Subject: [PATCH] overlays: i2c-sensor: Add the jc42 class of sensor
|
|
|
|
This is a second attempt to solve issue 5234, since it turns out that
|
|
the mcp980x driver only supports MCP9800-MCP9803. MCP9804, MCP9805 and
|
|
MCP9808 require the jc42 driver.
|
|
|
|
See: https://github.com/raspberrypi/linux/issues/5234
