Add support for Microchip MCP48F(E/V)B(0/1/2)1,
MCP48F(E/V)B(0/1/2)2, MCP48F(E/V)B(0/1/2)4 and
MCP48F(E/V)B(0/1/2)8 series of buffered voltage output Digital-to-Analog
converters with SPI Interface on MCP47F(E/V)B(0/1/2)(1/2/4/8).
This driver covers the following part numbers:
- With I2C Interface:
- With nonvolatile memory:
- MCP47FEB01, MCP47FEB02, MCP47FEB04, MCP47FEB08,
MCP47FEB11, MCP47FEB12, MCP47FEB14, MCP47FEB18,
MCP47FEB21, MCP47FEB22, MCP47FEB24, MCP47FEB28
- With volatile memory:
- MCP47FVB01, MCP47FVB02, MCP47FVB04, MCP47FVB08,
MCP47FVB11, MCP47FVB12, MCP47FVB14, MCP47FVB18,
MCP47FVB21, MCP47FVB22, MCP47FVB24, MCP47FVB28
- With SPI Interface:
- With nonvolatile memory:
- MCP48FEB01, MCP48FEB02, MCP48FEB04, MCP48FEB08,
MCP48FEB11, MCP48FEB12, MCP48FEB14, MCP48FEB18,
MCP48FEB21, MCP48FEB22, MCP48FEB24, MCP48FEB28
- With volatile memory:
- MCP48FVB01, MCP48FVB02, MCP48FVB04, MCP48FVB08,
MCP48FVB11, MCP48FVB12, MCP48FVB14, MCP48FVB18,
MCP48FVB21, MCP48FVB22, MCP48FVB24, MCP48FVB28

The families support up to 8 output channels. The devices can be 8-bit,
10-bit and 12-bit resolution.
