Pull MIPS updates from Ralf Baechle: "This is the main pull request for 4.3 for MIPS. Here's the summary: Three fixes that didn't make 4.2-stable: - a -Os build might compile the kernel using the MIPS16 instruction set but the R2 optimized inline functions in <uapi/asm/swab.h> are implemented using 32-bit wide instructions which is invalid. - a build error in pgtable-bits.h for a particular kernel configuration. - accessing registers of the CM GCR might have been compiled to use 64 bit accesses but these registers are onl 32 bit wide. And also a few new bits: - move the ATH79 GPIO driver to drivers/gpio - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h, change ATH79 accordingly. - fix definition of pgprot_writecombine - add an implementation of dma_map_ops.mmap - fix alignment of quiet build output for vmlinuz link - BCM47xx: Use kmemdup rather than duplicating its implementation - Netlogic: Fix 0x0x prefixes of constants. - merge Bjorn Helgaas' series to remove most of the weak keywords from function declarations. - CP0 and CP1 registers are best considered treated as unsigned values to avoid large values from becoming negative values. - improve support for the MIPS GIC timer. - enable common clock framework for Malta and SEAD3. - a number of improvments and fixes to dump_tlb(). - document the MIPS TLB dump functionality in Magic SysRq. - Cavium Octeon CN68XX improvments. - NetLogic improvments. - irq: Use access helper irq_data_get_affinity_mask. - handle MSA unaligned accesses. - a number of R6-related math-emu fixes. - support for I6400. - improvments to MSA support. - add uprobes support. - move from deprecated __initcall to arch_initcall. - remove finish_arch_switch(). - IRQ cleanups by Thomas Gleixner. - migrate to new 'set-state' interface. - random small cleanups" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (148 commits) MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16.

2015-02-03Documentation: DT bindings: add more Tegra chip compatible stringsPaul Walmsley
Align compatible strings for several IP blocks present on Tegra chips with the latest doctrine from the DT maintainers: http://marc.info/?l=devicetree&m=142255654213019&w=2 The primary objective here is to avoid checkpatch warnings, per: http://marc.info/?l=linux-tegra&m=142201349727836&w=2 DT binding text files have been updated for the following IP blocks: - PCIe - SOR - SoC timers - AHB "gizmo" - APB_MISC - pinmux control - UART - PWM - I2C - SPI - RTC - PMC - eFuse - AHCI - HDA - XUSB_PADCTRL - SDHCI - SOC_THERM - AHUB - I2S - EHCI - USB PHY N.B. The nvidia,tegra20-timer compatible string is removed from the nvidia,tegra30-timer.txt documentation file because it's already mentioned in the nvidia,tegra20-timer.txt documentation file. This second version takes into account the following requests from Rob Herring <robherring2@gmail.com>: - Per-IP block patches have been combined into a single patch - Explicit documentation about which compatible strings are actually matched by the driver has been removed. In its place is implicit documentation that loosely follows Rob's prescribed format: "Must contain '"nvidia,<chip>-pcie", "nvidia,tegra20-pcie"' where <chip> is tegra30, tegra132, ..."

2015-01-29clocksource: devicetree: Document Conexant Digicolor timer bindingBaruch Siach
The Conexant CX92755 SoC provides 8 32-bit timers as part of its so called "Agent Communication" block. Timers can be configures either as free running or one shot. Each timer has a dedicated interrupt source in the CX92755 interrupts controller. The first timer (Timer A) can also be configured as watchdog. This commit adds devicetree binding definition of this hardware module. The binding defined here should be reusable for other SoCs in the Digicolor series.

2015-01-29clockevents: rockchip: Add rockchip timer for rk3288Daniel Lezcano
The rk3288 board uses the architected timers and these ones are shutdown when the cpu is powered down. There is a need of a broadcast timer in this case to ensure proper wakeup when the cpus are in sleep mode and a timer expires. This driver provides the basic timer functionnality as a backup for the local timers at sleep time. The timer belongs to the alive subsystem. It includes two programmables 64 bits timer channels but the driver only uses 32bits. It works with two operations mode: free running and user defined count. Programing sequence: 1. Timer initialization: * Disable the timer by writing '0' to the CONTROLREG register * Program the timer mode by writing the mode to the CONTROLREG register * Set the interrupt mask 2. Setting the count value: * Load the count value to the registers COUNT0 and COUNT1 (not used). 3. Enable the timer * Write '1' to the CONTROLREG register with the mode (free running or user) Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Reviewed-by: Heiko Stuebner <heiko@sntech.de>

2014-11-26clocksource: armada-370-xp: Use the reference clock on A375 SoCEzequiel Garcia
The 25 MHz reference clock has better stability so its use is preferred over the core clock. This commit takes advantage of the already introduced Armada 375 devicetree compatible string and adds a new timer initialization. If available, the timer will use the reference clock (named as 'fixed'). Otherwise, it falls back to the previous behavior.

2014-09-06clocksource: sh_tmu: Document r8a7779 bindingSimon Horman
In general Renesas hardware is not documented to the extent where the relationship between IP blocks on different SoCs can be assumed although they may appear to operate the same way. Furthermore the documentation typically does not specify a version for individual IP blocks. For these reasons a convention of using the SoC name in place of a version and providing SoC-specific compat strings has been adopted. Although not universally liked this convention is used in the bindings for a number of drivers for Renesas hardware. The purpose of this patch is to update the Renesas R-Car Timer Unit (TMU) driver to follow this convention.
