ARM: dts: dra7: Add ti-opp-supply nodes and enable 1.5 GHz

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

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?

Regards,

Tony

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

Regards,
Dave

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

Regards,

Tony

Add the OPP supply node for the MPU voltage rail to provide the information needed by the ti-opp-supply driver to enable AVS Class 0.

After ti-opp-supply driver is in place to provide AVS Class0 and abb regulator scaling support let's enable 1.5GHz for the cpu.
