* staging:iio: Add support for multiple buffersJonathan Cameron2012-11-10
| | | | | | | | | Route all buffer writes through the demux. Addition or removal of a buffer results in tear down and setup of all the buffers for a given device. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Tested-by: srinivas pandruvada <srinivas.pandruvada@intel.com>
* staging:iio: Move the ad7887 driver out of stagingLars-Peter Clausen2012-11-05
| | | | | | | | The driver does not expose any custom API to userspace and none of the standard static code checker tools report any issues, so move it out of staging. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* staging:iio:ad7887: Use passed in chan spec in ad7887_read_rawLars-Peter Clausen2012-11-05
| | | | | | | | | | Use the passed in chan spec in ad7887_read_raw instead of alawys using the first chan spec entry from the chip info data. Since all channels have the same shift and realbits from a functional point of view it does not matter which chan spec is used, but the patch makes the a bit more clear.

* staging:iio:ad7887: Allow to use internal ref in two channel modeLars-Peter Clausen2012-11-05
| | | | | | | | | | | While it is not recommended to use the internal reference in two channel mode in order to obtain optimal performance it is still possible to use it. While we are at it also get rid of the duplicate tx_cmd_buf entries. There are only two unique entries. One for channel 1 and one for channel 2.

* staging:iio:ad7887: Squash everything into one fileLars-Peter Clausen2012-11-05
| | | | | | | | | | | The recent cleanups have decimated the drivers code size by quite a bit. It is only a few hundred lines in total now and we also always build buffer support, so there really is no need to spread the driver out over multiple files. Putting everything into one file also allows to reduce the code size a bit more by removing a few lines of boilerplate code.

* staging:iio:ad7887: Rework regulator handlingLars-Peter Clausen2012-11-05
| | | | | | | | | | | Rework the regulator handling of the ad7887 driver to match more closely what we do for other drivers. Only request the regulator if a external reference is used, but treat it as an error if requesting the regulator fails. Also remove the possibility to specify the reference voltage via platform data and always use the regulator for this.

* staging:iio:ad7887: Preallocate sample bufferLars-Peter Clausen2012-11-05
| | | | | | | | | We know that the sample buffer will at most need to hold two 16 bit samples and the 64 bit aligned 64 bit timestamp. Preallocate a buffer large enough to hold this instead of allocating and freeing it each time a sample is read.

* staging:iio:adis16400: Set the PROD_ID flag for the adis16334Lars-Peter Clausen2012-11-04
| | | | | | | The adis16334 has the PROD_ID register so set the PROD_ID flag in its chip info. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* staging:iio:adis16400: Remove now duplicated chip_table entryLars-Peter Clausen2012-11-04
| | | | | | | | | | The ADIS1360 and ADIS13605 are very similar and do have the same software interface. The only difference is the contents of the PROD_ID register. Since we now read the product id from the device name instead of the chip_info struct we can use the same chip_table entry for both the ADIS1360 and ADIS13605.

* staging:iio:adis16400: Fix product id checkLars-Peter Clausen2012-11-04
| | | | | | | | | | | | | | | | | The product id check currently ANDs the read id with 0xF000 and compares the result to the product id from the chip info. Since none of the product ids in the chip info table end in 0x000 the check will always fail. Furthermore it is also wrong, the product id in the PROD_ID register will always match the part number of the device. Some of the ADIS16XXX devices are identical from a software point of view with the product id register having a different content. If we keep the current scheme of storing the product id in the chip info table this would require us to have multiple almost identical chip info table entries. So instead this patch changes the code to parse the product id from the device name. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* staging:iio:adis16400: Fix adis16334 sampling frequency controlLars-Peter Clausen2012-11-04
| | | | | | | | | | | | | | | Setting the sampling frequency for the adis16334 differs from the other devices. This patch introduces two new callback functions to the adis16400 chip_info struct which are used to specify how to read and write the current sample rate. The patch also introduces the proper implementations for these callbacks for the adis16334. Related to this is that the adis16334 has no slow mode and so we do not limit the SPI clock rate to 300kHz during initialization. The patch adds a new flag for devices which do have a slow mode.

* staging: comedi: adl_pci9118: support auto-attachmentIan Abbott2012-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | Support auto-attachment of supported PCI devices by adding the `auto_attach()` hook (`pci9118_auto_attach()`) to the `struct comedi_driver`. This is called via `comedi_pci_auto_attach()` at PCI probe time. Previously, the driver's call to `comedi_pci_auto_config()` would fall back to the old method of auto-attaching devices and would fail because it couldn't find a board name matching the driver name. The new method doesn't care about that. There are still a few problems. All the boards supported by this driver have the same PCI vendor and device ID, so it will just pick the first supported board type, "pci9118dg". (Other supported board types have different AI ranges or different AI speeds, but are otherwise the same.) Also, manual attachment of devices allows several optional features to be configured, such as use of an external multiplexord, specified sample&hold delays and options to ignore certain hardware errors. These will all be set to defaults for auto-attached devices. A future version of the driver may address these issues via configurable device attributes.

* staging: comedi: adl_pci9118: split pci9118_attach()Ian Abbott2012-11-02
| | | | | | | | | | | | | | | | | | Split most of the functionality of the attach routine `pci9118_attach()` into a new function `pci9118_common_attach()` that can be called when auto-attachment of devices is supported. Move the enabling of the PCI device and its i/o regions into this function. Do the requesting of the interrupt near the end of the function so it doesn't get enabled before the device is ready. Note that auto-attachment of PCI devices is currently broken in this driver because the list of board names referred to by the `struct comedi_driver` does not contain a "wildcard" entry matching the comedi driver name. This won't be a problem once support for the `auto_attach()` method is added. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
