Subject: [PATCH] hwmon: emc2305: Change OF properties pwm-min &
|
||
|
|
pwm-max to u8
|
||
|
|
|
||
|
|
There is no DT binding for emc2305 as mainline are still
|
||
|
|
discussing how to do a generic fan binding.
|
||
|
|
The 5.15 driver was reading the "emc2305," properties
|
||
|
|
"cooling-levels", "pwm-max", "pwm-min", and "pwm-channel" as u8.
|
||
|
|
The overlay was writing them as u16 (;) so it was working.
|
||
|
|
|
||
|
|
The 6.1 driver was reading as u32, which failed as there is
|
||
|
|
insufficient data.
|
||
|
|
|
||
|
|
As this is all downstream only, revert to u8 to match 5.15.
