SoC changes, a substantial part of this is cleanup of some of the older platforms that used to have a bunch of board files. In particular: - Removal of non-DT i.MX platforms that haven't seen activity in years, it's time to remove them. - A bunch of cleanup and removal of platform data for TI/OMAP platforms, moving over to genpd for power/reset control (yay!) - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them closer to multiplatform support (not quite there yet, but getting close). THere are a few other changes too, smaller fixlets, etc. For new platform support, the primary ones re: - New SoC: Hisilicon SD5203, ARM926EJ-S platform. - Cpufreq support for i.MX7ULP -----BEGIN PGP SIGNATURE----- iQJDBAABCgAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAl+TT4gPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx322MP/1mI56SyOFx30AqtWBPSjHJp+DzhOObyb4vD ndYuicBIn9tJwvVRBBZkfsbIU8EENVwrN3hOpesaj9L7xiqOqKakcnyC1REYmpIs 8XBDfdZzy5PrMHIu3fF1ZDCQyO7KndGf5DfLVxJtcf1tSPQyQCuIA3FtS6d8Bxnz r491+om67ucnlFD5X0Spm3RdZH+ECmXx2iXwoS0Zi7P+X+S+ovG8wBV/X0ggeoBc Zgi4W01SiRupmSVZ6PA7FvWaLGQErQAALQOcFtMcFgjeWzc1v2QzcURELH8JW7ro 72AH9st1Kvi3hoN2HNNzUnNUdQvZ+AdH8skMIpN/e1cBYqYStAF3gm/R9h+iVHbG GMmgzXHAFErfAW2UcF8tq1CzvQ5ChcTLNXdeoa8CeQbcDfocF3EyuKSPuDH+ve0H kk4tPesTAc6XCEVwLaGnoC75sdum5mSi8h9vqhln2KCdeTY7jxzH9YGHjm71Supb kV9vqo5Q5U/c5l2nU4r5q/DZdIahKsk3HIQZ0iG7BifAzamaTh4uyLVjtM6HSwNz tdHZaxoHd/PLI5IoeggFelx6qgvK5qVRLP0evgOdTLRFLj/ZbrOf0Q7DjdTy2BjZ Lgq461QqNapOzxq43G2IDT2+P62Q1+d+YLCKBgaGQaJicyU5m9STCNo3UBb1qH1h W6UwGF5z =0+Ee -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC platform updates from Olof Johansson: "SoC changes, a substantial part of this is cleanup of some of the older platforms that used to have a bunch of board files.
