This fixes up the usb1401.c file to remove the usage of err() (which is gone), and the two-argument kmap_atomic() call, and the compat_ioctl pointer warning.

This was imported from the http://pub.ist.ac.at/~schloegl/src/ced1401/.git git repo at the request of Alois. The driver originally came from Cambridge Electronic Design Ltd and was authored by Greg P Smith and others, but Alois did the maintance work to get it into a semi-building state and pushed to get it into the main kernel tree here.

2012-09-17Merge tag 'iio-for-v3.7d' of ↵Greg Kroah-Hartman20-273/+1233
git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next IIO new drivers, features and rework for the 3.7 cycle, 4th set. Here we have 1) a set cleaning up and moving the ad7476 driver out of staging. Support for a number of additional parts is also added to that driver. 2) cleanups from various people for the in kernel interface code as that is getting more an more real use and hence people are picking up on minor issues that made it through review. Also a related useful set of utility functions to avoid duplicate code for converting IIO representations to other forms. 3) a new fractional type for our read_raw / write_raw functions. This allows avoiding loss of accuracy via the in kernel interfaces in some cases as well as being rather convenient for a lot of range -> scale conversions. 4) New AD5755 DAC driver. 5) Some Blackfin timer trigger improvements including hardware pulse control for device triggering. 6) Support for the ad7091r in the ad7476 driver.
2012-09-17iio: ad7476: Add support for the ad7091rLars-Peter Clausen1-4/+26
Add support for the ad7091r 12 bit ADC to the ad7476 driver. Although the ad7091r is not really related to any of the other devices supported by this driver, luckily for us there are not so many ways (which are not totally insane) how sampling a single channel ADC via SPI can be implemented and support for the ad7091r can be added to the driver with just a few adjustments. The ad7091r requires an external "conversion start" pulse to start a sample conversion. After the conversion has finished the result can be read via SPI. We depend on a IIO trigger to generate this signal, as a result only sampling in buffered mode and not in manual mode is available.

2012-09-17staging:iio:trigger:bfintmr Add output supportLars-Peter Clausen2-16/+80
Some converters require an external signal to start the conversion. This patch adds support to the bfintmr trigger driver to generate such a signal. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-09-17staging:iio:trigger:bfintmr: Only enable timer when necessaryLars-Peter Clausen1-3/+24
This patch hooks up the set_trigger_state callback for the blackfin timer trigger driver and only enables the timer when a trigger consumer requests it to be enabled. There really is no reason to keep the timer running and generate interrupts if nobody is listening to them. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-09-17staging:iio:trigger:bfintmr: Avoid divide by zeroLars-Peter Clausen1-2/+8
If the timer frequency has not been configured yet get_gptimer_period() will return 0. Handle this case instead of blindly dividing by the returned value. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-09-17staging:iio:hwmon bridge: Use iio_read_channel_processedLars-Peter Clausen1-28/+5
Use the iio_read_channel_processed function to read the sample value in the proper unit instead of using iio_read_channel_raw and iio_read_channel_scale and doing the unit conversion manually. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-09-17iio:inkern: Add function to read the processed valueLars-Peter Clausen3-9/+164
Add a function to read a processed value from a channel. The function will first attempt to read the IIO_CHAN_INFO_PROCESSED attribute. If that fails it will read the IIO_CHAN_INFO_RAW attribute and convert the result from a raw value to a processed value. The patch also introduces a function to convert raw value to a processed value and exports it, in case a user needs or wants to do the conversion by itself. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2012-09-17iio: consumer.h: Fix kernel doc incosistencyLars-Peter Clausen1-2/+2
For the iio_read_channel_raw and iio_read_channel_scale the kerneldoc comment refers to an argument called "channel", while the argument is called "chan" in the function signature. This leads to the following warnings from kerneldoc: Warning(include/linux/iio/consumer.h:71): No description found for parameter 'chan' Warning(include/linux/iio/consumer.h:71): Excess function parameter 'channel' description in 'iio_read_channel_raw' Warning(include/linux/iio/consumer.h:109): No description found for parameter 'chan' Warning(include/linux/iio/consumer.h:109): Excess function parameter 'channel' description in 'iio_read_channel_scale' This patch fixes the warnings by naming them consistently.

2012-09-17iio:dac: Add ad5755 driverLars-Peter Clausen4-0/+765
This patch adds support for the AD5755, AD5755-1, AD5757, AD5735, AD5737 16 and 14 bit quad-channel DACs. The AD5757/AD5737 only have current outputs, but for the AD5755/AD5757 each of the outputs can be configured to either be a voltage or a current output. We only allow to configure this at device probe time since usually this needs to match the external circuitry and should not be changed on the fly. A few trivial formatting changes on merge.

2012-09-17iio: inkern: add error case in iio_channel_get()Kim, Milo1-1/+10
The datasheet name is defined in the IIO driver. On the other hand, the adc_channel_label is configured in the platform side. If the datasheet name is not matched with any adc_channel_label, the iio_channel_get() should be returned as error for preventing invalid channel data access. This can be handled either way. (a) checking null data when using it : in the xxx_read_raw() or (b) error returns when the channel is requested : this patch The IIO consumer can't use the channel with invalid channel spec. Therefore case (b) is more reasonable. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
