Changes V2:
* fix ti-cpufreq to properly describe what compatible string is legacy
* add some reviewed-by and acked-by Tony Lindgren <tony@atomide.com>

PATCH V1 2019-09-07 08:56:19:
* fix typo in omap3-ldp.dts
  (reported by Tony Lindgren <tony@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@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@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@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)


H. Nikolaus Schaller (4):
  cpufreq: ti-cpufreq: add support for omap34xx and omap36xx
  ARM: dts: replace opp-v1 tables by opp-v2 for omap34xx and omap36xx
  ARM: dts: omap3: bulk convert compatible to be explicitly ti,omap3430
    or ti,omap3630 or ti,am3517
  DTS: bindings: omap: update bindings documentation
