Those fields are tied to which PMIC is used and it would be extremely surprising to have a disconnect. Sorry, I should have said that I assumed it is a Baytrail CR device because these features: * it's a Z3745 soc * acpi_ipc_irq_index used is 0 (0x1D is the 1st index listed on dsdt, just like other bytcr devices) * ssp0 is being used on this device, not ssp2 * it has a 25mhz clk But these are not enough to state it is a bytcr right?
