- eSDHC supports two reference clocks (platform clock and peripheral clock).
- Peripheral clock which could provide higher clock frequency is required to
- be used for tuning of SD UHS mode and eMMC HS200/HS400 modes.
+ When eSDHC operates at 3.3v, damage can accumulate in an internal
+ level shifter at a higher than expected rate. The faster the interface
+ runs, the more damage accumulates. This issue now is found on LX2160A
+ eSDHC1 for only SD card. The hardware workaround is recommended to use
+ an on-board level shifter that is 1.8v on SoC side and 3.3v on SD card
+ side. For boards without hardware workaround, this option could be
+ enabled, ensuring 1.8v IO voltage and disabling eSDHC if no card.
+ This option assumes no hotplug, and u-boot has to make all the way to
+ to linux to use 1.8v UHS-I speed mode if has card.
