This is no regression and we need to fix it. Right, we need to move on to device tree based booting. Most of it should be pretty trivial configuring of the .dts file and some .config changes so whatever issues are remaining should be out of the way by v3.11. > So my first step was to follow the recipe given in that commit. > Beside that I noticed a thread about USB issue on LKML so I also > applied the following commit: > > commit 352f573e59050c7a604c35c58b4bbfc51edebbee > Author: Roger Quadros <rogerq@xxxxxx> > Date: Tue Jun 18 19:04:47 2013 +0300 > > ARM: OMAP2+: Provide alias to USB PHY clock > > The attached kernel log seems to suggest that the device tree is > picked up by the kernel, but the USB does not seem very active.

Roger can point you to the current versions that Benoit should be queueing for the -rc series. Then for the SDIO with device tree, take a look at the following patches: [PATCH 0/3] WLAN support for omap4 when booted with devicetree http://comments.gmane.org/gmane.linux.ports.arm.omap/97522# The wl12xx .dts changes for pandaboard are still missing too. Then I'll be updating these soonish: [PATCH 0/4] Updated omap_hsmmc SDIO and remuxing patches Those are needed for the SDIO interrupt, SDIO will work also without those.
