This series converts mach-davinci to use the common clock framework.
Basically, this series does some cleanup and rearranging to get things ready for the conversion. Then there is a patch to add new driver in drivers/clk and finally a patch to make the conversion from the mach clock drivers to the new drivers.
I have tested this on LEGO MINDSTORMS EV3 (TI AM1808), so I am confident that I haven't broken anything (too badly) in da850. But, I don't have other hardware to test.
The one thing that I know I have broken is CPU frequency scaling on da850. I don't think it was working with device tree anyway, so I can't really test it with the hardware I have. I'm hoping that it will be OK to defer fixing it and add device tree support at the same time.
Dependencies: * This series applies on top of "ARM: davinici: move watchdog restart from mach to drivers" [1][2] * On da850, you will also need a patch to prevent problems with the USB PHY clocks [3] * Or get it all at once: git fetch https://github.com/dlech/ev3dev-kernel.git common-clk-v4
[1]: https://patchwork.kernel.org/patch/10105623/ [2]: https://patchwork.kernel.org/patch/10105613/ [3]: https://patchwork.kernel.org/patch/10133193/
v4 changes: * Basically, the whole series is new/reworked except for the first patch. * Instead of having an intermediate conversion of the clocks in mach-davinci, new clock drivers are introduced in drivers/clk. * There are a few more cleanup patches added before making the conversion.
v3 changes: * Remove leftovers from rebasing in "ARM: davinci: don't use static clk_lookup" (fixes compile error)
v2 changes: * Dropped "ARM: davinci: clean up map_io functions" - will resend as separate patch series * Reworked remaining patches so that there is less shuffling around
