[PATCH 0/3] ARM: Kirkwood: Add DT support for (eSATA) Sheevaplug

[gmbnomis@gmail.com (Simon Baatz)]

These patches add DT support for the Sheevaplugs by Globalscale
Technologies.  There exists two versions, one with an eSATA port and
one without.

Surprisingly, the conversion was not straight forward. In the eSATA
version (board revision 1.3), the CD and WP pins are connected to GPIO
lines, but I could not get this to work.  Apparently, I am not the only
one ([1]).  I found that the pins are reversed on my hardware and use
different active low/active high settings.

Thus, the first patch adds support for the GPIO active low/high flag in
DT to the mvsdio driver.

With that, everything except the Gigabit Ethernet can be described in
the DTS.  I have split the DTS and the board support files into two
patches.  This way, we can drop the last patch once we can describe
everything in the DTS or we can squash them together if we don't want
to wait.

I could only test on an eSATA Sheevaplug. I found patches with
different LEDs for the Sheevaplug.  Thus, I would highly appreciate if
someone with the hardware could give this a spin on a non-eSATA
version.  Some additional testing of the change detect and write
protect behaviour for sdio can't hurt either.  I hope that there aren't
board revisions with different CD/WP pins out there.
