This branch contains a number of updates for device tree support on several ARM platforms, in particular: * AT91 continues the device tree conversion adding support for a number of on-chip drivers and other functionality * ux500 adds probing of some of the core SoC blocks through device tree * Initial device tree support for ST SPEAr600 platforms * kirkwood continues the conversion to device-tree probing -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJPcp12AAoJEIwa5zzehBx3c2oQAKkHhJFxYFaUSfAqUNQJtyLP ntNyjANchckGcmoGFRRn5q17leSW+GsPopeJF0uTSOq5xojrQJJnrfKCQmgTtdzt KiD9qJqF3bsM5PxdjkeQljiAirPZSKvyA6gZaPKozZb+NMk3ZMd3hYYi3j3EWR/c 8C9HzwyuXUOKOQ1tHuQHEYnLAtcdVTpUnDGsQItD2Shw5H+AcoN1T00z6kWtXYoJ z/sFtBVvPxqozEEWbTEg2vm0XfT2ENlOIfHoOj+G2EfcVTjh4pSoD0TXwS11vjfX UEniGsdCSkQn0yKVuuLTNKy7BPkWXBUTxy6duIQMSs/57lgFEb9/+f5kgAol+Sdi OeUW4gYkZ8uAk2zOD4p1TGDZT/YHWQ2X3Wq2EhYNsYjZgbNCTlIIocet8jZ6Zfcm f7DdADS8ot8xFcZxMH7CFJ28cmEjhyGMSrMcrAq7HXrkX0ppFutF0CYkY/43uQ/h AGmP9wKi38PB1eXK44eAF25fRvT7ty7CiCBT88i8UZ3unj6raVbsGfqhvf5PbCki oX8dKFjPRRE4bj+8Si7LCTR00AIFMLxuftJw45L4syk+l6Y0y+b0HMBE3E/q7bbR dLBu3V/HHVMnuZv6vVgvI+dkZ9R6v2ychfoyKNh/AKvgXmr90diYbT0XAkcfSPk7 +yy69EZA59UvLTxt9BmN =wiKV -----END PGP SIGNATURE----- Merge tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull "ARM: More device tree support updates" from Olof Johansson: "This branch contains a number of updates for device tree support on several ARM platforms, in particular: * AT91 continues the device tree conversion adding support for a number of on-chip drivers and other functionality * ux500 adds probing of some of the core SoC blocks through device tree * Initial device tree support for ST SPEAr600 platforms * kirkwood continues the conversion to device-tree probing" Manually merge arch/arm/mach-ux500/Kconfig due to MACH_U8500 rename, and drivers/usb/gadget/at91_udc.c due to header file include cleanups.
