These changes are all driver specific and cross over between arm-soc contents and some other subsystem, in these cases cpufreq, crypto, dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have these changes merged through arm-soc. As we proceed to untangle the dependencies between platform code and driver code, the amount of changes in this category is fortunately shrinking, for 3.11 we have 16 branches here and 101 non-merge changesets, the majority of which are for the stedma40 dma engine driver used in the ux500 platform. Cleaning up that code touches multiple subsystems, but gets rid of the dependency in the end. The mailbox code moved out from mach-omap2 to drivers/mailbox is an intermediate step and is still omap specific at the moment. Patches exist to generalize the subsystem and add other drivers with the same API, but those did not make it for 3.11. Conflicts: * In cpu-db8500.c results from the removal of the u8500_of_init_devices function in combination with the split of u8500_auxdata_lookup. * In arch/arm/mach-omap2/devices.c, the includes got reshuffled. we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUdLnomCrR//JCVInAQJI/A/9FydsQa9sdnzLFgcdX5BeRRwkXLfDifCM zDTfUBo+LriKOs7QHblmDg1MnY1UMB2IfrdHD0FsjK7WbZ/91EMAGDPYcI7Fu4+u pGStxwWi2v+oCT1jjeOkCPT7hdCqogsSpybYq8itSb+zdvdOi6U35dWEKz8xGqz4 vTL9gTZbJP0kowkjIcaryk7FIj7BTIvMCW8n55JZEkDe0BuSJGYn5c3Mntut12ZK 5xM2PeNe2sd3dIdA6XbM2ye/XmYa8xY8Qu4/ijxfH1gnJLvz9Unp96nRXpEbIeMb BH2Sro8dxsMCaweIQhSRKGnUWMYO/Rh7/+5EqzJ163Ezthx9nvHXJY2ndWuD7uM1 IcGrMxLtqP22TEMtZAVEATDp/5ymxEo5GM+eayUojQDn213wOJjRs5xz5IBsH4KM 8CM/gpadWmLjWku72yEV4lryLcdS0NVQzpTnEbILEGOU4u7qJtxRAp7x7tWBtFg8 4m/eWcSVk/U2SYbXmQHsfukuWgKY0cnZbctPcdnaqXwTP7toJEAK3gxoMtWh49Jq 2M2PVFyFejaaq5b/71wAJ7ePYw56H0N/F3RsGpPE55AY15++gSoQ+3t2Si68hDw8 NtyJMkQYpTvtqJbHXWpQQ3Zfs7pDBe01WDV7i+m4JTNggxUDaO/t1Fqp+fEksm4J r+luEf5Gcgk= =mJsI -----END PGP SIGNATURE----- Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver specific changes from Arnd Bergmann: "These changes are all driver specific and cross over between arm-soc contents and some other subsystem, in these cases cpufreq, crypto, dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have these changes merged through arm-soc.
