Now that the three hardware peaces described in this file have been
translated in yaml in 3 dedicated files (MFD, touchscreen controller and
ADC) it is time to remove this text file.

AM654 SoCs has ADC IP which is similar to AM335x, but without the
touchscreen part. Add new compatible to handle AM654 SoCs. Also, it
seems that existing compatible strings used in the kernel DTs were never
documented. So, document them now.

Add optional DT properties to set open delay, sample delay and number
of averages per sample for each adc step. Open delay, sample delay
and averaging are some of the parameters that affect the sampling rate
and accuracy of the sample. Making these parameters configurable via
DT will help in balancing speed vs accuracy.

This patch reads charge delay from tsc DT node and writes to
REG_CHARGEDELAY register. If the charge delay is not specified in DT then
default value of 0x400(CHARGEDLY_OPENDLY) is used.

There was a spelling mistake on TSC/ADC binding where "coordinate" was
spelled as "coordiante".
We can't simply fix the error due to DT being an ABI, the approach taken
was to first use correct spelling and if that fails, fall back to
miss-spelled version.
It's unfortunate that has creeped into the tree.

This patch adds DT support to touch driver. It also provides a binding
document which is used by the MFD and IIO part of the device.
This patch also renames steps_to_configure to coordinate_readouts
because the original name misleads the purpose of the variable.
