This causes an issue with one Toradex SKU that uses a consumer-grade chip that is capable of going up to 1.8GHz at 1.00V. Extend the ranges to min/max values of the SoC operating ranges (table 10) in the datasheet. Detailed explanation as follows: BUCK2: - As already described above, the SKU with the consumer-grade chip needs a voltage of at least 1.00V. 1.05V is chosen now as this is listed as the maximum. Both industrial and consumer-grade chips have an absolute maximum rating of 1.15V which makes it still safe to put 1.05V - Lower the regulator-min value to the smallest value allowed from the Quad-A53, 1.2GHz version of the SoC BUCK3: - This regulator is used for SoC input voltages VDD_GPU, VDD_VPU and VDD_DRAM. - Use the smallest value of these three inputs as the regulator-min - Use the largest value of these three inputs as the regulator-max LDO2: - This LDO is used for VDD_SNVS_0P8 SoC input voltage. As this has a single nominal input voltage just put this in the middle of 0.8V.
