[PATCH 0/8] ARM: dts: dra7: Add ti-opp-supply nodes and enable 1.5 GHz

[Dave Gerlach]

Hi,
This series adds the additional regulators and ti-opp-supply nodes to enable
ABB regulator scaling and AVS Class0 for dra7 and am57 platforms. In addition
to this the 1.5 GHz OPP is enabled for any platforms in the dra7 and am57
family that support it based on the detection done by the ti-cpufreq driver.

Regards,
Dave

[PATCH 1/8] ARM: dts: dra7: Add vbb-supply to cpu and additional voltages

[Dave Gerlach]

Add a vbb-supply phandle to the cpus node and also add an additional
triplet of voltages for each OPP in the operating-points-v2 table to
make use of the multi regulator support in the OPP core and provide the
vbb regulator for use by the ti-opp-supply driver.

Sounds like these depend on the ti-opp-supply being available first?

Yes that would be best, but the ti-opp-supply patches are already in linux-next.

OK applying into omap-for-v4.16/dt then thanks.
