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 v1 [1]:
dt-bindings:
- license updated to (GPL-2.0-only OR BSD-2-Clause)
- non-standard 'camera-clk' property has got type, description, properties,
and required
- 'clock-lanes', 'data-lanes', and 'clock-noncontinuous' moved to the correct
node, the syntax has been fixed
- 'port' added to required properties
- minor corrections to some other property descriptions
imx219 sensor driver:
- fixed width variables replaced with '[unsigned] int' where appropriate
- excessive comments dropped
- imx219_get_format_code() returns 'codes[...]', and doesn't use an extra
internal variable any more
- initializing 'ret' to 0 in the beginning of imx219_set_ctrl() dropped
- uses IMX219_XCLK_FREQ macro instead of hardcoded number
- IMX219_REG_ORIENTATION is dropped from the mode_*x*_regs[] tables as it is
written by the control handler
- imx219_stop_streaming() return value changed to void
- calling imx219_power_on() moved from imx219_identify_module() to
imx219_probe(), and calling imx219_power_off() in the probe() error path
has been added. This simplifies imx219_identify_module(), and ensures
that the sensor is powered off after probe() and until streaming is
started
- comment referring to "xclr" pin changed to call it "enable pin" vs "power
down pin" to better match the "OUT_HIGH" pin configuration
