* Documentation: arm: Replace use of virt_to_phys with __pa_symbolGeert Uytterhoeven2017-07-171-1/+1
| | | | | | | | | | | | All low-level PM/SMP code using virt_to_phys() should actually use __pa_symbol() against kernel symbols. Update the documentation to move away from virt_to_phys().

* / bus: arm-ccn: Correct required arguments for XP PMU eventsPawel Moll2016-08-171-6/+10
|/ | | | | | | | | | | | | | | | XP can provide events from two sources: watchpoints, observing traffic on device ports and PMU looking at internal buses. Unfortunately the sysfs definition of the PMU events was requiring port number (instead of bus number) and direction (the buses are unidirectional), as these fields were shared with the watchpoint event. Although it does not introduce a major problem (port can be used as bus alias and direction is simply ignored for XP PMU events), it's better to fix it now, before external tools start depending on this behaviour.

It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only. Both of these platforms are now multiplatform. Finally, a couple of patches from Russell for Dove PMU, and a fix from Valentin Rothberg for Exynos ADC, which were rebased on top of the series to avoid conflicts" * tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (75 commits) ARM: realview: don't select SMP_ON_UP for UP builds ARM: s3c: simplify s3c_irqwake_{e,}intallow definition ARM: s3c64xx: fix pm-debug compilation iio: exynos-adc: fix irqf_oneshot.cocci warnings ARM: realview: build realview-dt SMP support only when used ARM: realview: select apropriate targets ARM: realview: clean up header files ARM: realview: make all header files local ARM: no longer make CPU targets visible separately ARM: integrator: use explicit core module options ARM: realview: enable multiplatform ARM: make default platform work for NOMMU ARM: debug-ll: move DEBUG_LL_UART_EFM32 to correct Kconfig location ARM: defconfig: use correct debug_ll settings ARM: versatile: convert to multi-platform ARM: versatile: merge mach code into a single file ARM: versatile: switch to DT only booting and remove legacy code ARM: versatile: add DT based PCI detection ARM: pxa: mark ezx structures as __maybe_unused ARM: pxa: mark raumfeld init functions as __maybe_unused ...

This workaround is not needed on other K2 devices such as K2HK and K2E and with this fix, we can remove the workaround altogether. netcp driver on K2L uses linked ram on OSR (On chip Static RAM) and requires the clock to this peripheral enabled for proper functioning. This is the reason for the kernel crash. So add the clock node to fix this issue. While at it, remove the workaround documentation as well.

This is not scalable as user has to change the DTS if they need upgrade to a new firmware. Instead, add the firmware file name in the driver itself. As long as there is no API change, new firmware upgrade is easy and require no driver change. User is expected to copy the firmware image to the file system and add a sym link to the new firmware for doing an upgrade. Driver add a array of firmware file names to search for the available firmware blobs. This scheme also prepare the driver for future changes to API if ever happens. In such case it is assumed that driver needs to change to accommodate the new firmware and new firmware file name will get added to the array. Also update the DT document to remove the firmware attribute and add description about firmware in the driver documentation.

Changes include: - Enable imprecise aborts early, so that bus errors aren't masked until later in the boot. This has the side effect that boot loaders which provoke these aborts can cause the kernel to crash early in boot, so we install a handler to report this event around the site where these are enabled. - Remove the buggy but impossible to enable cmpxchg syscall code. - Add unwinding annotations to some assembly code. - Add support for atomic half-word exchange for ARMv6k+. - Reduce ioremap() alignment for SMP/LPAE cases where we don't need the large alignment. - Addition of an "optimal" 3G configuration for systems with 1G of RAM. - Increase vmalloc space by 128M. - Constify some SMP operations structures, which have never been writable. - Improve ARMs dma_mmap() support for mapping DMA coherent mappings into userspace. - Fix to the NMI backtrace code in the IPI case on ARM where the failing CPU gets stuck for 10s waiting for its own IPI to be delivered. - Removal of legacy PM support from the AMBA bus driver. - Another fix for the previous fix of vdsomunge" * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (23 commits) ARM: 8449/1: fix bug in vdsomunge swab32 macro arm: add missing of_node_put ARM: 8447/1: catch pending imprecise abort on unmask ARM: 8446/1: amba: Remove unused callbacks for legacy system PM ARM: 8443/1: Adding support for atomic half word exchange ARM: clean up TWD after previous patch ARM: 8441/2: twd: Don't set CLOCK_EVT_FEAT_C3STOP unconditionally ARM: 8440/1: remove obsolete documentation ARM: make highpte an expert option ARM: 8433/1: add a VMSPLIT_3G_OPT config option ARM: 8439/1: Fix backtrace generation when IPI is masked ARM: 8428/1: kgdb: Fix registers on sleeping tasks ARM: 8427/1: dma-mapping: add support for offset parameter in dma_mmap() ARM: 8426/1: dma-mapping: add missing range check in dma_mmap() ARM: remove user cmpxchg syscall ARM: 8438/1: Add unwinding to __clear_user_std() ARM: 8436/1: hw_breakpoint: remove unnecessary header ARM: 8434/2: Revert "7655/1: smp_twd: make twd_local_timer_of_register() no-op for nosmp" ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000 ARM: 8430/1: use default ioremap alignment for SMP or LPAE ...
