Hello, This patchset adds support for the DAC peripheral on Vybrid SoC. Patchset is based on top of shawn's for-next branch and has been tested on a Toradex Colibri VF50 module. @Jonathan I kept the IIO_SHARED_BY_DIR instead of using IIO_SHARED_BY_ALL since this gives "out_conversion_mode" allowing me to distinguish this in the ABI documentation, that this is explicitly for the DAC. Since 4.5-rc4 was released recently and assuming this makes it with this or next version, I assumed the target kernel version would be 4.6 and used that in ABI documentation. Feedbacks and comments most welcome. Changes since v2: 1. Add dependencies on OF and HAS_IOMEM in Kconfig 2. Fix ordering of disabling DAC and calling iio unregister Changes since v1: 1. Fix return type of vf610_dac_init function 2. Document conversion modes in sysfs-bus-iio-vf610 3. Remove "indexed" specification from iio_chan_spec 4. Use "return" directly from default case in switch 5. Remove DRIVER_NAME 6. Call vf610_dac_init before iio device registration 7. Define and use vf610_dac_exit function in remove and suspend v2 of the patchset http://www.spinics.net/lists/arm-kernel/msg482839.html v1 of the patchset: http://www.spinics.net/lists/arm-kernel/msg481190.html Thanks & Regards, Sanchayan Maity.
