This limitation was put in place because voltage changes were not working correctly, causing the board to stall when attempting higher frequencies. With the recent TPS65219 PMIC driver fixes that properly implement the LOCK register handling, voltage transitions now work reliably. Increase the maximum voltage to 1.3515V to allow the full 1GHz OPP to be used.
