It fixes issue with LEDs for Odroid XU3 caused by Anand's b685d540cc26: The offending commit b685d540cc26 was merged in v4.3. I forgot to add "fixes" tag. Fixes: b685d540cc26 ("ARM: dts: Add pwm-fan node for exynos5422-odroidxu3") Can you send it to arm-soc during this cycle? For current v4.3 Bartlomiej's patch is also an important candidate: "ARM: dts: add suspend opp to exynos4412" Best regards, Krzysztof -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

The LEDs on Odroid XU3 family boards could not properly probe because PWM outputs were reduced only to PWM for fan. Fix it for Odroid XU3 and XU3-Lite boards by switching to usage of all 4 outputs (although the PWM for MIPI probably is redundant because board does not have MIPI connector available). 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 Signed-off-by: Krzysztof Kozlowski <k.kozlowski.k@gmail.com> --- Changes since v1: 1.
