Should be upstream commit 42765b80f8c6 The sensor supports H & V flips, so add the relevant hooks for V4L2_CID_HFLIP and V4L2_CID_VFLIP to configure them. Note that the Bayer order is maintained as the readout area shifts by 1 pixel in the appropriate direction (note the comment about the top margin being 8 pixels whilst the bottom margin is 9). The V4L2_SEL_TGT_CROP region is therefore adjusted appropriately.

Should be upstream commit 97792a11021b The driver exposed V4L2_CID_VBLANK as a read only control to allow for exposure calculations and determination of the frame rate. Convert to a read/write control so that the frame rate can be controlled.

Should be upstream commit 4381df0c756f The datasheet lists the link frequency changes between 1080p and 720p modes. This is correct that the link frequency changes as measured on an oscilloscope. Link frequency is not necessarily the same as pixel rate. The datasheet gives standard configurations for 1080p and 720p modes at a number of frame rates. Looking at the 1080p mode it gives: HMAX = 0x898 = 2200 VMAX = 0x465 = 1125 2200 * 1125 * 60fps = 148.5MPix/s Looking at the 720p mode it gives: HMAX = 0xce4 = 3300 VMAX = 0x2ee = 750 3300 * 750 * 60fps = 148.5Mpix/s This driver currently scales the pixel rate proportionally to the link frequency, however the above shows that this is not the correct thing to do, and currently all frame rate and exposure calculations give incorrect results. Correctly report the pixel rate as being 148.5MPix/s under any mode.

The name of the input clock, "xclk", is wrong as the hardware manual names it INCK. As the device has a single clock, the name could be omitted, but that would require a corresponding change to the driver and is thus a candidate for further patches.

Upstream commit 02852c01 Initializing the subdev before runtime PM means that no subdev initialization can interact with the runtime PM framework. This can be problematic when modifying controls, as the .s_ctrl() handler commonly calls pm_runtime_get_if_in_use(). These code paths are not trivial, making the driver fragile and possibly causing subtle bugs. To make the subdev initialization more robust, initialize runtime PM first.

Upstream commit 10591fe6 The imx290_pixfmt structure contains information about formats, currently limited to the bpp value. Extend it with the register settings for each format, and rename it to imx290_format_info to make its purpose clearer. Add a function named imx290_format_info() to look up format info for a media bus code, and use it through the code. This allows dropping the imx290 bpp field as the value is now looked up dynamically. The error handling in imx290_setup_format() can also be dropped, as the format is guaranteed by imx290_set_fmt() to be valid.
