[PATCH v1 0/2] add support in hwmon for MCP998X

Posted by victor.duicu@microchip.com 3 months, 1 week ago

From: Victor Duicu <victor.duicu@microchip.com>

Add support in hwmon for Microchip MCP998X/33 and MCP998XD/33D
Multichannel Automotive Temperature Monitor Family.

The chips in the family have different numbers of external channels,
ranging from 1 (MCP9982) to 4 channels (MCP9985).
Reading diodes in anti-parallel connection is supported by MCP9984/85/33
and MCP9984D/85D/33D. Dedicated hardware shutdown circuitry is present
only in MCP998XD and MCP9933D.

The driver was tested on MCP9984 and MCP9985.
The driver supports reading temperature channels and setting
the update interval.

Differences related to previous patch:
v1:
- initial version for review.
  This is a continuation of the IIO driver:

Huh? That's v1. What are you comparing?
