I would like to ask about power rail design for i.MX6SoloX.
My customer has two questions as below, please give your answers to that.
1. The voltage that fed into NVCC_* of i.MX6SX.
Basically, the customer wants to use 3.3V GPIO, but CSI interface that they want to connect CMOS sensor is 1.8V power.
Then they think that NVCC_CSI_LCD1 should be 1.8V and the other NVCC_* should be 3.3V. Is it alright?
2. The voltage of NVCC_USB_H
i.MX6SX datasheet states that NVCC_USB_H should be connected to GND through 10KOhm in the case of not using HSIC. But the customer wants to use USB_H_DATA pad and USB_H_STROBE pad as I2C signals. In the case of that, should NVCC_USB_H be connected to I2C power rail?
