[ Upstream commit 3cdc776e0a5f1784c3ae5d3371b64215c228bf1f ] It was reported to me that the imx219 didn't work on one of our development kits partly because the access sequence is incorrect. The datasheet I could find [1] for this camera has the access sequence: Seq. No. Address (Hex) data 1 30EB 05 2 30EB 0C 3 300A FF 4 300B FF 5 30EB 05 6 30EB 09 but the driver swaps the first two elements. Laurent pointed out on IRC that the original code used the correct sequence for 1920x1080 but the current sequence for 3280x2464 and 1640x1232. During refactoring of the init sequence the current order was used for all formats. Switch to using the documented sequence.

2024-08-03media: i2c: Fix imx412 exposure controlBryan O'Donoghue1-5/+4
[ Upstream commit a1956bf53a2774014ee1768b484af2c38c633a25 ] Currently we have the following algorithm to calculate what value should be written to the exposure control of imx412. lpfr = imx412->vblank + imx412->cur_mode->height; shutter = lpfr - exposure; The 'shutter' value is given to IMX412_REG_EXPOSURE_CIT however, the above algorithm will result in the value given to IMX412_REG_EXPOSURE_CIT decreasing as the requested exposure value from user-space goes up. e.g. [ 2255.713989] imx412 20-001a: Received exp 1608, analog gain 0 [ 2255.714002] imx412 20-001a: Set exp 1608, analog gain 0, shutter 1938, lpfr 3546 [ 2256.302770] imx412 20-001a: Received exp 2586, analog gain 100 [ 2256.302800] imx412 20-001a: Set exp 2586, analog gain 100, shutter 960, lpfr 3546 [ 2256.753755] imx412 20-001a: Received exp 3524, analog gain 110 [ 2256.753772] imx412 20-001a: Set exp 3524, analog gain 110, shutter 22, lpfr 3546 This behaviour results in the image having less exposure as the requested exposure value from user-space increases. Other sensor drivers such as ov5675, imx218, hid556 and others take the requested exposure value and use the value directly. Take the example of the above cited sensor drivers and directly apply the requested exposure value from user-space. The 'lpfr' variable still functions as before but the 'shutter' variable can be dispensed with as a result. Once done a similar run of the test application requesting higher exposure looks like this, with 'exp' written directly to the sensor. [ 133.207884] imx412 20-001a: Received exp 1608, analog gain 0 [ 133.207899] imx412 20-001a: Set exp 1608, analog gain 0, lpfr 3546 [ 133.905309] imx412 20-001a: Received exp 2844, analog gain 100 [ 133.905344] imx412 20-001a: Set exp 2844, analog gain 100, lpfr 3546 [ 134.241705] imx412 20-001a: Received exp 3524, analog gain 110 [ 134.241775] imx412 20-001a: Set exp 3524, analog gain 110, lpfr 3546 The result is then setting the sensor exposure to lower values results in darker, less exposure images and vice versa with higher exposure values.

99a741aa7a2d ("i2c: mux: gpio: remove support for class-based device instantiation") removed the last call to i2c_mux_add_adapter() with a non-null class argument. Therefore the class argument can be removed. Note: Class-based device instantiation is a legacy mechanism which shouldn't be used in new code, so we can rule out that this argument may be needed again in the future.

On some ACPI platforms, such as Chromebooks the ACPI methods to change the power-state (_PS0 and _PS3) fully take care of powering on/off the sensor. On other ACPI platforms, such as e.g. various HP models with IPU6 + hi556 sensor, the sensor driver must control the sensor's clock itself. Add support for having the driver control an optional clock.

There is no reason to send OV2680_END_MARGIN extra columns on top of the mode width and the same for sending extra lines over the mode height. This sending of extra lines/columns was inherited from the atomisp ov2680 driver, it is unclear why this was done and this complicates adding V4L2_CID_VBLANK support, so remove it.

Since commit 63b0cd30b78e ("media: ov2680: Add bus-cfg / endpoint property verification") the ov2680 driver no longer probes when the 'data-lanes' property is absent. The OV2680 sensor has only one data lane, so there is no need for describing it the devicetree. Remove the unnecessary data-lanes property check.

The sensor gain (both analog and digital) are controlled by a single gain value where: - 0dB to 30dB correspond to analog gain - 30.3dB to 72dB correspond to digital gain (with 0.3dB step) Hence, limit the analogue gain value to 100. For digital gain, support can be added later if needed.

The imx335 reports a recommended pixel area of - 2592x1944. The driver supported mode however limits it to height=1940. Fix the height discrepency by correctly the value of height (with updates to vblank and mode registers). The IMX335_REG_HTRIMMING should also be corrected to the start offset(i.e. 48) instead of chosing a abritrary crop start of 384.
