Subject: [PATCH] overlays: i2c-sensor: Make smbus-timeout-disable
|
||
|
optional
|
||
|
|
||
|
Although disabling the SMBUS timeout may be useful, not all chips
|
||
|
support it. The driver treats attempting to disable the timeout on a
|
||
|
non-supporting chip as an error, so make it an option enabled using the
|
||
|
no_timeout parameter.
