The sensor takes 3 supply rails - AVDD, DVDD, and DOVDD.
Add hooks into the regulator framework for each of these
regulators.

Previously regulators were enabled on probe and never again.
However, as regulators are disabled on power off. After a second power off
the regulator counter will underflow. Plus regulators are not required
for probing the sensor, but for streaming.
Fix this by enabling regulators on power on to balance regulator counter
properly.

The struct i2c_client pointer is used only to get driver data,
associated with a struct device or print messages on behalf.
Moreover, the very same pointer to a struct device is already
assigned by a regmap and can be retrieved from there.
No need to keep a duplicative pointer.

Still there are archs/platforms which do not support the common clk
framework. If such a platform is used in combination with the module
enabled the compiler will throw an error. Since the clock has stubs if
not selected we can drop it, so it is up to the arch/platform to select
the correct clock framework.

Despite being big, the changes here are trivial: they just change the

As noted in the headers for V4L2_SUBDEV_FL_HAS_EVENTS,
"controls can send events, thus drivers exposing controls
should set this flag".
This driver exposes controls, but didn't reflect that it
could generate events. Correct this, and add the default
event handler functions.

There's no reason why HBLANK has to be read-only as it
only changes the TIMING_HTS register in the sensor.
Remove the READ_ONLY flag, and add the relevant handling
for it.
The minimum value also varies based on whether continuous clock
mode is being used or not, so allow hblank_min to depend on
that.

Programming the sensor with TIMING_VTS (aka LPFR) was done
when triggered by a change in exposure or gain, but not
when V4L2_CID_VBLANK was changed. Dynamic frame rate
changes could therefore not be achieved.

by set_ctrl(V4L2_CID_VBLANK)

The configured vblank_min setting of 151 (meaning VTS of
720 + 151 = 871) is far higher than the setting that works on
the sensor, and there are no obvious restrictions stated in the

The calculations from pixel rate, width+hblank, and height+vblank
do not give the correct framerate - it's half the speed it should
be.
The datasheet lists the default for the TIMING_HTS registers (0x380c/d)
as being 0x2d8 (728) which is less than the width of the image, so
the units clearly can't be pixels.
If TIMING_HTS is considered to be units of 2-pixels, then the
resulting value of 0x5b0 (1456) makes all the calculations correct.
This driver is reporting an HBLANK value of 250, with an image width
of 1280, so TIMING_HTS is 1530 (0x5fa) pixels. However it was also
setting the register to 0x5fa, thereby not taking into account it
being units of 2-pixels.
Correct the register value to 0x2fd so that all the timing calculations
give the correct results.

https://patchwork.kernel.org/project/linux-media/patch/20220607134057.2427663-3-bryan.odonoghue@linaro.org/#24894500
Set up the .data parameter of of_device_id to pass a string which
we use to set the media entity name. Once done we can add in imx577 as a
compatible chips with the media names reflecting the directed compat string.
