I have a question about MCIMX6SLEVK.
Please see the schematics of MCIMX6SLEVK, VDD_HIGH_IN is supplied by MMPF0100 SW2, and VDD_SNVS_IN is supplied by MMPF0100 VSNVS.
These voltage are different (SW2=3.15V, VSNVS=3.0V), so I guessed SW2 output voltage is changed to 3.0V by u-boot same as VGEN5 on SABRE-SD.
However, there is no code to change the SW2 voltage in u-boot for MCIMX6SLEVK.
Is this no problem even though "VDD_HIGH_IN must match the range of voltages that the rechargeable backup battery supports" according Table 9 of IMX6SLCEC Rev.3.
(I understand "rechargeable buckup battery support" = VDD_SNVS_IN)
