Continued device tree conversion and enablement across a number of platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other smaller series as well. ux500 has seen continued conversion for platforms. Several platforms have seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra is adding data for new devices/drivers, and Exynos has a bunch of new bindings and devices added as well. So, pretty much the same progression in the right direction as the last few releases. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQySW7AAoJEIwa5zzehBx39xcP/jzEQOTOJdK4zJd1OjgrQoX/ WnhbGJT941RNjRjvDG6HmZzhpsRoE4q/zkjFEKoKELdikRW0hYoR+zPCGuB7XtN5 aF1ZQrTx4gHf4KE7doIB8slaWeOq8aG2TLFhylyy+cuaIpRK0NG0pAR0ZqWaoga9 tZFciqzplLeo50vZ+y+lVVsR40j/w29EjwPXhCV30//gGOYLyp/VDu5PRtrBdgh8 EgpcT2EWJwMCN/Upcao/q2JbQktPHPpSwnpaUAALYB20uD7k5jo7wtYE/+L9nn6B bxcCDTMVmqzNTF+y0P16hDcs5jMLVjpI0xBiyZ1G6gShpggsSZCHY5ynjAtQ19se r+2WrNfOR23k6arJuOUAQSEnLdx0T5SlW6CJeFEofKv4uoebxAbKUiNO4ShWskhd nNptX1+L3hj3zpjGcEHmL6bd+nGtyMeoG9Yekcv1oZxdVcpKhFxh0s5PEJBEeXcN M7aAWlWJkplV22Olqhpc/3INCweq6E+zBrBxZaUBW/JCzGrqBUGC0BULDPAkmC4J CKL6IqIB73jGQ4OY14IaMU20GJrIGxZ7wzXOp4aw3OUpRlxsgurfyFQeIjUvVoZL PJ8DRoAVwreVHvKfgZZVKpSAY7dwcWbxpWsYlrH3zWIC5vRJ0UFwsD0TpLJWd6Vi XA8gQcJRWKGS8E5mRY39 =Rk9v -----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 and enablement from Olof Johansson: "Continued device tree conversion and enablement across a number of platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other smaller series as well. ux500 has seen continued conversion for platforms.
