Subject: [PATCH] arm:dt:msm8994 Correct regulator timming
|
||
|
|
|
||
|
|
Documentation describe slew-rate as "time in us it takes for the regulator to change votlage value in one step".
|
||
|
|
2s seems a lot and qpnp-lab-slew-rate is only 5000us.
|
||
|
|
So correct it as if a 1000 factor was added.
|
||
|
|
|
||
|
|
This reduce the kernel boot time of the karin windy by 80s
|
||
|
|
Tested on karin windy only
