[PATCH V7 0/8] ARM: OMAP3+: support cpufreq-cpu0 for device tree boot

[Nishanth Menon]

Hi,

This series enables the use of cpufreq-cpu0 generic driver for all
OMAP and related derivatives. Only patch#8 in the series, which
introduces CPU clock nodes, depends on Tero's V8 patch series for clock
nodes[1]

I will stop copy pasting the series complete history and point at [2].

Main changes since V6[3]:
- squashed patches for a minimal set
- i have organized the series such that 1 to 7 can immediately be merged
  if desired:
	- patches 1,2,3 can go to Tony's omap-for-v3.13/quirk [4]
	- patches 4-7 can go to Benoit's for_3.13/dts [5]
	- patch 8 needs to depend on [1] and should eventually go to [5]

NOTES: obviously without clock nodes cpufreq will not function.

[PATCH V7 1/8] ARM: OMAP3+: do not register non-dt OPP tables for device tree boot

[Nishanth Menon]

OMAP3+ supports both device tree and non-device tree boot.
Device tree bindings for OMAP3+ is supposed to be added via dts following:
Documentation/devicetree/bindings/power/opp.txt

Since we now have device tree entries for OMAP3+ cpu OPPs,
The current code wrongly adds duplicate OPPs. So, dont register OPPs
when booting using device tree.

[PATCH V7 2/8] ARM: OMAP2+: add missing lateinit hook for calling pm late init

[Nishanth Menon]

AM335x, AM43xx, OMAP5 and DRA7 have missing late init hook. Introduce
SoC specific hook with a call to OMAP2+ generic lateinit hook. This
allows the generic late initializations such as cpufreq hooks to be
active.

Based on out-of-tree patches that need to be introduced in
mainline, this introduction allows us to provide the foundation for
further SoC specific features as they are developed.

[PATCH V7 3/8] ARM: OMAP3+: use cpu0-cpufreq driver in device tree supported boot

[Nishanth Menon]

With OMAP3+ and AM33xx supported SoC having defined CPU device tree
entries with operating-points and clock nodes defined, we can now use
the SoC generic cpufreq-cpu0 driver by registering appropriate device.

Thanks I'm taking patches 1 - 3 from this series into

The data is based on OMAP543x ES2.0 DM Operating Condition Addendum
Version 0.6(April 2013)

NOTE: The voltage and frequency values work well only on NOM samples
and are supposed to work properly only with ABB/AVS for ALL OPPs.

TODO: Add SPEED BIN OPP after ABB and AVS support so the cpufreq works
on all samples seamlessly. Clock node is pending alignment for clock
dts conversion

I've just applied them in my DTS tree.

Thanks,

Hi Nishanth,

A colleague of mine (Sanjay), was trying mainline on panda board. And
wasn't able to get cpufreq-cpu0 working with it. Even your log also
reports its broken as it can't get any regulator information..

He is getting this:

cpufreq_cpu0: failed to get cpu0 regulator: -19
cpufreq_cpu0: failed to get cpu0 clock: -2
cpufreq-cpu0: probe of cpufreq-cpu0.0 failed with error -2

Can you please help him out?
