* | iio: dac: mcp4725: Add basic support for MCP4726Akinobu Mita2016-01-031-20/+67
|/ | | | | | | | | | | | | | | | | | | | | | MCP4726 is a single channel 12-bit DAC. We can support MCP4726 with a little changes to mcp4725 driver. In power-down mode, they have different selection of VOUT pull-down registers. MCP4726 also has features: - Output gain options: 1x, 2x - Voltage reference selection: VDD, VREF (Unbuffered or Buffered) But these are not supported in this change. (1x gain, VDD is selected) datasheet: http://ww1.microchip.com/downloads/en/DeviceDoc/22272C.pdf Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Cc: Jonathan Cameron <jic23@kernel.org> Cc: Hartmut Knaack <knaack.h@gmx.de> Cc: Lars-Peter Clausen <lars@metafoo.de> Cc: Peter Meerwald <pmeerw@pmeerw.net> Cc: linux-iio@vger.kernel.org Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio: delete non-required instances of include <linux/init.h>Paul Gortmaker2014-01-111-1/+0
| | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* iio:dac:mcp4725 drop specification of scan type as unused in this driver.Jonathan Cameron2013-12-171-1/+0
| | | | | | | | IIO_ST is going away as it is a pain to maintain so the simplest path with this driver is to not specify the unused scan type. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de>

* | iio: refactor info mask and ext_info attribute creation.Jonathan Cameron2013-09-151-1/+2
|/ | | | | | | | | | | | | | | | Introduce an enum to specify whether the attribute is separate or shared. Factor out the bitmap handling for loop into a separate function. Tidy up error handling and add a NULL assignment to squish a false positive warning from GCC. Change ext_info shared type from boolean to enum and update in all drivers.

* Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-4/+4
| | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
