There are some failure with build up on timer driver for rockchip.

The problem was different semantics of dsb on btw arm32 and arm64,
Here we can convert the dsb with insteading of dsb(sy).The "sy" param
is the default which you are allow to omit, so on arm32 dsb()and
dsb(sy)
are the same.

as you have "just" Acked these patches, I guess you are expecting them
to go
through the same tree as the devicetree changes, right?

I'm wonder if someone will apply this series patchs but the wait.:-)
In fact, I'm no sure that the Acked is really meaning.:-

Yes, by acking the patch I say I am ok with it and I agree it can go
through another tree.

although I guess the two clocksource changes could very well just go
through your tree. dsb() -> dsb(sy) is supposed to be equal and the second one is just cosmetics. The Kconfig and dts changes need to wait in any case for 4.5 ... but I guess that may be true for the clocksource changes as well?

Heiko, Caesar,

I am wondering if the dsb() is really necessary. Is it possible you test the timer by removing this instruction ? Otherwise I will have to setup my board again and it will take awhile.


As the @Arnd suggestion,

That's seem ok for me.
Although the writel_relaxed() and writel() a bit different with DSB() and L2's sync.

Do I need send the patch v3?  I will test that on my board.

I'm no sure that why the clocksource driver didn't use the writel_relaxed() to work.
Okay, I think we should according to the suggestion or required.
