[PATCH 0/2] ARM: dts: dra7-evm: Regulator max voltage fixes

[Ravikumar Kattekola]

Hi,

This set does a minor fix and an update:

   - Fix a typo in the max voltage property of smps6 (vdd_gpu) regulator node added by
     the patch : c56a831ca47e ("ARM: dts: DRA7: Add TPS659038 PMIC nodes")

   - Update max voltage property of smps7 (vdd_core) regulator node to align with the 
     latest Data Manual

Regards,
RK

[PATCH 1/2] ARM: dts: dra7-evm: Fix typo in SMPS6 (VDD_GPU) max voltage

[Ravikumar Kattekola]

The max expected voltage for VDD_GPU, connected to SMPS6, is 1.25V.
Correct regulator max voltage constraint to meet this requirement.

Document reference: DRA74 Data Manual, SPRS857M - Dec 2012,
		    Revised Oct 2014.

[PATCH 2/2] ARM: dts: dra7-evm: Update SMPS7 (VDD_CORE) max voltage to match DM

[Ravikumar Kattekola]

As per the latest Data Manual, for newer samples,
the nominal voltage required for VDD_CORE at OPP_NOM can be
upto 1.06V which was 1.03V earlier.

Update the regulator max voltage constraint for SMPS7,
connected to VDD_CORE, to meet this requirement.
