iio: dac: mcp4725: Add basic support for MCP4726
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>
