[PATCH v2] Convert i.MX architecture to generic clock framework

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

Hi All,

Here is another round of patches to convert i.MX to the generic clock
framework. It is based on Mikes recently published for-next branch plus:

[PATCH V3 1/8] CLKDEV: Add helper routines to allocate and add clkdevs for given struct clk *
[PATCH V3 2/8] clk: add a fixed factor clock
clkdev: Implement managed clk_get()

The branch is tested on all SoCs I have available, but regressions are more
than likely, so please give it a test.

I didn't move the clock support to drivers/clk now as the clock control
module is shared with several other SoC specific stuff and I need a global
spinlock. Accessing this somewhere from drivers/ seems odd. Depending on
how things work out we can move it to drivers/ later.

The remaining cleanups like removing the old clock support posted in the
last series are not included here, I will respin them once it's clear that
a series goes in

For your convenience a complete series including dependencies (so not
meant for upstream) can be pulled here:

Thanks
