Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms. The branch also contains defconfig updates to turn on drivers and options as needed on the various platforms. The largest parts of the delta are from cleanups moving platform data and board file setup of TI platforms to ti-sysc bus drivers. There are also some sweeping changes of eeprom and nand setup on Davinci, i.MX and other platforms. Samsung is removing support for Exynos5440, which was an oddball SoC that hasn't been seen much use in designs. Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D). Linus Walleij is also removing support for ux500 (Sony Ericsson) U8540/9540 SoCs that never made it to significant mass production and products. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlsfCGIPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3Ks8P/3j87Za+6OTCzo+lW2byUy1CI4muGwxNSIxX 65A1Wt2qvRDxjCX4MI5Cx8P1YdYJv+5ZF2p4vdlgQXoz3/XDbG+lxJ+/lyWl/+MK 9kGsQWwEVicbGkaJCYR4ZKvfAwZ9jf7+cndY0Vgii44xQLsQZHEIfIO+mdlK43GZ xqaSckLQQzsDqjMUIckiyVy97RsDk1eLK+H2I+l7qs9v0z5UnhoD2CTxX5LzT8eH NlFmfUPN7Znshmt0aMznZyBRr2oM5Dsg49SfG0WhbOzyiZjSpw8MQ0N+RzyROhhB h5PjyuZN9fx2dO8Jjkqt3B8KmGFNDarGOmrasIJeCJDFRa9NStqFn0y4qJXS2wU7 4La3GoBYRV8x0gq339pQ+70qKuD06e62GL7kV656yi+93CitWxy6IjrIACjSX6zH PD1hQpewfXAcHAHdBqNevRcz/sjG+36GJSCgI4umSP48NMlCuZafFAT4U/PVlt4E 6VRQDeoi5ZFYIuPL1+bZvHax4fFxJGnaf02uQ/OPYP1o48AueSSvdo6bUPFbhwOD u0/uo3r+HxtQsw9I3tP3kj3/775BJclkO6zbG/dGZ8obuzuDwhuFtr3rzCrP/IzN n3rcBuFNZE6SQeKU+Tvmnh8ZLhJc5L8EYvqmihZj+BSfprBc8POFR2la4MRnHSn+ tPEC/n9E =S5wc -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Olof Johansson: "Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms.
