Subject: [RFC v2 0/3] OMAP3: convert opp-v1 to opp-v2 and read speed binned / 720MHz grade bits

Changes V2:
* merge separate patch to remove opp-v1 table from n950-n9 into
  the general omap3xxx.dtsi patch
* 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 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 (omap3430 600MHz)
* BeagleBoard XM B (dm3730 800MHz)
* GTA04A4 (dm3730 800MHz)
* GTA04A5 (dm3730 1GHz)


H. Nikolaus Schaller (3):
  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,omap36xx
