Hi David,

This series converts mach-davinci to use the common clock framework.
The series works like this, the first 3 patches fix some issues with
the clock
drivers that have already been accepted into the mainline kernel.
Then, starting with "ARM: davinci: pass clock as parameter to
davinci_timer_init()", we get the mach code ready for the switch by
adding the
code needed for the new clock drivers and adding #ifndef
CONFIG_COMMON_CLK
around the legacy clocks so that we can switch easily between the old
and the
new.
"ARM: davinci: switch to common clock framework" actually flips the
switch
to start using the new clock drivers. Then the next 8 patches remove all
of the old clock code.
The final four patches add device tree clock support to the one SoC that
supports it.
This series has been tested on TI OMAP-L138 LCDK (both device tree
and legacy
board file).
If you do end up sending a v12, you can leave out the mach-davinci
portions unless there are any changes you need to make. I will pick them
up from this series once the driver dependencies are merged.
I do hope the drivers/clk/* changes can be merged from v4.18.
I have resent all of the clk patches (including all of the ones I listed as
dependencies in addition to the three remaining in this series) under the
cover "clk: davinci: outstanding fixes".
I also found that we need to add power-domains properties to the PWM nodes
in "ARM: dts: da850: Add clocks". I probably should just take your advice
and just globally added them even if they are not documented for some types
ofnodes.
I think doing it en masse will be controversial. Just add it to PWM
nodes for now (I am assuming the binding documentation agrees).
I have applied this series so please send any more changes as follow-on
patches.
Thanks
Sekhar
FYI, there are some CPU frequency scaling patches that I was playing around
with, but I don't plan on submitting them since they aren't much use to me
at the moment. If anyone would like to pick them up, you can find them at
https://github.com/dlech/linux/tree/da850-dt-cpufreq.
