Subject: [PATCH] arm/boot/dts/overlays/mipi-dbi-spi: fix default brightness
|
|
(#5442)
|
|
|
|
There is an off-by-one error in the default brightness for the PWM backlight
|
|
in the MIPI DBI SPI overlay that produces the following message in the
|
|
kernel logs:
|
|
|
|
pwm-backlight backlight_pwm: invalid default brightness level: 16, using 15
|
|
|
|
The value is 0-based, so the max brightness is 15, not 16.
