Jonathan Cameron ea993a5193 staging:iio:adc:ad7152 bring more into line with abi.
Get rid of explicit writes to registers and conversion mode
control.

Couple of bits I'm unsure about.
* Do calibration modes self reset when done?  How do you tell they are
done?

* Should we poll the status register just to be sure we have a new conversion?

All done sans hardware.

Michael Hennerich cd400fc94d staging:iio:adc:ad7150: remove conversion mode handling.
The AD7150 family of devices power up in continues conversion mode.
We can stay in this mode, unless power consumption becomes a real issue.
Actually the event generation as well as the running average
relies on continues conversion mode, so we better stay there.

Jonathan Cameron ade7ef7ba3 staging:iio: Differential channel handling - use explicit flag rather than types.
Straight forward change in the core, but required some drivers to not use
the IIO_CHAN macro as that doesn't allow setting this bit (and is
going away anyway). Hence the churn.

Tested on max1363 with a couple of supported parts.

V2: differential bit in code got 7 bits and direction 1. Reversed that.
Issue spotted by Michael - thanks!

This costs us nothing in event storage (as we are carrying a 64 bit

Jonathan Cameron 32b5eecab0 staging:iio: Switch the channel masks to bitmaps so as to allow for more channels.
This is as light as possible on changes to current drivers.
Some drivers make assumptions that their masks fit in a single
long.  Given they were previously working this is clearly valid if
not tidy.

The max1363 is an example where there should be no such assumptions.

The scan mask will be dynamically assigned in register, so don't
use it before that.

In adis16260 I've moved it as I know this driver has userspace code.
Same for sca3000 where it is cost free due to hardware buffer.
Can do that for the others, but in theory userspace code should always
have been checking these and setting them appropriately anyway!
