The set_fmt() in subdev pad ops, the s_ctrl() for subdev control handler, and the s_frame_interval() in subdev video ops could be called when the device is under power saving mode. These callbacks for ov772x driver cause updating H/W registers that will fail under power saving mode. This avoids it by not apply any changes to H/W if the device is not powered up. Instead the changes will be restored right after power-up. Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by:

The ov772x driver provides three V4L2 controls and the current value of each control is saved as a variable in the private data structure. We don't need to keep track of the current value by ourself, if we use v4l2_ctrl returned from v4l2_ctrl_new_std() instead. This is a preparatory change to avoid accessing registers under power saving mode. This simplifies s_ctrl() by making it just return without saving the current control value in private area when it is called under power saving mode.

Depending on the v4l2 driver, calling s_power() could be nested. So the actual transitions between power saving mode and normal operation mode should only happen at the first power on and the last power off. This adds an s_power() nesting counter and updates the power state if the counter is modified from 0 to != 0 or from != 0 to 0.

The ov772x driver currently only supports legacy platform data probe. This change enables device tree probing. Note that the platform data probe can select auto or manual edge control mode, but the device tree probling can only select auto edge control mode for now.

Currently the ov772x driver obtains a clock with a specific consumer ID. As there's a single clock for this driver, we could omit clock-names property in device tree by passing NULL as a consumer ID to clk_get().

The ov772x driver uses "rstb-gpios" and "pwdn-gpios" for reset and powerdown pins. However, using generic names for these gpios is preferred. ("reset-gpios" and "powerdown-gpios" respectively) There is only one mainline user for these gpios, so rename to generic names.

The ov772x driver only works when the i2c controller have I2C_FUNC_PROTOCOL_MANGLING. However, many i2c controller drivers don't support it. The reason that the ov772x requires I2C_FUNC_PROTOCOL_MANGLING is that it doesn't support repeated starts. This changes the reading ov772x register method so that it doesn't require I2C_FUNC_PROTOCOL_MANGLING by calling two separated i2c messages.

Add HFLIP/VFLIP controls support by setting registers REG21/REG20. Useless values in hardcoded mode sequences are removed and remaining binning values are now set after mode sequence being set. Note that due to BSI (Back Side Illuminated) technology, image capture is physically mirrored, mirror logic is so inversed in REG21 register to cancel this effect. Signed-off-by:

Sensors are occasionally mounted upside down to systems such as mobile phones or tablets. In order to use such a sensor without having to turn every image upside down, most camera sensors support reversing the readout order by setting both horizontal and vertical flipping. This patch documents the "rotation" property for camera sensors, mirroring what is defined for displays in Documentation/devicetree/bindings/display/panel/panel.txt . Signed-off-by:

The __NEED_MEDIA_LEGACY_API define is 1) ugly and 2) dangerous since it is all too easy for drivers to define it to get hold of legacy defines. Instead just define what we need in media-device.c which is the only place where we need the legacy define (MEDIA_ENT_T_DEVNODE_UNKNOWN). Signed-off-by:

This reverts commit 0866df8d. The v4l uAPI documentation [0] makes clear that in the case of interlaced video (i.e: field is V4L2_FIELD_ALTERNATE) the height refers to the number of lines in the field and not the number of lines in the full frame (which is twice the field height for interlaced formats). So the original height calculation was correct, and it shouldn't had been changed by the mentioned commit.

Currently, rga_buf_start_streaming() is expecting pm_runtime_get_sync to return zero on success, which is wrong. As per the documentation, pm_runtime_get_sync increments the device's usage counter and return its result. This means it will typically return a positive integer on success and a negative error code. Therefore, rockchip-rga driver is currently unusable failing to start_streaming in most cases. Fix it and while here, cleanup the buffer return-to-core logic.

When checking a format for validity, the resolution is reset to 1280x720 whenever the pixel format is not supported. This behavior can mislead user-space into believing that this is the only resolution supported, and looks strange considering that if we try/set the same format with just the pixel format changed to a valid one, the call will this time succeed without altering the resolution. Resolution is managed independently of the pixel format, so remove this reset. Signed-off-by:
