Our customer have a question about i.MX6DQ SDIO.
They want to use SDIO with 1.8V to connect a Wi-Fi module.
Then, I found the following posts talk about 1.8V SD/MMC.
But I feel the solutions in these posts are the one for when use the SABRE AI schematics.
Our customer don't need SD voltage switching and UHS, and will use 1.8V SDIO with 25MHz.
In this case, what is required to use SDIO = 1.8V?
