Subject: [PATCH] arm64: dts: sun50i-a64-pinephone: improve brightness values
|
||
|
|
on BH/CE
|
||
|
|
|
||
|
|
Commit aad90c10 caused a brightness increase with the previous values.
|
||
|
|
Subsequently, the lowest brightness value would still be fairly bright.
|
||
|
|
|
||
|
|
This commit aims at providing a wider range of usable brightness for
|
||
|
|
1.1+ devices.
|
||
