-2 data lanes
is supported by the driver was added
- devm_clk_get() is now called with NULL as the 2nd argument, as there is
just single clock, and there is no need to use clock ID
- error messages are added when the driver fails to get regulators, to init
media entity pads, or to register sensor sub-device
Thanks,
Andrey
