			This branch contains a set of device-tree conversions for Marvell Orion platforms that were staged early but took a few tries to get the branch into a format where it was suitable for us to pick up. Given that most people working on these platforms are hobbyists with limited time, we were a bit more flexible with merging it even though it came in late. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQGrp8AAoJEIwa5zzehBx3Ou8P/3HA53sS2WotNsBjpGTPuJim TppOmfFU6e7TLaY2oOWjIb5tPxK96u4vvCnQFAv+9TF+ewW0yCQlkBIJga3uVE7+ tlz5TbKBo+vQYrFgFCpEwwTHYuLgjpIK4wDs+09EkIM4cMqe6RnLK1KGo6vCAqO9 CKE0rqEfUFjdUq2jed7HA39iwNqJrz8VGLviozvTjW2R42x9iGuy5m2DpThYrLzr 7IYwKGMaJIatG1C/pai7KLEjdJgQl9PeDsgG0oyYY2HHeNy3o8m7tLOL3tnWXeyj XaniNs/YZBp4nADf2sCzXxEVjqRBPVyiw8qCHEOW5L1cfUTq//1QDI3I4kcQzffg VsfLPNvzFsPEMlLI1Xo5UX/8w3xQhBeoI8PtlX7coBMBLn5rJXGnjGpEnH+5SsSA 8KXxm4hP2aOGF+injoEv5HCEiUngH4YPN4hgXwyYdJKcln2YHy8xoIVabsmx27+v bSfododiEvHsBNxfz0Nn5Vo5O3trubU3qe4FEBAhS3pU3GksBocokAqtxeR+BBbH RfBVJ09QEYx1N+c6bhGQXt7F+8sUYO0s9tA7BEkeJtiXp8OX6M8eE4mFoMpIJbsC SmyxsVEE9pna9x3TSy42jiGO3yxbuKEoAy2HfyU1R8yq84XBFXbkgwV02tQcgClz vH4VgGdQoGULqa83GImG =xb8w -----END PGP SIGNATURE----- Merge tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull arm-soc Marvell Orion device-tree updates from Olof Johansson: "This contains a set of device-tree conversions for Marvell Orion platforms that were staged early but took a few tries to get the branch into a format where it was suitable for us to pick up.
