Subject: [PATCH] mmc: Parse new binding for eMMC fixed driver type
Parse the new binding and store it in the mmc config struct after doing some sanity checks. The code is designed to support fixed mmc driver type if we ever need that.

Has the bindings been accepted by Linux Kernel?
The bindings "fixed-emmc-driver-type" has already included in the Linux Kernel. The others, "fixed-emmc-driver-type-hs200" and "fixed-emmc-driver-type-hs400" are not included in the Linux Kernel.
