You should split off the validation code into a separate function
(e.g. hwd_viif_l1_try_ag_mode) and add support for the try_ctrl op
where you call these 'try' functions.
The advantage is that applications can use VIDIOC_TRY_EXT_CTRLS to
check if the controls are valid, it's really where the checks should
be done.

NACK!
I thought those addresses in a struct were iffy. This is not supported, it
basically bypasses the whole control framework.
The way to do this is to create separate array controls for these tables.
And table_h_addr becomes a simple 0 or 1 value, indicating whether to use
the table set by that control. For small arrays it is also an option to
embed them in the control structure.
Are these l, h and m tables independent from one another? I.e. is it possible
to set l but not h and m? I suspect it is all or nothing, and in that case you
need only a single control to set all three tables (a two dimensional array).
Anyway, the same issue applies to all the controls were you pass addresses for
tables, that all needs to change.

EIO is definitely the wrong error code since that indicates a HW issue, and
that's not the case. Do you need to return an error here? Is there a reasonable
calibration status that you can return instead?
Presumably if it is not streaming, then that means 'uncalibrated', so perhaps
returning an 'uncalibrated' status here makes the more sense.
Also, I suspect you actually mean vb2_start_streaming_called() here. I assume
that the calibration step happens in start_streaming() which can be called later
than VIDIOC_STREAMON (which is the ioctl that sets 'is streaming' to true).

My question for these four controls is: are these really volatile controls?
A volatile control means that the hardware can change the registers at any
time without telling the CPU about it via an interrupt or some similar mechanism.
If there *is* such a mechanism, then it is not a volatile control, instead the
driver has to update the control value whenever the HW informs it about the
new value.
I can't tell, so that's why I ask here to double check.

This is not needed, it's not doing anything that the control framework already
does by default.

As mentioned above, you should add a try_ctrl callback as well to do the
validation. Note that if there is a try_ctrl callback, then set_ctrl doesn't
need to do the validation anymore since try_ctrl will be called before set_ctrl.

These strings appear as the name of the control and are supposed to be
