Subject: [PATCH v5 0/4] Support for TSC/ADC MFD driver

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 apply to linux-nxt branch and are based
on top of Touchscreen patch set submitted viz.
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.

Changes in v5:
	Merged suspend/resume part of code (present as separate patch)
	into the respective driver.

Patil, Rachna (4):
  input: TSC: ti_tscadc: Rename the existing touchscreen driver
  MFD: ti_tscadc: Add support for TI's TSC/ADC MFDevice
  input: TSC: ti_tsc: Convert TSC into a MFDevice
  IIO : ADC: tiadc: Add support of TI's ADC driver
