Hello,
This series first adds support for parts missing from mcp4531 driver
(MCP454x, MCP456x, MCP464x and MCP466x). It then introduces the necessary
device tree binding to perform DT boot. Finally it fixes a typo in the
Kconfig.
Tested with MCP4561-103 and MCP4561-503 (DT boot).
Best regards,
Florian
---
Since v1:
- Applied Acks
- Moved the binding to i2c/trivial-devices.txt
- Fixed data pointer handling in struct of_device_id
- Renamed struct of_device_id to mcp4531_of_match
- New patch to fix typo in Kconfig

The main difference with currently supported parts (MCP453x and alike) is the addition of a non-volatile memory in order to recall the wiper setting at power-on. This feature is currently not supported and only the volatile memory is used to set the wiper.

I'd be happier with either ignoring the 80 char rule, or skipping the leading tab. I.e. { .compatible = "microchip,mcp4531-502", .data = &mcp4531_cfg[MCP453x_502] }, { .compatible = "microchip,mcp4531-103", .data = &mcp4531_cfg[MCP453x_103] }, { .compatible = "microchip,mcp4531-503", .data = &mcp4531_cfg[MCP453x_503] }, ... or { .compatible = "microchip,mcp4531-502", .data = &mcp4531_cfg[MCP453x_502] }, { .compatible = "microchip,mcp4531-103", .data = &mcp4531_cfg[MCP453x_103] }, { .compatible = "microchip,mcp4531-503", .data = &mcp4531_cfg[MCP453x_503] }, ... Or perhaps using a macro? #define MCP4531_COMPATIBLE(of_compatible, cfg) { \ .compatible = of_compatible, \ .data = &mcp4531_cfg[cfg], \ } and then MCP4531_COMPATIBLE("microchip,mcp4531-502", MCP453x_502), MCP4531_COMPATIBLE("microchip,mcp4531-103", MCP453x_103), MCP4531_COMPATIBLE("microchip,mcp4531-503", MCP453x_503), ... Pick any of those, and you have my ack. Maybe Jonathan has an opinion on which is best? End of bikeshed...
