Could we have an architecture discussion about how this is supposed to be done
and a picture please !
(a pointer to good working code would be nice)
On brownstone the SDIO 8787 power is supplied by a ldo which is dedicated to
the internal SDIO chip.
The Power GPIO (PDn) is an on/off switch fo
During card removal and inserting cycle the test file in the debugfs could be
stalled until the host driver removes it. Let's keep the file in the linked
list and destroy it when card is removed.

Hi all,
I have a question about latency and SDIO, since many laptops don't
have a 'gameport' anymore and I want to do realtime IO, I was thinking
of making a SDIO GPIO card.
I know USB is a no go, if not using buffers for outgoing data ... so
SDIO is a desperate mans hope.

For Freescale eSDHC registers only support 32-bit accesses,
this patch ensure that all Freescale eSDHC register accesses
are 32-bit.
