arm-soc: device tree conversions
These are device tree conversions for a number of platforms, with the intention of turning code from board files into device tree descriptions. Notable changes are: * davinci bindings for pinctrl, MTD, RTC, watchdog and i2c * nomadik bindings for all devices, removing the board files * bcm2835 bindings for mmc and i2c * tegra bindings for hdmi, keyboard, audio, as well as some updates * at91 bindings for hardware ecc and for devices on RM9200 * mxs bindings for cfa100xx * sunxi support for Miniand Hackberry board -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUSUyRWCrR//JCVInAQKjPg/6AlHFCcLd2ZNjbp/br9uY9VGDTXC8XBJP aIlEIujOi8PZUzyOK+RfAbMtI9EYlFIM1angoQE2x4E8Wf/5bh0zMD1qdsndhceV acBGcUug4hv1OBFU+VZNNHu+WzcbiWIwNPXGksIOZpgkYJ+6P2BqVdv/HgwdKiJD /Qo5iO6qNeYW387DcVXY5GoDhof56WtsUkb7VrXn5z/ewTq+xu+GuDaAtdsKjHyW hjsAjv6BCCf4fKjxGVhePdVqMtTv3pwVQO0B3DuXdNLESecpTobin/jc+oCSY9Yy LI21KOjjwYYQahwVsNp2sMcfmbVzeOyHqITF/Qt11OY4YtPbf4OBPM61TDqIYlJ3 0PoBtm4AL24wiKSCSiQNn6k7woW531r65lqpGOKYoglGYo50gCvxzsBZYkGzpEkV 7JmUm76Ohppk5QDhO/pIQBFE783IA9rjMg+aPc0SDDwrr499iGBZ2nM7s75MThkm EjHpf4O8JYsXj9KANo9D5cL4zupdnH1jm+qhD8zl9w7EBQXJ6zXy38FaUy04Lgr1 NkHEtwlAeNJ0W6qpu89cNZEaerzeF6uzEFgp06dMwy8X+/NTCLXM1kCJC+mytW83 aFYDlQedqnXeh9fDCrkbYDA8HGKZm0ENxoLOx40iqF761h8cBfhfCIEObClKhXy2 mGBl4NF5ZAU= =NLEa -----END PGP SIGNATURE----- Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree conversions from Arnd Bergmann: "These are device tree conversions for a number of platforms, with the intention of turning code from board files into device tree descriptions.
