Sensor tuning support is needed to determine the number of enabled
tx and rx electrodes for use in F54 functions.

The number of enabled electrodes is not identical to the total number
of electrodes as reported with F55:Query0 and F55:Query1. It has to be
calculated by analyzing F55:Ctrl1 (sensor receiver assignment) and
F55:Ctrl2 (sensor transmitter assignment).

Support for additional sensor tuning functions may be added later.

Ping ... any comments on this patch and on
https://patchwork.kernel.org/patch/9359061/ ?

Both patches now apply to mainline.

Thanks,
Guenter

Hi Guenter-

I've reviewed and tested (on S7300 and S7813) both these patches now
- you can add my sign-off.

However, on the S7813 firmware, F55 is on PDT page 3, and nothing
on page 2, so the default behaviour of the mainline driver means it is
not initialised.

So I think we need to revert this change in mainline:
https://patchwork.kernel.org/patch/3796971/

See below the PDT scan with it reverted and some debug added.

Christopher/Andrew: is there a better heuristic than scanning all 255
pages, given that some firmwares contain gaps?

cheers

Nick
