If anyone has any objections, please let me know. ------------------ From: Shawn Lin commit b31ce3041787b61f2dad39d2dcda5c4a81d10e2b upstream. The vcc_sd or vcc_sdio used for IO voltage for sdmmc and sdio interface on rk3399 platform have a limitation that it can't be larger than 3.0v, otherwise it has a potential risk for the chip. Correct all of them.
