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. Subject: [PATCH 0/4] input: TSC: ti_tscadc: TI Touchscreen driver updates [1]

Changes in v2: Dropped one patch send in the last version after receiving internal comments. I have merged the changes into existing patches. Also added a new patch to support suspend/resume feature. Fixed review comments by Matthias Kaehlcke.
