CHANGES V3:
* make omap36xx control the abb-ldo and properly switch mode
  (suggested by Adam Ford <aford173 at gmail.com>)
* add a note about enabling the turbo-mode OPPs

PATCH V2 2019-09-07 19:46:58:
* fix ti-cpufreq to properly describe which compatible string is legacy
* add some reviewed-by and acked-by Tony Lindgren <tony at atomide.com>
* include am3517 patches by Adam Ford <aford173 at gmail.com>
* review opp-suspend; and add turbo-mode; opp properties
* add a note how to disable an OPP in a board.dts file

PATCH V1 2019-09-07 08:56:19:
* fix typo in omap3-ldp.dts
  (reported by Tony Lindgren <tony at atomide.com>)
* extend commit message to describe the bit patterns needed
  for opp-supported-hw
* add error check to ioremap()
  (suggested by Christ van Willegen <cvwillegen at gmail.com>)
* update Documentation/devicetree/bindings/arm/omap/omap.txt
* change bulk update to use "ti,omap3430" and "ti,omap3630"
* update OPP4 of omap3430 to 1275 mV since it was not a valid
  voltage for the twl4030 driver (reported by Tony Lindgren
  <tony at atomide.com>)

RFC V2 2019-09-04 10:53:43:
* merge separate patch to remove opp-v1 table from n950-n9 into
  the general omap3xxx.dtsi patch
  (suggested by Viresh Kumar <viresh.kumar at linaro.org>)
* add legacy compatibility to ti,omap3430 and ti,omap3630 for
  the ti-cpufreq driver
* make driver and omap3xxx.dtsi patches pass checkpatch
* add bulk patch to explicitly define compatibility to ti,omap3430
  and ti,omap36xx in addition to ti,omap3 of all in-tree boards
  where it was missing

RFC V1 2019-09-02 12:55:55:

This patch set converts the omap3 opp tables to opp-v2 format
and extends the ti-cpufreq to support omap3.

It adds 720 MHz (omap34xx) and 1 GHz (omap36xx) OPPs but
tells the ti-cpufreq driver to disable them if the speed
binned / 720MHz grade eFuse bits indicate that the chip
is not rated for that speed. 

It has been tested (for chip variant detection, not reliability
of the high speed OPPs) on:

* BeagleBoard C2 (omap3530 600MHz)
* BeagleBoard XM B (dm3730 800MHz)
* GTA04A4 (dm3730 800MHz)
* GTA04A5 (dm3730 1GHz)


Adam Ford (2):
  cpufreq: ti-cpufreq: Add support for AM3517
  ARM: dts: Add OPP-V2 table for AM3517

H. Nikolaus Schaller (6):
  cpufreq: ti-cpufreq: add support for omap34xx and omap36xx
  ARM: dts: omap34xx & omap36xx: replace opp-v1 tables by opp-v2 for
  DTS: bindings: omap: update bindings documentation
  ARM: dts: omap3: bulk convert compatible to be explicitly ti,omap3430
    or ti,omap3630 or ti,am3517
  cpufreq: ti-cpufreq: omap36xx use "cpu0","vbb" if run in
    multi_regulator mode
  ARM: dts: omap36xx: using OPP1G needs to control the abb_ldo
