2016-02-08iio:ad5064: Add AD5625/AD5627/AD5645/AD5647/AD4665/AD5657 supportLars-Peter Clausen2-11/+188
The AD5625/AD5645/AD5665 are a family of 4 channel DACs with 12-bit, 14-bit and 16-bit precision respectively. The devices come in 3 flavors in terms of built-in reference, either no built-in reference, built-in 1.25V reference or built-in 2.5V reference. The AD5627/AD5647/AD5667 are similar to the AD5625/AD5645/AD5665 except that they have 2 instead of 4 channels. While these new devices are mostly register map compatible with the existing devices support by the driver some offsets and register addresses have been shuffled around. To accommodate this introduce a new register map layout. For the lack of a better name we will just call it version 2.

2016-02-08iio:ad5064: Use a enum for the register map layout typeLars-Peter Clausen1-13/+41
Currently the ad5064 only supports two different register map variations and this is represented by a bool. This patch changes since to a enum so we can support more variations in the future. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2016-02-08iio:ad5064: Add support for ltc2617 and similar devicesMarc Andre1-1/+111
The Linear Technology LTC2606, LTC2607, LTC2609, LTC2616, LTC2617, LTC2619, LTC2626, LTC2627 and LTC2629 devices are very similar to the AD5064 device. This patch adds support for those devices.

2016-02-08iio:ad5064: Structural changes to support LTC2617Marc Andre1-29/+38
This patch makes minor structural changes to support specifics for LTC2617 DAC. This DAC requires different handling of the power down modes. The configuration to actually support the DAC will be submitted in a secondary patch. Adjust the DECLARE_AD5064_CHANNELS() macro to accept a new ext_info parameter. This allows to use different power down modes per DAC. (e.g. DAC only support 90kohm to ground) Add the chip_info parameter "powerdown_ltc". This parameter is used in the ad5064_sync_powerdown_mode() function to handle the power down command for LTC diffently. For those devices the power down command must be addressed to the channel.
