This patch set adds a MFD core driver which registers
touchscreen and ADC as its client drivers.
The existing touchscreen has been modified to work as
a MFD client driver and a new ADC driver has been added
in the IIO subsystem.
There are 8 analog input lines, which can be used as:
1. 8 general purpose ADC channels
2. 4 wire TS, with 4 general purpose ADC channels
3. 5 wire TS, with 3 general purpose ADC channels
This patch set has been tested on AM335x EVM.
These set of patches are based on top of Touchscreen patch
set submitted.
