of: Drop owner assignment from platform and i2c driver

2015-07-27T13:24:39Z

platform_driver and i2c_driver do not need to set an owner because core will set it. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Rob Herring

of: add HAS_IOMEM depends to OF_ADDRESS

2015-07-27T13:21:04Z

On UML builds, of_address.c fails to compile: ../drivers/of/address.c:873:2: error: implicit declaration of function ‘ioremap’ [-Werror=implicit-function-declaration] This is due to CONFIG_OF now being user selectable. Add a dependency on HAS_IOMEM to OF_ADDRESS in order to fix this. Signed-off-by: Rob Herring Cc: Grant Likely

of/irq: Rename "intc_desc" to "of_intc_desc" to fix OF on sh

2015-06-30T16:03:57Z

Now CONFIG_OF can be enabled on sh: drivers/of/irq.c:472:8: error: redefinition of 'struct intc_desc' include/linux/sh_intc.h:109:8: note: originally defined here As "intc_desc" is used all over the place in sh platform code, while drivers/of/irq.c has a local definition used in a single function, rename the latter by prefixing it with "of_".

of/irq: Fix pSeries boot failure

2015-06-30T15:55:30Z

of_irq_parse_raw() needs to return the correct interrupt controller node when an interrupt-map property doesn't exist. It allows of_irq_parse_raw() to return the node pointer of the interrupt controller, rather than the parent bus. This allows ics_rtas_host_match() to detect that the controller is a legacy 8259 and avoid using xics. This avoids an RTAS assertion/crash during early kernel bootstrapping.

Pull drm updates from Dave Airlie: "This is the main drm pull request for v4.2. I've one other new driver from freescale on my radar, it's been posted and reviewed, I'd just like to get someone to give it a last look, so maybe I'll send it or maybe I'll leave it. There is no major nouveau changes in here, Ben was working on something big, and we agreed it was a bit late, there wasn't anything else he considered urgent to merge. There might be another msm pull for some bits that are waiting on arm-soc, I'll see how we time it. This touches some "of" stuff, acks are in place except for the fixes to the build in various configs,t hat I just applied. Summary: New drivers: - virtio-gpu: KMS only pieces of driver for virtio-gpu in qemu. This is just the first part of this driver, enough to run unaccelerated userspace on. As qemu merges more we'll start adding the 3D features for the virgl 3d work. - amdgpu: a new driver from AMD to driver their newer GPUs. (VI+) It contains a new cleaner userspace API, and is a clean break from radeon moving forward, that AMD are going to concentrate on. It also contains a set of register headers auto generated from AMD internal database. core: - atomic modesetting API completed, enabled by default now. - Add support for mode_id blob to atomic ioctl to complete interface. - bunch of Displayport MST fixes - lots of misc fixes. panel: - new simple panels - fix some long-standing build issues with bridge drivers radeon: - VCE1 support - add a GPU reset counter for userspace - lots of fixes. amdkfd: - H/W debugger support module - static user-mode queues - support killing all the waves when a process terminates - use standard DECLARE_BITMAP i915: - Add Broxton support - S3, rotation support for Skylake - RPS booting tuning - CPT modeset sequence fixes - ns2501 dither support - enable cmd parser on haswell - cdclk handling fixes - gen8 dynamic pte allocation - lots of atomic conversion work exynos: - Add atomic modesetting support - Add iommu support - Consolidate drm driver initialization - and MIC, DECON and MIPI-DSI support for exynos5433 omapdrm: - atomic modesetting support (fixes lots of things in rewrite) tegra: - DP aux transaction fixes - iommu support fix msm: - adreno a306 support - various dsi bits - various 64-bit fixes - NV12MT support rcar-du: - atomic and misc fixes sti: - fix HDMI timing complaince tilcdc: - use drm component API to access tda998x driver - fix module unloading qxl: - stability fixes" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (872 commits) drm/nouveau: Pause between setting gpu to D3hot and cutting the power drm/dp/mst: close deadlock in connector destruction. drm: Always enable atomic API drm/vgem: Set unique to "vgem" of: fix a build error to of_graph_get_endpoint_by_regs function drm/dp/mst: take lock around looking up the branch device on hpd irq drm/dp/mst: make sure mst_primary mstb is valid in work function of: add EXPORT_SYMBOL for of_graph_get_endpoint_by_regs ARM: dts: rename the clock of MIPI DSI 'pll_clk' to 'sclk_mipi' drm/atomic: Don't set crtc_state->enable manually drm/exynos: dsi: do not set TE GPIO direction by input drm/exynos: dsi: add support for MIC driver as a bridge drm/exynos: dsi: add support for Exynos5433 drm/exynos: dsi: make use of array for clock access drm/exynos: dsi: make use of driver data for static values drm/exynos: dsi: add macros for register access drm/exynos: dsi: rename pll_clk to sclk_clk drm/exynos: mic: add MIC driver of: add helper for getting endpoint node of specific identifiers drm/exynos: add Exynos5433 decon driver ...

Pull arm64 updates from Catalin Marinas: "Mostly refactoring/clean-up: - CPU ops and PSCI (Power State Coordination Interface) refactoring following the merging of the arm64 ACPI support, together with handling of Trusted (secure) OS instances - Using fixmap for permanent FDT mapping, removing the initial dtb placement requirements (within 512MB from the start of the kernel image). This required moving the FDT self reservation out of the memreserve processing - Idmap (1:1 mapping used for MMU on/off) handling clean-up - Removing flush_cache_all() - not safe on ARM unless the MMU is off. Last stages of CPU power down/up are handled by firmware already - "Alternatives" (run-time code patching) refactoring and support for immediate branch patching, GICv3 CPU interface access - User faults handling clean-up And some fixes: - Fix for VDSO building with broken ELF toolchains - Fix another case of init_mm.pgd usage for user mappings (during ASID roll-over broadcasting) - Fix for FPSIMD reloading after CPU hotplug - Fix for missing syscall trace exit - Workaround for .inst asm bug - Compat fix for switching the user tls tpidr_el0 register" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (42 commits) arm64: use private ratelimit state along with show_unhandled_signals arm64: show unhandled SP/PC alignment faults arm64: vdso: work-around broken ELF toolchains in Makefile arm64: kernel: rename __cpu_suspend to keep it aligned with arm arm64: compat: print compat_sp instead of sp arm64: mm: Fix freeing of the wrong memmap entries with !SPARSEMEM_VMEMMAP arm64: entry: fix context tracking for el0_sp_pc arm64: defconfig: enable memtest arm64: mm: remove reference to tlb.S from comment block arm64: Do not attempt to use init_mm in reset_context() arm64: KVM: Switch vgic save/restore to alternative_insn arm64: alternative: Introduce feature for GICv3 CPU interface arm64: psci: fix !CONFIG_HOTPLUG_CPU build warning arm64: fix bug for reloading FPSIMD state after CPU hotplug. arm64: kernel thread don't need to save fpsimd context. arm64: fix missing syscall trace exit arm64: alternative: Work around .inst assembler bugs arm64: alternative: Merge alternative-asm.h into alternative.h arm64: alternative: Allow immediate branch as alternative instruction arm64: Rework alternate sequence for ARM erratum 845719 ...
