This is the bulk of new SoC enablement and other platform changes for 3.17: * Samsung S5PV210 has been converted to DT and multiplatform * Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms * Kirkwood, one of the popular Marvell platforms, is folded into the mvebu platform code, removing mach-kirkwood. * Hwmod data for TI AM43xx and DRA7 platforms. * More additions of Renesas shmobile platform support * Removal of plat-samsung contents that can be removed with S5PV210 being multiplatform/DT-enabled and the other two old platforms being removed. New platforms (most with only basic support right now): * Hisilicon X5HD2 settop box chipset is introduced * Mediatek MT6589 (mobile chipset) is introduced * Broadcom BCM7xxx settop box chipset is introduced + as usual a lot other pieces all over the platform code. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJT5Dp+AAoJEIwa5zzehBx3w1sP/0vjT/LQOmC8Lv8RW2Ley2ua hNu3HcNPnT/N40JEdU9YNv3q0fdxGgcfKj011CNN+49zPSUf1xduk2wfCAk9yV50 8Sbt1PfDGm1YyUugGN420CzI431pPoM1OGXHZHkAmg+2J286RtUi3NckB//QDbCY QhEjhpYc9SXhAOCGwmB4ab7thOljOFSPzKTLMTu3+PNI5zRPRgkDkt6w9XlsAYmB nuR271BnzsROkMzAjycwaJ3kdim7wqrMRfk8g96o0jHSF5qf4zsT5uWYYAjTxdUQ 8Ajz6zjeHe4+95TwTDcq+lCX6rDLZgwkvCAc6hFbeg0uR7Dyek0h6XMEYtwdjaiU KNPwOENrYdENNDAGRpkFp1x4h/rY9Plfru0bBo5o6t7aPBvmNeCDzRtlTtLiUNDV dG8sfDMtrS/wFHVjylDSQ60Mb+wuW0XneC8D7chY/iRhIllUYi6YXXvt+/tH5C20 oYDOWqqcDFSb0sJhE5pn4KBV82ZaHx9jMBWGLl+erg2sDX/SK8SxOkLqKYZKtKB5 0leOGE3Y+C70xt3G9HftLz2sAvvt+C8UPsApPT+dHNE401TWJOYx6LphPkQKjeeK P1iwKi+It3l+FaBypgJy/LeMQRy7EyvDBK2I5WoVL/R2qq14EmP1ui3Tthjj0bhq tBBof6P9c8OnRVj1Lz3R =5TJ6 -----END PGP SIGNATURE----- Merge tag 'soc-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform changes from Olof Johansson: "This is the bulk of new SoC enablement and other platform changes for 3.17: - Samsung S5PV210 has been converted to DT and multiplatform - Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms - Kirkwood, one of the popular Marvell platforms, is folded into the mvebu platform code, removing mach-kirkwood - Hwmod data for TI AM43xx and DRA7 platforms - More additions of Renesas shmobile platform support - Removal of plat-samsung contents that can be removed with S5PV210 being multiplatform/DT-enabled and the other two old platforms being removed New platforms (most with only basic support right now): - Hisilicon X5HD2 settop box chipset is introduced - Mediatek MT6589 (mobile chipset) is introduced - Broadcom BCM7xxx settop box chipset is introduced + as usual a lot other pieces all over the platform code" * tag 'soc-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (240 commits) ARM: hisi: remove smp from machine descriptor power: reset: move hisilicon reboot code ARM: dts: Add hix5hd2-dkb dts file.
