[PATCH 1/2] arm: omap: craneboard: Add USB EHCI support

From: Felipe Balbi <hidden>
Date: 2010-12-23 08:50:30

From: Srinath <redacted>

AM3517/05 Craneboard has one EHCI interface on board using port1.

GPIO35 is used as power enable.
GPIO38 is used as port1 PHY reset.

[PATCH 2/2] arm: omap: tusb6010: add name for MUSB IRQ

From: Felipe Balbi <hidden>
Date: 2010-12-23 08:50:31

commit fcf173e4511193b1efeccb0f22a8c641b464353b
(add names for IRQs in structure resource)
forgot to take care of tusb6010 making it
fail to probe due to a missing resource.

Fix it.

[GIT PULL] OMAP USB Changes for Merge Window

From: tony@atomide.com (Tony Lindgren)

Hi Tony,

please queue the following two patches for Merge Window.

The following changes since commit b79540fcbbcf9b379c9197f63c5a883bbe3adfd4:

   Linux-omap rebuilt: Merged branches from Paul and Kevin and mux changes (2010-12-22 19:13:33 -0800)
This can't be pulled as it would pull in tons of non-mainline
commits from the linux-omap master branch.

Everybody, all the pullable branches must be based on something
in the mainline kernel, like a recent -rc tag. If that won't work,
then some commit needs to be agreed on separately that will go
to mainline, like the omap-for-linus branch.

Further, please wait few days before sending the pull request
in case somebody wants to ack your patches. Sending a pull request
with the patches to be reviewed is kind of pointless.. Sure in this
case these are pretty trivial patches, but still.

Anyways, I'll apply these into a temporary branch and will
merge into omap-for-linus within next few days assuming no
problems.

Regards,

Tony

heh, my bad. Craneboard wasn't in mainline then I rebased on top of your
tree.

Makes sense.
Further, please wait few days before sending the pull request
in case somebody wants to ack your patches. Sending a pull request
with the patches to be reviewed is kind of pointless.. Sure in this
the patches were actually for reference, much like Greg does with the
USB patches.
case these are pretty trivial patches, but still.
patch 1 was pending on l-o for weeks, only patch 2 is new.
Anyways, I'll apply these into a temporary branch and will
merge into omap-for-linus within next few days assuming no
problems.
good, thanks.
