Subject: [RFC 0/5] OMAP3: convert opp-v1 to opp-v2 and read speed binned / 720MHz grade bits

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 high speed OPPs) on:
* BeagleBoard C2 (omap3430 600MHz)
* BeagleBoard XM B (dm3730 800MHz)
* GTA04A4 (dm3730 800MHz)
* GTA04A5 (dm3730 1GHz)

H. Nikolaus Schaller (5):
  cpufreq: ti-cpufreq: add support for omap34xx and omap36xx
  ARM: dts: add support for opp-v2 for omap34xx and omap36xx
  ARM: dts: omap3-evm-37xx: fix compatible from omap3630 to omap36xx
  ARM: dts: omap3-n950-n9: remove opp-v1 table
  ARM: dts: omap3-beagle: make explicitly compatible to ti,omap34xx
