Since there's sometimes a dependency on device-tree changes, there's also a fair amount of those in this branch. Pieces worth mentioning are: - Mbus driver for Marvell platforms, allowing kernel configuration and resource allocation of on-chip peripherals. - Enablement of the mbus infrastructure from Marvell PCI-e drivers. - Preparation of MSI support for Marvell platforms. - Addition of new PCI-e host controller driver for Tegra platforms - Some churn caused by sharing of macro names between i.MX 6Q and 6DL platforms in the device tree sources and header files. - Various suspend/PM updates for Tegra, including LP1 support. - Versatile Express support for MCPM, part of big little support. - Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7) - OMAP2+ support for DRA7, a new Cortex-A15-based SoC.

2012-12-24ARM: delete struct sys_timerStephen Warren
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-10-24ARM: davinci: convert platform code to use clk_prepare/clk_unpreparem-karicheri2@ti.com
As a first step towards migrating davinci platforms to use common clock framework, replace all instances of clk_enable() with clk_prepare_enable() and clk_disable() with clk_disable_unprepare(). Until the platform is switched to use the CONFIG_HAVE_CLK_PREPARE Kconfig variable, this just adds a might_sleep() call and would work without any issues. This will make it easy later to switch to common clk based implementation of clk driver from DaVinci specific driver.

Remove individual platform header files for dm365, dm355, dm644x and dm646x and consolidate it into a single and common header file davinci.h placed in arch/arm/mach-davinci. This reduces the pollution in the include/mach and is consistent with Russell's suggestions as part of his "pet peaves" mail. (See #4 in: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/071516.html) While at it, fix the forward declaration of spi_board_info, and include the right header file instead.

2011-09-11mtd: nand: rename NAND_USE_FLASH_BBTBrian Norris
Recall the recently added prefix requirements: * "NAND_" for flags in nand.h, used in nand_chip.options * "NAND_BBT_" for flags in bbm.h, used in nand_chip.bbt_options or in nand_bbt_descr.options Thus, I am changing NAND_USE_FLASH_BBT to NAND_BBT_USE_FLASH. Again, this flag is found in bbm.h and so should NOT be used in the "nand_chip.options" field.

2011-09-11mtd: nand: consolidate redundant flash-based BBT flagsBrian Norris
This patch works with the following three flags from two headers (nand.h and bbm.h): (1) NAND_USE_FLASH_BBT (nand.h) (2) NAND_USE_FLASH_BBT_NO_OOB (nand.h) (3) NAND_BBT_NO_OOB (bbm.h) These flags are all related and interdependent, yet they were in different headers. Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.
