2014-12-13ARM / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PMRafael J. Wysocki
After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere in the code under arch/arm/ (the defconfig files will be modified later). Signed-off-by: Rafael J.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Olof Johansson: "This merge window brings a good size of cleanups on various platforms. Among the bigger ones: - Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have lacked active support for quite a while, and after asking around nobody showed interest in keeping them around. If needed, they could be resurrected in the future but it's more likely that we would prefer reintroduction of them as DT and multiplatform-enabled platforms instead. - OMAP4 controller code register define diet. They defined a lot of registers that were never actually used, etc. - Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate) to drivers/soc so it can be shared with 64-bit code. This also converts them over to traditional driver models where possible. - Removal of legacy gpio-samsung driver, since the last users have been removed (moved to pinctrl) Plus a bunch of smaller changes for various platforms that sort of dissapear in the diffstat for the above. clps711x cleanups, shmobile header file refactoring/moves for multiplatform friendliness, some misc cleanups, etc" * tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (117 commits) drivers: CCI: Correct use of ! and & video: clcd-versatile: Depend on ARM video: fix up versatile CLCD helper move MAINTAINERS: Add sdhci-st file to ARCH/STI architecture ARM: EXYNOS: Fix build breakge with PM_SLEEP=n MAINTAINERS: Remove Kirkwood ARM: tegra: Convert PMC to a driver soc/tegra: fuse: Set up in early initcall ARM: tegra: Always lock the CPU reset vector ARM: tegra: Setup CPU hotplug in a pure initcall soc/tegra: Implement runtime check for Tegra SoCs soc/tegra: fuse: fix dummy functions soc/tegra: fuse: move APB DMA into Tegra20 fuse driver soc/tegra: Add efuse and apbmisc bindings soc/tegra: Add efuse driver for Tegra ARM: tegra: move fuse exports to soc/tegra/fuse.h ARM: tegra: export apb dma readl/writel ARM: tegra: Use a function to get the chip ID ARM: tegra: Sort includes alphabetically ARM: tegra: Move includes to include/soc/tegra ...
2014-07-29ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from ↵Uwe Kleine-König
<mach/memory.h> The platforms selecting NEED_MACH_MEMORY_H defined the start address of their physical memory in the respective <mach/memory.h>. With ARM_PATCH_PHYS_VIRT=y (which is quite common today) this is useless though because the definition isn't used but determined dynamically. So remove the definitions from all <mach/memory.h> and provide the Kconfig symbol PHYS_OFFSET with the respective defaults in case ARM_PATCH_PHYS_VIRT isn't enabled. This allows to drop the dependency of PHYS_OFFSET on !NEED_MACH_MEMORY_H which prevents compiling an integrator nommu-kernel. (CONFIG_PAGE_OFFSET which has "default PHYS_OFFSET if !MMU" expanded to "0x" because CONFIG_PHYS_OFFSET doesn't exist as INTEGRATOR selects NEED_MACH_MEMORY_H.)

Commit 193ab2a60700 ("usb: gadget: allow multiple gadgets to be built") apparently required that checks for CONFIG_USB_GADGET_OMAP would be replaced with checks for CONFIG_USB_OMAP. Do so now for the remaining checks for CONFIG_USB_GADGET_OMAP, even though these checks have basically been broken since v3.1. And, since we're touching this code, use the IS_ENABLED() macro, so things will now (hopefully) also work if USB_OMAP is modular.

Pull ARM changes from Russell King: - Perf updates from Will Deacon: - Support for Qualcomm Krait processors (run perf on your phone!) - Support for Cortex-A12 (run perf stat on your FPGA!) - Support for perf_sample_event_took, allowing us to automatically decrease the sample rate if we can't handle the PMU interrupts quickly enough (run perf record on your FPGA!). - Basic uprobes support from David Long: This patch series adds basic uprobes support to ARM. It is based on patches developed earlier by Rabin Vincent. That approach of adding hooks into the kprobes instruction parsing code was not well received. This approach separates the ARM instruction parsing code in kprobes out into a separate set of functions which can be used by both kprobes and uprobes. Both kprobes and uprobes then provide their own semantic action tables to process the results of the parsing. - ARMv7M (microcontroller) updates from Uwe Kleine-König - OMAP DMA updates (recently added Vinod's Ack even though they've been sitting in linux-next for a few months) to reduce the reliance of omap-dma on the code in arch/arm. - SA11x0 changes from Dmitry Eremin-Solenikov and Alexander Shiyan - Support for Cortex-A12 CPU - Align support for ARMv6 with ARMv7 so they can cooperate better in a single zImage. - Addition of first AT_HWCAP2 feature bits for ARMv8 crypto support. - Removal of IRQ_DISABLED from various ARM files - Improved efficiency of virt_to_page() for single zImage - Patch from Ulf Hansson to permit runtime PM callbacks to be available for AMBA devices for suspend/resume as well. - Finally kill asm/system.h on ARM. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (89 commits) dmaengine: omap-dma: more consolidation of CCR register setup dmaengine: omap-dma: move IRQ handling to omap-dma dmaengine: omap-dma: move register read/writes into omap-dma.c ARM: omap: dma: get rid of 'p' allocation and clean up ARM: omap: move dma channel allocation into plat-omap code ARM: omap: dma: get rid of errata global ARM: omap: clean up DMA register accesses ARM: omap: remove almost-const variables ARM: omap: remove references to disable_irq_lch dmaengine: omap-dma: cleanup errata 3.3 handling dmaengine: omap-dma: provide register read/write functions dmaengine: omap-dma: use cached CCR value when enabling DMA dmaengine: omap-dma: move barrier to omap_dma_start_desc() dmaengine: omap-dma: move clnk_ctrl setting to preparation functions dmaengine: omap-dma: improve efficiency loading C.SA/C.EI/C.FI registers dmaengine: omap-dma: consolidate clearing channel status register dmaengine: omap-dma: move CCR buffering disable errata out of the fast path dmaengine: omap-dma: provide register definitions dmaengine: omap-dma: consolidate setup of CCR dmaengine: omap-dma: consolidate setup of CSDP ...

Export the DMA register information from the SoC specific data, such that we can access the registers directly in omap-dma.c, mapping the register region ourselves as well.

2014-03-21ARM: omap1: don't rely on tps65010Arnd Bergmann
The code for h2 and osk implicitly assumes that the tps65010 driver is built-in, in order to perform the initial regulator setup. This is fine for most real uses, but it does get into the way of build testing with 'make randconfig', since we don't want platforms to implicitly select device drivers and subsystems such as I2C. This patch by contrast changes the board files to not call into the tps65010 driver when that is not built-in, allowing us to build all configurations including some that will not work properly on this hardware.

This patch adds a omap1510_fpga_init_irq() inline dummy implementations in arch/arm/mach-omap1/common.h. Without this patch,build system can lead to issues. This was discovered during randconfig testing,in which other than CONFIG_ARCH_OMAP15XX was enabled the leading to the following error: CC arch/arm/mach-omap1/board-innovator.o arch/arm/mach-omap1/board-innovator.c: In function ‘innovator_init’: arch/arm/mach-omap1/board-innovator.c:377:3: error: implicit declaration of function ‘omap1510_fpga_init_irq’ [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[1]: *** [arch/arm/mach-omap1/board-innovator.o] Error 1 make: *** [arch/arm/mach-omap1] Error 2 Signed-off-by: Manjunath Goudar <csmanjuvijay@gmail.com> Cc: Tony Lindgren <tony@atomide.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: linux-arm-kernel@lists.infradead.org Cc: linux-kernel@vger.kernel.org Cc: linux-omap@vger.kernel.org Signed-off-by: Tony Lindgren <tony@atomide.com>

Cleaning up that code touches multiple subsystems, but gets rid of the dependency in the end. The mailbox code moved out from mach-omap2 to drivers/mailbox is an intermediate step and is still omap specific at the moment.

2013-06-11mailbox/omap: move the OMAP mailbox framework to driversSuman Anna
The mailbox hardware (in OMAP) uses a queued mailbox interrupt mechanism that provides a communication channel between processors through a set of registers and their associated interrupt signals by sending and receiving messages. The OMAP mailbox framework/driver code is moved to be under drivers/mailbox, in preparation for adapting to a common mailbox driver framework. This allows the build for OMAP mailbox to be enabled (it was disabled during the multi-platform support). As part of the migration from plat and mach code: - Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers. - mailbox.h under plat-omap/plat/include has been split into a public and private header files. The public header has only the API related functions and types. - The module name mailbox.ko from plat-omap is changed to omap-mailbox.ko - The module name mailbox_mach.ko from mach-omapX is changed as mailbox_omap1.ko for OMAP1 mailbox_omap2.ko for OMAP2+ Cc: Tony Lindgren <tony@atomide.com> [gregkh@linuxfoundation.org: ack for staging part] Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Omar Ramirez Luna <omar.ramirez@copitl.com> Signed-off-by: Suman Anna <s-anna@ti.com>
