Cover letter [PATCH RFC 0/3] first pass converting omap4 clock data to DT
Hi Mike,
Quoted 4 lines · Mike Turquette
This is a very incomplete conversion of a handful of OMAP4 PRCM clocks from the statically defined clock data in
arch/arm/mach-omap2/cclock44xx_data.cto a new dts file inarch/arm/boot/dts/omap4-clocks.dtsi.
I gave a quick try for this set and it seems to be working nicely, so for at least me this approach is fine. Feel free to add tested-by me if you like (for the basic clock bindings also.) Can't comment much on the DT stuff though as my experience is rather limited on it.

I am not a DT expert so many of the choices here may be quite disgusting to look at, or may be on the right path. In particular I simply include the new
omap4-clocks.dtsifromomap4.dtsi, which feels a bit kludgey. Also this series depends on the basic clock bindings RFC I posted earlier today[1].I actually have an
omap4-clock.dtsifile with many more clocks converted to the mux-clock, divider-clock, fixed-clock, fixed-factor and (unpublished) gate-clock bindings in my local repo, but it is not currently booting. I wanted to get this early preview out regardless.
Any way I can get access to your local tree? Can you push a branch somewhere? I could provide you debugging support on this at least, as I spent quite a bit of time earlier moving the clock data under drivers/clk... I guess you are probably seeing similar issues I faced.
