* media: ov6650: Fix .get_fmt() V4L2_SUBDEV_FORMAT_TRY supportJanusz Krzysztofik2020-01-29
| | | | | | | | | | | | | | | | | | | | | [ Upstream commit 39034bb0c26b76a2c3abc54aa28c185f18b40c2f ] Commit da298c6d98d5 ("[media] v4l2: replace video op g_mbus_fmt by pad op get_fmt") converted a former ov6650_g_fmt() video operation callback to an ov6650_get_fmt() pad operation callback. However, the converted function disregards a format->which flag that pad operations should obey and always returns active frame format settings. That can be fixed by always responding to V4L2_SUBDEV_FORMAT_TRY with -EINVAL, or providing the response from a pad config argument, likely updated by a former user call to V4L2_SUBDEV_FORMAT_TRY .set_fmt(). Since implementation of the latter is trivial, go for it.

* media: ov6650: Fix some format attributes not under controlJanusz Krzysztofik2020-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 1c6a2b63095154bbf9e8f38d79487a728331bf65 ] User arguments passed to .get/set_fmt() pad operation callbacks may contain unsupported values. The driver takes control over frame size and pixel code as well as colorspace and field attributes but has never cared for remainig format attributes, i.e., ycbcr_enc, quantization and xfer_func, introduced by commit 11ff030c7365 ("[media] v4l2-mediabus: improve colorspace support"). Fix it. Set up a static v4l2_mbus_framefmt structure with attributes initialized to reasonable defaults and use it for updating content of user provided arguments. In case of V4L2_SUBDEV_FORMAT_ACTIVE, postpone frame size update, now performed from inside ov6650_s_fmt() helper, util the user argument is first updated in ov6650_set_fmt() with default frame format content. For V4L2_SUBDEV_FORMAT_TRY, don't copy all attributes to pad config, only those handled by the driver, then fill the response with the default frame format updated with resulting pad config format code and frame size.

* media: ov6650: Fix incorrect use of JPEG colorspaceJanusz Krzysztofik2020-01-29
| | | | | | | | | | | | | | | | [ Upstream commit 12500731895ef09afc5b66b86b76c0884fb9c7bf ] Since its initial submission, the driver selects V4L2_COLORSPACE_JPEG for supported formats other than V4L2_MBUS_FMT_SBGGR8_1X8. According to v4l2-compliance test program, V4L2_COLORSPACE_JPEG applies exclusively to V4L2_PIX_FMT_JPEG. Since the sensor does not support JPEG format, fix it to always select V4L2_COLORSPACE_SRGB.

* media: ov6650: Fix stored frame format not in sync with hardwareJanusz Krzysztofik2020-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 3143b459de4cdcce67b36827476c966e93c1cf01 ] The driver stores frame format settings supposed to be in line with hardware state in a device private structure. Since the driver initial submission, those settings are updated before they are actually applied on hardware. If an error occurs on device update, the stored settings my not reflect hardware state anymore and consecutive calls to .get_fmt() may return incorrect information. That in turn may affect ability of a bridge device to use correct DMA transfer settings if such incorrect informmation on active frame format returned by .get_fmt() is used. Assuming a failed device update means its state hasn't changed, update frame format related settings stored in the device private structure only after they are successfully applied so the stored values always reflect hardware state as closely as possible.

* media: ov6650: Fix sensor possibly not detected on probeJanusz Krzysztofik2019-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 933c1320847f5ed6b61a7d10f0a948aa98ccd7b0 upstream. After removal of clock_start() from before soc_camera_init_i2c() in soc_camera_probe() by commit 9aea470b399d ("[media] soc-camera: switch I2C subdevice drivers to use v4l2-clk") introduced in v3.11, the ov6650 driver could no longer probe the sensor successfully because its clock was no longer turned on in advance. The issue was initially worked around by adding that missing clock_start() equivalent to OMAP1 camera interface driver - the only user of this sensor - but a propoer fix should be rather implemented in the sensor driver code itself. Fix the issue by inserting a delay between the clock is turned on and the sensor I2C registers are read for the first time. Tested on Amstrad Delta with now out of tree but still locally maintained omap1_camera host driver.

| | | | | | | | | | | | | | | | | Release v2.6.30 removed the MT9M001_PCA9536_SWITCH and MT9V022_PCA9536_SWITCH Kconfig symbols, in commits 36034dc325ecab63c8cfb992fbf9a1a8e94738a2 ("V4L/DVB (11032): mt9m001: allow setting of bus width from board code") and e958e27adeade7fa085dd396a8a0dfaef7e338c1 ("V4L/DVB (11033): mt9v022: allow setting of bus width from board code"). These two commits removed all gpio related code from these two drivers. But they skipped removing their two selects of GPIO_PCA953X. Remove these now as they are outdated. Their dependencies can never evaluate to true anyhow.

* [media] mt9v022 driver: send valid HORIZONTAL_BLANKING values to mt9v024 soc ↵Andrei Andreyanau2013-03-21
| | | | | | | | | | | | | | | camera This patch fixes the issue that appears when mt9v024 camera is used with the mt9v022 soc camera driver. The minimum total row time is 690 columns (horizontal width + horizontal blanking). The minimum horizontal blanking is 61. Thus, when the window width is set below 627, horizontal blanking must be increased. For the mt9v024 camera the values above are correct and for the mt9v022 camera the correct values are in the existing kernel driver.

* [media] mt9m111: fix Oops - initialise context before dereferencingGuennadi Liakhovetski2013-03-21
| | | | | | | | | | | | A recent commit "[media] soc-camera: Push probe-time power management to drivers" causes an Oops during mt9m111 driver probing because its .ctx private data field is now dereferenced before it is initialised. Fix this by initialising the field earlier.

* [media] soc-camera: mt9m111: Fix auto-exposure controlBenoît Thébaudeau2013-03-21
| | | | | | | | | | | | | | | | Commit f9bd5843658e18a7097fc7258c60fb840109eaa8 changed V4L2_CID_EXPOSURE_AUTO from boolean to enum, and commit af8425c54beb3c32cbb503a379132b3975535289 changed the creation of this control into a menu for the mt9m111. However, mt9m111_set_autoexposure() is still interpreting the value set for this control as a boolean, which also conflicts with the default value of this control set to V4L2_EXPOSURE_AUTO (0). This patch makes mt9m111_set_autoexposure() interpret the value set for V4L2_CID_EXPOSURE_AUTO as defined by enum v4l2_exposure_auto_type.

* [media] mt9t112: mt9t111 format set up differs from mt9t112Guennadi Liakhovetski2013-02-13
| | | | | | | | | | | | | The original commit, adding the mt9t112 driver said, that mt9t111 and mt9t112 had identical register layouts. This however doesn't seem to be the case. At least pixel format selection in the mt9t111 datasheet is different from the driver implementation. So far only the default YUYV format has been verified to work with mt9t111. Limit the driver to only report one supported format with mt9t111 until more formats are implemented.
