This branch contains two kinds of updates: Some platforms in the process of getting converted to device tree based booting, and the platform specific patches necessary for that are included here. Other platforms are already converted, so we just need to update the actual device tree source files and the binding documents to add support for new board and new drivers. In the future we will probably separate those into two branches, and in the long run, the plan is to move the device tree source files out of the kernel repository, but that has to wait until we have completed a much larger portion of the binding documents. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIVAwUAUA2dbmCrR//JCVInAQJl0hAA3U3AnfBBXbKEJhUi47z6QU2kRPVfyjAj ct+FsZMWFihEHC5/YkB/bQ/i7Hf/AKBZRG6eAUfsyevuhQ0Li+wsRM4eU3FaF6kw HNqqB6GQWM+2rR8//Y6AAZymTLfe5nbuWFhRXiIggIlQne5jJ1kSidmSzG+OJEuN sAKXX7Ud5goVsby9Uwp4Gc0fpDsjFmIarhHfMDizFozNZIFzZIhKKdl1VOf+Kv+o PFRfCGB2KQrrDy0oB62y3iNUiK84LA0xWX4KkI9rD4OHWeiDQpbUITchf//Wa20X vgZdI8T16sxbmAHi1zerIl8y/CLgLyerp1L3KSMGTwirC+92vZg+jOGYGgNqu973 NOl0IBQFpbAlNzmf52naNgcQ2OxxFQ3ogrlpvE2bItLL7J3vpmn1JwWMTtSrcs3Z xgbovAq2ivNOiKpzXexvMsWDCU3PxzXaP+2hEUhglJcdXkx5Iwiwi6un2FuF2qWT l5rSAWkg2kT/OkgYHLBI5JW7e7ugWhUAuCsrIH9eW7xstm4hIlN950vefs2FrZkP FeE7pn6s6mr98+j9isJKusETXIoEXDLX61vxA8PQP7GYN+/O/g2qB0qztBwarMBL wAdHCjavOYNwPkxYaGLjv9qKt3X575O/6aFa/NoKGhIECanjLl02Tqg02BdHecST 8HENXCvwQns= =K3WL -----END PGP SIGNATURE----- Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull arm-soc device tree description updates from Arnd Bergmann: "This branch contains two kinds of updates: Some platforms in the process of getting converted to device tree based booting, and the platform specific patches necessary for that are included here.
