These changes from 30 individual branches for the most part update device tree files, but there are also a few source code changes that have crept in this time, usually in order to atomically move over a driver from using hardcoded data to DT probing. A number of platforms change their DT files to use the C preprocessor, which is causing a bit of churn, but that is hopefully only this once. There are a few conflicts with the other branches unfortunately: * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added from multiple branches. Need to be careful to have the right set of closing braces as git gets this one wrong. * In kirkwood.dtsi, one 'ranges' line got split into two lines, while another line got added. Order of the lines does not matter. * in sama5d3.dtsi, some cleanup was merged the wrong way, causing a bogus conflict. We want the 'dmas' and 'dma-names' properties to get added here. * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUdLnpGCrR//JCVInAQI50RAAsXbH1SGvjKJemXhRkFloPDYpCbgdDUFr ChUbjNV1xsY/jaNCfMa5/Qo7lgz/Ot7BpJef9fZn7ret+dc7nchqe/4iIkAokAUh E4ao9D1dP5aAA0ihdbSQHCZtR/0SUR81h6BoOVuo/1mvEiBaFbWAeYe8/6LJd9II OU1w9bDmjfZWYFUXs+j2VF76ueZQ+kz69XDKZUGtkqN76m1AL8lGDurj5jxvyllF VJns8d9q2nr2q9PferfajK6rkOIPaTpwKblxZHUgobCyOitZaiZM0NgF733TsNM6 HXmhDhkcn7T81+SiHVfigJ/nxo9UgU4zNJCODF3WZIwGIj3FbxvCOpdCYi2NhCO8 oLcgDk57tpoKpB3gvAmYVQHP9FIepFa/WAWyPIADA7PkpYrwgc4v+cLEHXpd8SRv viLLIa5QuNdMeaK+Md9OKmKZFd7uFD9jiMtmdm6IpEVDDjMgoteb2XSoEtNebmtY MfbW4okn118a2dFKKaPTKcXVW/a5FRp2JGfB0A58RQHaJWj3JsY1bFn/xWPEpTOA IWB/HHMln0LYTL2AXN9HcaL1jnGI1Wq5eWBurX+cXQ/ij1A6jfoRKYglx7AQqOHj iWcGYtKLLJCgiWFnLSwcljZhfoYr0/z7rhns6yo7/vhN0riy+M84OgN4HbAmUzc1 Bgy9PnJTNo8= =8PtJ -----END PGP SIGNATURE----- Merge tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree changes from Arnd Bergmann: "These changes from 30 individual branches for the most part update device tree files, but there are also a few source code changes that have crept in this time, usually in order to atomically move over a driver from using hardcoded data to DT probing.
