[PATCH 0/4] iio: input: ti_am335x_adc: Add continuous sampling support round 4

[Zubair Lutfullah <zubair.lutfullah@gmail.com>]

Note: These apply to the fixes-togreg branch in IIO because of
a fix on the adc side in there.

The first few are for input which tweak the TSC driver to
allow ADC in continuous mode with irqs to work nicely together.

The last one is for iio which adds continuous mode to the adc side.

Received feedback on previous series.
1. What if IRQs occur together? 
This is handled now. Even if both assert.
They both work.

2. IIO error handling wrong. 
Fixed now.

3. Headers wierd in IIO. 
Fixed.

Apart from that, found a few bugs in continuous mode
here and there. And squashed them into the same patch.

Thanks
