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 Signed-off-by: Krzysztof Kozlowski <k.kozlowski.k@gmail.com> --- Patch depends/is rebased on latest DTS for Odroid XU4 board: - http://www.spinics.net/lists/arm-kernel/msg442474.html - http://www.spinics.net/lists/arm-kernel/msg442475.html --- arch/arm/boot/dts/exynos5422-odroidxu3-lite.dts | 1 - arch/arm/boot/dts/exynos5422-odroidxu3.dts | 1 - arch/arm/boot/dts/exynos5422-odroidxu4.dts | 2 +- 3 files changed, 1 insertion(+), 3 deletions(-)
