Pull MIPS updates from Ralf Baechle: - Improvements to the tlb_dump code - KVM fixes - Add support for appended DTB - Minor improvements to the R12000 support - Minor improvements to the R12000 support - Various platform improvments for BCM47xx - The usual pile of minor cleanups - A number of BPF fixes and improvments - Some improvments to the support for R3000 and DECstations - Some improvments to the ATH79 platform support - A major patchset for the JZ4740 SOC adding support for the CI20 platform - Add support for the Pistachio SOC - Minor BMIPS/BCM63xx platform support improvments. - Avoid "SYNC 0" as memory barrier when unlocking spinlocks - Add support for the XWR-1750 board. - Paul's __cpuinit/__cpuinitdata cleanups. - New Malta CPU board support large memory so enable ZONE_DMA32. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (131 commits) MIPS: spinlock: Adjust arch_spin_lock back-off time MIPS: asmmacro: Ensure 64-bit FP registers are used with MSA MIPS: BCM47xx: Simplify handling SPROM revisions MIPS: Cobalt Don't use module_init in non-modular MTD registration. MIPS: BCM47xx: Move NVRAM driver to the drivers/firmware/ MIPS: use for_each_sg() MIPS: BCM47xx: Don't select BCMA_HOST_PCI MIPS: BCM47xx: Add helper variable for storing NVRAM length MIPS: IRQ/IP27: Move IRQ allocation API to platform code. MIPS: Replace smp_mb with release barrier function in unlocks. MIPS: i8259: DT support MIPS: Malta: Basic DT plumbing MIPS: include errno.h for ENODEV in mips-cm.h MIPS: Define GCR_GIC_STATUS register fields MIPS: BPF: Introduce BPF ASM helpers MIPS: BPF: Use BPF register names to describe the ABI MIPS: BPF: Move register definition to the BPF header MIPS: net: BPF: Replace RSIZE with SZREG MIPS: BPF: Free up some callee-saved registers MIPS: Xtalk: Update xwidget.h with known Xtalk device numbers ... |

To understand all the Linux-USB framework, you'll use these resources: * This source code. This is necessarily an evolving work, and includes kerneldoc that should help you get a current overview. ("make pdfdocs", and then look at "usb.pdf" for host side and "gadget.pdf" for peripheral side.) Also, Documentation/usb has more information. * The USB 2.0 specification (from www.usb.org), with supplements such as those for USB OTG and the various device classes. The USB specification has a good overview chapter, and USB peripherals conform to the widely known "Chapter 9". * Chip specifications for USB controllers. Examples include host controllers (on PCs, servers, and more); peripheral controllers (in devices with Linux firmware, like printers or cell phones); and hard-wired peripherals like Ethernet adapters. * Specifications for other protocols implemented by USB peripheral functions. Some are vendor-specific; others are vendor-neutral but just standardized outside of the www.usb.org team. Here is a list of what each subdirectory here is, and what is contained in them. core/ - This is for the core USB host code, including the usbfs files and the hub class driver ("hub_wq"). host/ - This is for USB host controller drivers. This includes UHCI, OHCI, EHCI, and others that might be used with more specialized "embedded" systems. gadget/ - This is for USB peripheral controller drivers and the various gadget drivers which talk to them. Individual USB driver directories. A new driver should be added to the first subdirectory in the list below that it fits into. image/ - This is for still image drivers, like scanners or digital cameras. ../input/ - This is for any driver that uses the input subsystem, like keyboard, mice, touchscreens, tablets, etc. ../media/ - This is for multimedia drivers, like video cameras, radios, and any other drivers that talk to the v4l subsystem. ../net/ - This is for network drivers. serial/ - This is for USB to serial drivers. storage/ - This is for USB mass-storage drivers. class/ - This is for all USB device drivers that do not fit into any of the above categories, and work for a range of USB Class specified devices. misc/ - This is for all USB device drivers that do not fit into any of the above categories.
