Commit b6e0703b (mmc: omap: make it behave well as a module) made some
__devinit changes but missed one function causing a section warning:
WARNING: vmlinux.o(.devinit.text+0x8604): Section mismatch in reference
from the function mmc_omap_probe)
The function __devinit mmc_omap_probe() references a
I have started looking at this area and I am rather confused. It seems to me
two "dedicated" regulators are required.
One regulator controls VDD (vcc) and this is the regulator called vmmc. This
regulator MAY support the ability to switch voltages and MAY support the
ability to be turned on

The sd host controller spec indicates the the MAX_CURRENT value may be
returned as 0. In this case other methods need to be used to return
the current. If 0 is returned and there is a regulator, ask the regulator
for how much current is available.

max_current_caps can return 0 if not available from the sd controller.
if no regulator is present or the regulator specifies a current
less then 200ma we will set the 200ma caps bit by default.
do not do this.

We have h/w that does not support 1.8v signaling even though the
controller does support this. If we enable 1.8v support UHS
cards are recognised but recovery to 3.3v is not possible
depending on the SD card.
Ensure that when we do not support 1.8v UHS mode cards can
