2011-09-06staging:iio:imu:adis16400 cleanupsJonathan Cameron
a) remove irq is gpio requirement - No reason this needs to be true. b) use actual part name in info message rather than adis16400 in all cases. c) scrap use of IIO_CHAN to simplify move out of staging.

2011-09-06staging:iio:adc:ad7291 bring into line with current abi + chan_spec conversion.Jonathan Cameron
Also add some locking. Some major changes to how this driver works. For voltage channels it is currently either in single read mode or in a monitor mode (events only). Could be much cleverer and allow reading of any channels that happend to be monitored, but haven't done that yet.

2011-09-06staging:iio:adc:ad7152: Miscellaneous fixes and touch-upMichael Hennerich
Remove unused define. Introduce cached SETUP variables. Wait until calibration finished. (Device returns to idle state) IIO_CHAN_INFO_CALIBSCALE_SEPARATE use proper scales. (range 1.0 to 1.99999) i2c_smbus word transactions expect low byte first, therefore swap bytes. CAPDIFF is bit in SETUP not CFG.

2011-09-06staging:iio:adc:ad7152 bring more into line with abi.Jonathan Cameron
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.

2011-09-06staging:iio:adc:ad7150: remove conversion mode handling.Michael Hennerich
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.

2011-09-06staging:iio: Differential channel handling - use explicit flag rather than ↵Jonathan Cameron
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!

2011-09-06staging:iio:naming in the EV_BIT macro fix.Jonathan Cameron
Should always have been IIO_EV_DIR_MAX as that's what it actually controls. Also reduced the number to 4 as not yet seen a case needing more and this is not userspace visible anyway. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-09-06staging:iio:events - new 64 bit code structure and push out drivers.Jonathan Cameron
This costs us nothing in event storage (as we are carrying a 64 bit timestamp in the structure) and gives us lots more room to play with. Also allows for more channels which some parts need.

2011-09-06staging:iio: Switch the channel masks to bitmaps so as to allow for more ↵Jonathan Cameron
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.

2011-09-06staging:iio:various move default scan mask setting after ring register or removeJonathan Cameron
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!
