Hi Daniel,

one big request and some more style nitpicks :-)

With the nitpicks fixed
Reviewed-by: Heiko Stuebner <heiko@sntech.de>


Before applying this patch could you drop the rk3288.dtsi change please?
Instead I'd like to add the following patch separately to _my_ devicetree
branch for 3.20.

I already wasn't fast enough to prevent the ethernet controller changes
going through the network tree and would like to prevent a third tree sending
changes for the same dts area to Linus - merge conflicts and all.


I don't think that neither the nitpicks nor dropping the dtsi segment need
another submission though.


Heiko

Subject: [PATCH] ARM: dts: rockchip: Add rockchip timer node for rk3288

The rk3288 board uses the architected timers and these ones are shutdown when
the cpu is powered down. There is a need of a broadcast timer in this case to
ensure proper wakeup when the cpus are in sleep mode and a timer expires.

Add the timer node for the broadcast timer.

Hi Heiko,

I removed the dtsi change, fixed the spaces indentation and pushed in my 
tree the driver [1]

Thanks the review

and I pushed the corresponding dt change to [2] and am going to send the
pull request to arm-soc in the next days.
