git://github.com/MISL-EBU-System-SW/mainline-public into mvebu/everything Add hardware I/O coherency support for Armada 370/XP The purpose of this patch set is to add hardware I/O Coherency support for Armada 370 and Armada XP. Theses SoCs come with an unit called coherency fabric. A beginning of the support for this unit have been introduced with the SMP patch set. This series extend this support: the coherency fabric unit allows to use the Armada XP and the Armada 370 as nearly coherent architectures. The third patches enables this new feature and register our own set of DMA ops, to benefit this hardware enhancement. The first patches exports a dma operation function needed to register our own set of dma ops. The second patch introduces a new flag for the address decoding configuration in order to be able to set the memory windows as shared memory.
2012-11-21arm: plat-orion: Add coherency attribute when setup mbus targetGregory CLEMENT
Recent SoC such as Armada 370/XP came with the possibility to deal with the I/O coherency by hardware. In this case the transaction attribute of the window must be flagged as "Shared transaction". Once this flag is set, then the transactions will be forced to be sent through the coherency block, in other case transaction is driven directly to DRAM.

2012-09-21arm: plat-orion: introduce PLAT_ORION_LEGACY hidden config optionThomas Petazzoni
Until now, the PLAT_ORION configuration option was common to all the Marvell EBU SoCs, and selecting this option had the effect of enabling the MPP code, GPIO code, address decoding and PCIe code from plat-orion, as well as providing access to driver-specific header files from plat-orion/include. However, the Armada 370 and XP SoCs will not use the MPP and GPIO code (instead some proper pinctrl and gpio drivers are in preparation), and generally, we want to move away from plat-orion and instead have everything in mach-mvebu. That said, in the mean time, we want to leverage the driver-specific headers as well as the address decoding code, so we introduce PLAT_ORION_LEGACY. The older Marvell SoCs need to select PLAT_ORION_LEGACY, while the newer Marvell SoCs need to select PLAT_ORION. Of course, when PLAT_ORION_LEGACY is selected, it automatically selects PLAT_ORION. Then, with just PLAT_ORION, you have the address decoding code plus the driver-specific headers. If you add PLAT_ORION_LEGACY to this, you gain the old MPP, GPIO and PCIe code. Again, this is only a temporary solution until we make all Marvell EBU platforms converge into the mach-mvebu directory. This solution avoids duplicating the existing address decoding code into mach-mvebu.

2012-02-10ARM: orion: Fix Orion5x GPIO regression from MPP cleanupAndrew Lunn
Patchset "ARM: orion: Refactor the MPP code common in the orion platform" broke at least Orion5x based platforms. These platforms have pins configured as GPIO when the selector is not 0x0. However the common code assumes the selector is always 0x0 for a GPIO lines. It then ignores the GPIO bits in the MPP definitions, resulting in that Orion5x machines cannot correctly configure there GPIO lines. The Fix removes the assumption that the selector is always 0x0. In order that none GPIO configurations are correctly blocked, Kirkwood and mv78xx0 MPP definitions are corrected to only set the GPIO bits for GPIO configurations.

A number of these patches could have fit into other branches, too, but were small enough not to cause too much confusion here. * tag 'devel' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (28 commits) mfd/db8500-prcmu: remove support for early silicon revisions ARM: ux500: fix the smp_twd clock calculation ARM: ux500: remove support for early silicon revisions ARM: ux500: update register files ARM: ux500: register DB5500 PMU dynamically ARM: ux500: update ASIC detection for U5500 ARM: ux500: support DB8520 ARM: picoxcell: implement watchdog restart ARM: OMAP3+: hwmod data: Add the default clockactivity for I2C ARM: OMAP3: hwmod data: disable multiblock reads on MMC1/2 on OMAP34xx/35xx <= ES2.1 ARM: OMAP: USB: EHCI and OHCI hwmod structures for OMAP4 ARM: OMAP: USB: EHCI and OHCI hwmod structures for OMAP3 ARM: OMAP: hwmod data: Add support for AM35xx UART4/ttyO3 ARM: Orion: Remove address map info from all platform data structures ARM: Orion: Get address map from plat-orion instead of via platform_data ARM: Orion: mbus_dram_info consolidation ARM: Orion: Consolidate the address map setup ARM: Kirkwood: Add configuration for MPP12 as GPIO ARM: Kirkwood: Recognize A1 revision of 6282 chip ARM: ux500: update the MOP500 GPIO assignments ...

2011-12-20ARM: plat-orion: make gpiochip label uniqueHolger Brunck
The former implementation adds a fix gpiochip label string to the framework. This is confusing because orion_gpio_init is called more than once and this ends up in different gpiochips with the same label. This patch adds the already present orion_gpio_chip_count to the label string to make it unique in the system.

2011-12-18ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtimeMarc Zyngier
sched_clock() is yet another blocker on the road to the single image. This patch implements an idea by Russell King: http://www.spinics.net/lists/linux-omap/msg49561.html Instead of asking the platform to implement both sched_clock() itself and the rollover callback, simply register a read() function, and let the ARM code care about sched_clock() itself, the conversion to ns and the rollover. sched_clock() uses this read() function as an indirection to the platform code. If the platform doesn't provide a read(), the code falls back to the jiffy counter (just like the default sched_clock). This allow some simplifications and possibly some footprint gain when multiple platforms are compiled in. Among the drawbacks, the removal of the *_fixed_sched_clock optimization which could negatively impact some platforms (sa1100, tegra, versatile and omap). Tested on 11MPCore, OMAP4 and Tegra.

2011-12-13ARM: Orion: Get address map from plat-orion instead of via platform_dataAndrew Lunn
Use an getter function in plat-orion/addr-map.c to get the address map structure, rather than pass it to drivers in the platform_data structures. When the drivers are built for none orion platforms, a dummy function is provided instead which returns NULL.
