iio:adc:ad7887 Fix channel reported endianness from cpu to big endian

2013-12-17T20:37:14+00:00

Note this also sets the endianness to big endian whereas it would
previously have defaulted to the cpu endian.  Hence technically
this is a bug fix on LE platforms.

First round of fixes for IIO in the 3.13 cycle.

The usual mixed bag of fixes.

* 3 cases where kconfig dependencies were missing.  We need to keep a closer
  eye on this in new drivers.

* hid_sensors was abusing the iio_dev->trigger pointer.  We had a round
  of clearing this out some time ago but this driver clearly slipped through.

* A misuse of the IIO_ST macro, in mcp3422, which we should really make a
  concertive effort to finish removing.

* Avoid a double free introduced by recent buffer reference counting in the
  one driver that (quite reasonably!) does things differently (am335x)

* A missing mutex_unlock in kxsd9 that means that driver has been non
  functional for some time and no one noticed (including me who for once
  actually has one of the supported devices).

* An incorrect assumption about the parameters of sign_extend32 in mcp3422.

So nothing controversial.  The only substantial patch is the hid_sensors
one and that is actually just adding a new pointer to the devices private
state then moving the code over to it.

tree-wide: use reinit_completion instead of INIT_COMPLETION

2013-11-15T00:32:21+00:00

Use this new function to make code more comprehensible, since we are
reinitialzing the completion, not initializing.

iio: adc: ti_am335x_adc: avoid double free of buffer.

2013-11-09T12:33:24+00:00

The driver is missing the iio_buffer_attach() call. As such it will attempt
to free the buffer twice on removal.

Introduced in commit 9e69c9 ("iio: Add reference counting for buffers").

iio: Fix sign extension table in mcp3422 driver

2013-11-05T22:45:25+00:00

the index argument to sign_extend32() gives the bit position (from 0)
to the sign bit

so e.g. if the measurement has 16-bit resolution, we need to pass 15;
a measurement of 0x8000 should be reported as -32768, not 32768

iio: at91: fix error return code in at91_adc_probe()

2013-11-02T12:07:54+00:00

Fix to return -ENODEV instead of 0 if non-TSMR adc don't
support, as done elsewhere in this function.

iio: adc: twl6030-gpadc: Remove redundant code

2013-10-24T13:45:09+00:00

The if check is redundant as the value obtained from
iio_device_register() is already in the required format.
Hence return the function directly.
