Most noteworthy: - Add more Octeon-optimized crypto functions - Octeon crypto preemption and locking fixes - Little endian support for Octeon - Use correct CSR to soft reset Octeons - Support LEDs on the Octeon-based DSR-1000N - Fix PCI interrupt mapping for the Octeon-based DSR-1000N - Mark prom_free_prom_memory() as __init for a number of systems - Support for Imagination's Pistachio SOC. This includes arch and CLK bits. I'd like to merge pinctrl bits later - Improve parallelism of csum_partial for certain pipelines - Organize DTB files in subdirs like other architectures - Implement read_sched_clock for all MIPS platforms other than Octeon - Massive series of 38 fixes and cleanups for the FPU emulator / kernel - Further FPU remulator work to support new features. This sits on a separate branch which also has been pulled into the 4.1 KVM branch - Clean up and fixes for the SEAD3 eval board; remove unused file - Various updates for Netlogic platforms - A number of small updates for Loongson 3 platforms - Increase the memory limit for ATH79 platforms to 256MB - A fair number of fixes and updates for BCM47xx platforms - Finish the implementation of XPA support - MIPS FDC support. No, not floppy controller but Fast Debug Channel :) - Detect the R16000 used in SGI legacy platforms - Fix Kconfig dependencies for the SSB bus support" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (265 commits) MIPS: Makefile: Fix MIPS ASE detection code MIPS: asm: elf: Set O32 default FPU flags MIPS: BCM47XX: Fix detecting Microsoft MN-700 & Asus WL500G MIPS: Kconfig: Disable SMP/CPS for 64-bit MIPS: Hibernate: flush TLB entries earlier MIPS: smp-cps: cpu_set FPU mask if FPU present MIPS: lose_fpu(): Disable FPU when MSA enabled MIPS: ralink: add missing symbol for RALINK_ILL_ACC MIPS: ralink: Fix bad config symbol in PCI makefile.

| * MIPS: BCM47xx: Move NVRAM header to the include/linux/.Rafał Miłecki2015-04-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two reasons for having this header in the common place: 1) Simplifying drivers that read NVRAM entries. We will be able to safely call bcm47xx_nvram_* functions without #ifdef-s. 2) Getting NVRAM driver out of MIPS arch code. This is needed to support BCM5301X arch which also requires this NVRAM driver. Patch for that will follow once we get is reviewed.

Someone may be not interested in extra PCI devices and what's more there are SoCs without any PCI at all (like BCM5356C0, BCM5357*, BCM47186B0). For more details see Kconfig "help".

This was done to avoid having a custom <asm/gpio.h> header for the x86 architecture - GPIO is custom and complicated enough as it is already! We want to move to a radix to store the descriptors going forward, and finally get rid of this fixed array size altogether. - Endgame patching of the gpio_remove() semantics initiated by Abdoulaye Berthe. It is not accepted by the system that the removal of a GPIO chip fails during eg reboot or shutdown, and therefore the return value has now painfully been refactored away. For special cases like GPIO expanders on a hot-pluggable bus like USB, we may later add some gpiochip_try_remove() call, but for the cases we have now, return values are moot. - Some incremental refactoring of the gpiolib core and ACPI GPIO library for more descriptor usage. - Refactor the chained IRQ handler set-up method to handle also threaded, nested interrupts and set up the parent IRQ correctly. Switch STMPE and TC3589x drivers to use this registration method. - Add a .irq_not_threaded flag to the struct gpio_chip, so that also GPIO expanders that block but are still not using threaded IRQ handlers. - New drivers for the ARM64 X-Gene SoC GPIO controller. - The syscon GPIO driver has been improved to handle the "DSP GPIO" found on the TI Keystone 2 SoC:s. - ADNP driver switched to use gpiolib irqchip helpers. - Refactor the DWAPB driver to support being instantiated from and MFD cell (platform device). - Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP, Xilinx and Crystalcove drivers. - Various minor fixes" * tag 'gpio-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (52 commits) gpio: pch: Build context save/restore only for PM pinctrl: abx500: get rid of unused variable gpio: ks8695: fix 'else should follow close brace '}'' gpio: stmpe: add verbose debug code gpio: stmpe: fix up interrupt enable logic gpio: staticize xway_stp_init() gpio: handle also nested irqchips in the chained handler set-up gpio: set parent irq on chained handlers gpiolib: irqchip: use irq_find_mapping while removing irqchip gpio: crystalcove: support virtual GPIO pinctrl: bcm281xx: make Kconfig dependency more strict gpio: kona: enable only on BCM_MOBILE or for compile testing gpio, bcm-kona, LLVMLinux: Remove use of __initconst gpio: Fix ngpio in gpio-xilinx driver gpio: dwapb: fix pointer to integer cast gpio: xgene: Remove unneeded #ifdef CONFIG_OF guard gpio: xgene: Remove unneeded forward declation for struct xgene_gpio gpio: xgene: Fix missing spin_lock_init() gpio: ks8695: fix switch case indentation gpiolib: add irq_not_threaded flag to gpio_chip ...

* | bcma: add support for chipcommon B coreHauke Mehrtens2014-09-095-0/+77
| | | | | | | | | | | | | | | | | | This core is used on BCM4708 to configure the PCIe and USB3 PHYs and it contains the addresses to the Device Management unit. This will be used by the PCIe driver first. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | bcma: store more alternative addressesHauke Mehrtens2014-09-091-4/+5
| | | | | | | | | | | | | | | | | | | | | | Each core could have more than one alternative address. There are cores with 8 alternative addresses for different functions. The PHY control in the Chip common B core is done through the 2. alternative address and not the first one.

| | | | | | | | | | | | | | | | | | | | This is required to split SoC bus init into two phases. The later one (which includes scanning) should be called when kalloc is available.
