vmmc-supply is a defined as:
vmmc-supply = <&v2m_fixed_3v3>;
which is:
v2m_fixed_3v3: fixedregulator@0 {
compatible = "regulator-fixed";
and arch/arm/mach-vexpress/Kconfig says:
menuconfig ARCH_VEXPRESS
[...]
select REGULATOR_FIXED_VOLTAGE if REGULATOR
but it doesn't select REGULATOR in result of this discussion:
http://thread.gmane.org/gmane.linux.ports.arm.kernel/223426/focus=223427
To summarize, I believe that setting CONFIG_REGULATOR=y (as in
vexpress_defconfig) should solve your issue.
