Currently 2-bytes and 3-bytes registers are read one byte at a time, doing the needed shift & mask each time. Replace all of this code by a unique helper function that calls regmap_bulk_read(), which has two advantages: - reads all the bytes in a unique I2C transaction - simplifies code to read multibyte registers Signed-off-by:

A mix of "mode", "format" and "frmfmt" is used to refer to the sensor readout mode. Use the term "mode" for all of them. Now "format" is only used in the V4L2 meaning. Signed-off-by:

Forcibly setting the subdev name to DRIVER_NAME (i.e. "IMX274") makes it non-unique and less informative. Let the driver use the default name from i2c, e.g. "IMX274 2-001a". Signed-off-by:

Rearrange the imx274_start_<N> register tables to better match the datasheet and slightly simplify code: - collapes tables 1 and 2, they are applied one after each other and together they implement the fixed part 1 of the startup procedure in the datasheet - while there, cleanup comments - rename tables 3 and 4 -> 2 and 3, coherently with the datasheet Signed-off-by:

The "mode" has been renamed to "binning" in commit 39dd23dc ("media: imx274: add cropping support via SELECTION API"), but this define has not been updated. Signed-off-by:

Add the DT binding documentation for dw9714 and dw9807-vcm to the MAINTAINERS file. The dw9807-vcm binding documentation file is renamed to match the dw9807's VCM bit's compatible string. Signed-off-by:

The UDS is currently restricted based on a partition size of 256 pixels. Document the actual restrictions, but don't increase the implementation. The extended partition algorithm may later choose to utilise a larger partition size to support overlapping partitions which will improve the quality of the output images. Signed-off-by:

The SRU is currently restricted to 256 pixels as part of the current partition algorithm. Document that the actual capability of this component is 288 pixels, but don't increase the implementation. The extended partition algorithm may later choose to utilise a larger input to support overlapping partitions which will improve the quality of the output images. Signed-off-by:

The style of this driver uses periods at the end of sentences in comments, but it is applied inconsitently. Update a selection of comments which were discovered to be missing their period. Also fix the spelling of one usage of 'instantiate' Signed-off-by:

The VSP1 has a minimum width and height of a single pixel, with the exception of pixel formats with sub-sampling. Remove the artificial minimum width and minimum height limitation, and instead clamp the minimum dimensions based upon the sub-sampling parameter of that dimension. Signed-off-by:

YCbCr planar formats can have different pitch values for the luma and chroma planes. This isn't taken into account in the driver. Fix it. Based on a BSP patch from Koji Matsuoka <koji.matsuoka.xm@renesas.com>.

The LIF module has a data buffer to accommodate clock rate differences between the DU and the VSP. Several programmable threshold values control DU start of frame notification by the VSP and VSP clock stop/resume. The R-Car Gen2 and Gen3 datasheets recommend values for the different SoCs. Update the driver to use the recommended values for optimal operation. Based on a BSP patch from Koji Matsuoka <koji.matsuoka.xm@renesas.com>, with Gen2 and V3H/V3M updates. Signed-off-by:

All source files of the vsp1 driver are licensed under the GPLv2+ except for vsp1_regs.h which is licensed under GPLv2. This is caused by a bad copy&paste that dates back from the initial version of the driver. Fix it. Acked-by:

When irq is used, the lock is set via IRQ code. When it isn't, the driver just assumes it is always locked. Instead, read the lock status from the status register. Signed-off-by: -

Since commit 9a4c7e68f7e0 ("media: tvp5150: convert register access to regmap")' the driver supports regmap. Now we can drop the handmade bit update sequence and move to the regmap provided helpers. Signed-off-by: -

Regmap provides built in debugging, caching and provides dedicated accessors for bit manipulations in registers, which make the following changes a lot simpler. Signed-off-by:

The function only consists of a single switch case block without a default case. Unsupported control requests are indicated by the -EINVAL return code trough the last return statement at the end of the function. So exiting just the switch case block returns the -EINVAL error code but the hue control is supported and a zero should be returned instead. Replace the break by a 'return 0' to fix this behaviour.

Now that all drivers are using pad signal types, we can get rid of the global static definition, as routes are stablished using the pad signal type. The tuner and IF-PLL pads are now used only by the tuner core, so move the definitions to be there. Acked-by:
