Subject: [PATCH v2] ARM: dts: Add pwm-fan node to the Odroid-U3 board
Date: Tue, 04 Nov 2014 11:23:41 +0100 [thread overview]
Message-ID: <1415096622-20550-1-git-send-email-k.debski@samsung.com> (raw)
Add pwm-fan node to the Odroid-U3 board file to enable PWM control of the
cooling fan. In addition, add the "pwm" label to the pwm@139D0000 node
in the exynos4412.dtsi.
Signed-off-by: Kamil Debski <k.debski@samsung.com>

Changes since v1:
- added pwm label to the pwm@139D0000 node in exynos4.dtsi
- use the pwm label in the exynos4412-odroidu3.dts
- change order or properties in the pwn-fan node, to be sorted
in alphabetical order
