Re: [PATCH v7 0/7] Implement clocksource for rockchip SoC using rockchip timer

[Alexander Kochetkov]

Hello, Daniel.

Due to recent comments from Mark[1], may be is better to apply v6[2] series instead of v7[3]?
Because my main goal was to fix wall time on rk3188. And I did it the same way how that was
already done for other timer drivers (one of possible solution).

You can rename CLOCKSOURCE_OF to TIMER_OF later. I can help with that, but I donât
think it is good idea to combine my changes and timer framework cleanups/improvements
into single series.

And I thinks, that probably is is better to drop [3] and [4] and revert 0c8893c9095d ("clockevents: Add a
clkevt-of mechanism like clksrc-ofÂ).

What do you think?
