This patch set is a followup of my previous series: iio: adc: at91 fixes
1-3) The first 3 patches are cleaning up the patform_data used for at91_adc.
4-5) Then touchscreen support for older ADCs is added, this allows to use that
for the sam9m10g45ek.
6) Following those modifications, the ma
The atmel_tsadcc driver is not used anymore, it has been replaced by at91_adc so
remove it.

The tsadcc node is useless as it doesn't refer to anything and the touchscreen

Hi Dimitry-
Here is a set of patches for atmel_mxt_ts that you've already signed-off. I've
rebased them against the most recent mainline and made some very minor changes

The configuration is stored in NVRAM on the maXTouch chip. When the device
is reset it reports a CRC of the stored configuration values. Therefore it
isn't necessary to send the configuration on each probe - we can check the
CRC matches and avoid a timeconsuming backup/reset cycle.

The delay before the chip can be accessed after reset varies between

* The mapping of the GPIO numbers into the T19 status byte varies between
different maXTouch chips. Some have up to 7 GPIOs. Allowing a keycode array
of up to 8 items is simpler and more generic. So replace #define with
configurable number of keys which also allows the removal of is_tp.
By implementing a frame counter, print out fewer debug messages (the
firmware may contain hundreds of frames).
