Subject: [PATCH] ARM: dts: Fix LEDs on exynos5422-odroidxu3
Date: Wed, 2 Sep 2015 23:48:08 +0900 [thread overview]
Message-ID: <1441205288-22047-1-git-send-email-k.kozlowski.k@gmail.com> (raw)
The LEDs on Odroid XU3 family boards could not properly probe because PWM
outputs were reduced only to PWM for fan. Fix this to:
- Odroid XU3 and XU3-Lite: 4 outputs (although the PWM for MIPI
probably is redundant because board does not have MIPI connector
available);
- Odroid XU4: 2 outputs.
This fixes warnings on dmesg:
[ 4.838712] samsung-pwm 12dd0000.pwm: tried to request PWM channel 1 without output
[ 4.838725] leds_pwm pwmleds: unable to request PWM for green:mmc0: -22
[ 4.838767] leds_pwm: probe of pwmleds failed with error -22
