[PATCH 0/2] DT updates for Cubox-i

[PATCH 0/2] DT updates for Cubox-i

[Russell King - ARM Linux]

Shawn,

These are two updates to the Cubox-i which I'd prefer to get into -rc.
They were omitted from the merge window because their dependent changes
were not merged, but have now been merged.

The only real functional change for the Cubox-i in this set is that it
is now possible to control the front panel LED.  The other patch is
solely about moving some DT configuration to where it belongs.

Can we please get these in?

Thanks.

[PATCH 1/2] ARM: dts: cubox-i: add support for PWM-driven front panel LED

[Russell King]

The front panel LED on the Cubox-i is driven by one of the iMX6 PWM
channels, and is wired between the PWM output and supply.

[PATCH 2/2] ARM: dts: hummingboard/cubox-i: move usb otg configuration to platform level

[Russell King]

The configuration of the USB OTG is a platform configuration decision,
not a microsom decision.  Move this configuration out to the platform
level files.

Okay, I will send them together with the fixes I queued for -rc.
