SoC updates, mostly refactorings and cleanups of old legacy platforms. Major themes this release: - Conversion of ixp4xx to a modern platform (drivers, DT, bindings) - Moving some of the ep93xx headers around to get it closer to multiplatform enabled. - Cleanups of Davinci This tag also contains a few patches that were queued up as fixes before 5.1 but I didn't get sent in before release. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlzc+sMPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3ygQP/3mxLFGJxgHk6m/41V4Tepv9F2ZZ3BW4Lcp7 vZtr6xiyhZXzIHOGzqQ4VGllfWhMWnjzZZe3iruSBY1gpJU7D4x054T3xVsIDs9F EIcbBm5fE0O0bdijfk7V8vBu7LOIP/KYdaD1n9WDhW0Hy4wTXN8NNLSKEU5Lq15p oz/A3QP5GcwhGAqaHyxx445La9yEKKWAsc2cOCRCdvfw6+n1GpoE6TI1YGjDvqbw xd73mIwXb0l0f7jhCV7OPyZ3t/aQgTD3ddr4gHUGNa8sSWmD5nupSVxj23FkbGby ejqJMxOfHpJJGIL/sxmR3+cFBYxyE+JNmrEq/kDW5ncWs/LY91juJxR1dkQKs6Mj 4Y9CWruftDz34DlFs/J33hF/rdZ73O91ldk7zqND41Fi5aLrIKvZBJlTuqyZ0tGV YNRxsjWF953h8TXimDV0KvBgO4+E8d5ype/kIYtEGYO9DVmXQGMxFx2Gt2I/NfoH 5tCtVFwDPpMxJShpXHLMzUT8sQL3mytg5L/MIPTGx+zAtDwx/qTLEEAElffG29oI vdzgJR0lrG/zzqQh25/M80UZYMdOrwtjAB42C+jAvlfQ0C4DtvSH+8OdcROOgj0b GbAJbTdHYTD6OpoxhSuRii7zzNxw+i7pQj+uLSt8s8ZReGkUk5a2wpRpoVoV2WxK RJHkMK95 =pUeO -----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 updates, mostly refactorings and cleanups of old legacy platforms.
