Convert i.MX architecture to generic clock framework

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Hi All,

The following series is the first series converting the complete
i.MX architecture to the generic clock framework. I am currently
waiting for Mike posting his cleanup series to the clock framework
which will cause some adjustments to this series. However, this
series will only need some changes to the interface between i.MX
and the clock framework. The association between the devices and
the clocks (clk_lookup) and also the clocks themselves will stay
unchanged. Due to the huge amount of changes there *will* be
regressions, so now is the time to check if this works with your
favourite devices and boards. I'll happily integrate fixup patches
into this series.

As mentioned before my plan is to put this into the arm-soc staging
area soon (hopefully when Mikes series is posted and acked)

Thanks to Shawn for porting over the i.MX6.
