Also included are some cleanups where the platform maintainers hadn't separated cleanups from new developent in separate branches. Some of the larger things worth pointing out: - A large set of changes from Alexandre Belloni and Nicolas Ferre preparing at91 platforms for multiplatform and cleaning up quite a bit in the process. - Removal of CSR's "Marco" SoC platform that never made it out to the market. We love seeing these since it means the vendor published support before product was out, which is exactly what we want! New platforms this release are: - Conexant Digicolor (CX92755 SoC) - Hisilicon HiP01 SoC - CSR/sirf Atlas7 SoC - ST STiH418 SoC - Common code changes for Nvidia Tegra132 (64-bit SoC) We're seeing more and more platforms having a harder time labelling changes as cleanups vs new development -- which is a good sign that we've come quite far on the cleanup effort. So over time we might start combining the cleanup and new-development branches more" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (124 commits) ARM: at91/trivial: unify functions and machine names ARM: at91: remove at91_dt_initialize and machine init_early() ARM: at91: change board files into SoC files ARM: at91: remove at91_boot_soc ARM: at91: move alternative initial mapping to board-dt-sama5.c ARM: at91: merge all SOC_AT91SAM9xxx ARM: at91: at91rm9200: set idle and restart from rm9200_dt_device_init() ARM: digicolor: select syscon and timer ARM: zynq: Simplify SLCR initialization ARM: zynq: PM: Fixed simple typo.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduce kprobeopt for ARM 32. Limitations: - Currently only kernel compiled with ARM ISA is supported. - Offset between probe point and optinsn slot must not larger than 32MiB. Masami Hiramatsu suggests replacing 2 words, it will make things complex. Futher patch can make such optimization. Kprobe opt on ARM is relatively simpler than kprobe opt on x86 because ARM instruction is always 4 bytes aligned and 4 bytes long. This patch replace probed instruction by a 'b', branch to trampoline code and then calls optimized_callback(). optimized_callback() calls opt_pre_handler() to execute kprobe handler. It also emulate/simulate replaced instruction. When unregistering kprobe, the deferred manner of unoptimizer may leave branch instruction before optimizer is called. Different from x86_64, which only copy the probed insn after optprobe_template_end and reexecute them, this patch call singlestep to emulate/simulate the insn directly. Futher patch can optimize this behavior.

* | ARM/PCI: Move to generic PCI domainsLorenzo Pieralisi2014-12-271-0/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most if not all ARM PCI host controller device drivers either ignore the domain field in the pci_sys_data structure or just increment it every time a host controller is probed, using it as a domain counter. Therefore, instead of relying on pci_sys_data to stash the domain number in a standard location, ARM pcibios code can be moved to the newly introduced generic PCI domains code, implemented in commits: 41e5c0f81d3e ("of/pci: Add pci_get_new_domain_nr() and of_get_pci_domain_nr()") 670ba0c8883b ("PCI: Add generic domain handling") ARM code is made to select PCI_DOMAINS_GENERIC by default, which builds core PCI code that assigns the domain number through the generic function: void pci_bus_assign_domain_nr(...) that relies on a DT property to define the domain number or falls back to a counter according to a predefined logic; its usage replaces the current domain assignment code in PCI host controllers present in the kernel.

Arch independent code provides this functionality so that arch dependent bootloaders can make use of it. Helper functions are provided to get/set symbol values in purgatory which are used by bootloaders later to set things like stack and entry point of second kernel etc. Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Cc: Borislav Petkov <bp@suse.de> Cc: Michael Kerrisk <mtk.manpages@gmail.com> Cc: Yinghai Lu <yinghai@kernel.org> Cc: Eric Biederman <ebiederm@xmission.com> Cc: H.

Most of this is plumbing for various device bindings and new platforms, but there's also a bit of cleanup and code removal for things that are moved from platform code to DT contents (some OMAP clock code in particular). There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable. I'm happy to say that there were no conflicts at all with this branch this release, which means that changes are flowing through our tree as expected instead of merged through driver maintainers (or at least not done with conflicts). There are several new boards added, and a couple of SoCs. In no particular order: - Rockchip RK3288 SoC support, including DTS for a dev board that they have seeded with some community developers. - Better support for Hardkernel Exynos4-based ODROID boards. - CCF conversions (and dtsi contents) for several Renesas platforms. - Gumstix Pepper (TI AM335x) board support - TI eval board support for AM437x - Allwinner A23 SoC, very similar to existing ones which mostly has resulted in DT changes for support. Also includes support for an Ippo tablet with the chipset. - Allwinner A31 Hummingbird board support, not to be confused with the SolidRun i.MX-based Hummingboard. - Tegra30 Apalis board support" * tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (334 commits) ARM: dts: Enable USB host0 (EHCI) on rk3288-evb ARM: dts: add rk3288 ehci usb devices ARM: dts: Turn on USB host vbus on rk3288-evb ARM: tegra: apalis t30: fix device tree compatible node ARM: tegra: paz00: Fix some indentation inconsistencies ARM: zynq: DT: Clarify Xilinx Zynq platform ARM: dts: rockchip: add watchdog node ARM: dts: rockchip: remove pinctrl setting from radxarock uart2 ARM: dts: Add missing pinctrl for uart0/1 for exynos3250 ARM: dts: Remove duplicate 'interrput-parent' property for exynos3250 ARM: dts: Add TMU dt node to monitor the temperature for exynos3250 ARM: dts: Specify MAX77686 pmic interrupt for exynos5250-smdk5250 ARM: dts: cypress,cyapa trackpad is exynos5250-Snow only ARM: dts: max77686 is exynos5250-snow only ARM: zynq: DT: Remove DMA from board DTs ARM: zynq: DT: Add CAN node ARM: EXYNOS: Add exynos5260 PMU compatible string to DT match table ARM: dts: Add PMU DT node for exynos5260 SoC ARM: EXYNOS: Add support for Exynos5410 PMU ARM: dts: Add PMU to exynos5410 ...
