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] [1] http://www.spinics.net/lists/linux-input/msg22107.html 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. Changes in v3: Addressed review comments by Jonathan Cameron. Improved ADC driver with more readable labels, spaces and comments. Changes in v4: Renamed the drivers from ti_xxx to ti_am335x_xxx. For consistency with other drivers renamed idev to indio_dev in IIO ADC driver. Replaced suspend/resume callbacks with dev_pm_ops.
