We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJQznPnAAoJEIqAPN1PVmxKuA8P/0nOJduXFM1c0Gy+DD5DnJnG cXzzeSTV8iO3a3sHIye43QPJ5V2YUR5uxLTUEOo/G7my/MoZ/azeNidkUD3qLVlm wVIq35lcS8dWTZaY7nlpBcWc6e39UB0sEueuJNxyhOv5lnMKdi2tAow5f4vIRQnd Q67/EbrgqdltcOpGmVuCdQcvphvWgy+K65jzbJG5zXs7hGX13Q+M5RnYhx76kc8f TDd0APZ71n5/RyISFSBSu2vfl2kES6o47aMgqqXMEHri6d3puAaXM0rFoMzXg/4G eBdxndN25H7rW7xvt9tuUod2rn1AO7tif5d7jal3Cfj61y3iqKY30yb3OzS9XQXH 9WZ2qDst11zvzQivxIkMGvfRXRfncNLWR4DrBSqVfSbYV2uQj2eS8C6ONwKVMXsQ 5tjNp91PFqN19sWQjIjSMcrNswxgpvdQ9mqFTyOGmISbqrpPSTi+MuO8r9+xTfUF PnzUX2nVOW/i9NcI7uotjzh8jiw6t8XMVHhkehiSYR9hzCb6MaPsFPN4jWq9XA2m 1htCHylNpHqHQ3Mup7Is6j0Li1ahdwfm4lbrgiVEA4t4Mqs5E/Ka+3V8laNAKylW PfCP/VmnJYzmgVTK/qobFNeKzRqR0i4WTL6T7oAxGL87Q4TJaqKpEkXWne8UXV+Q yIbN0fmWfCveCetM+vaf =F790 -----END PGP SIGNATURE----- Merge tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6 Pull MFS update from Samuel Ortiz: "This is the MFD patch set for the 3.8 merge window.
