2014-11-26clocksource: armada-370-xp: Use the reference clock on A375 SoCEzequiel Garcia
The 25 MHz reference clock has better stability so its use is preferred over the core clock. This commit takes advantage of the already introduced Armada 375 devicetree compatible string and adds a new timer initialization. If available, the timer will use the reference clock (named as 'fixed'). Otherwise, it falls back to the previous behavior.

2014-11-26of: Add NVIDIA Tegra memory controller bindingThierry Reding
The memory controller on NVIDIA Tegra exposes various knobs that can be used to tune the behaviour of the clients attached to it. In addition, the memory controller implements an SMMU (IOMMU) which can translate I/O virtual addresses to physical addresses for clients. This is useful for scatter-gather operation on devices that don't support it natively and for virtualization or process separation. Signed-off-by: Thierry Reding <treding@nvidia.com>

2014-11-26drm: imx: Move imx-drm driver out of stagingPhilipp Zabel
The imx-drm driver was put into staging mostly for the following reasons, all of which have been addressed or superseded: - convert the irq driver to use linear irq domains - work out the device tree bindings, this lead to the common of_graph bindings being used - factor out common helper functions, this mostly resulted in the component framework and drm of_graph helpers. Before adding new fixes, and certainly before adding new features, move it into its proper place below drivers/gpu/drm.

Most of the commits contained here are sparse or coccinelle fixes ranging from missing 'static' to returning 0 in case of errors. More importantly, we have the removal the now unnecessary 'driver' argument to ->udc_stop(). DWC2 learned about Dual-Role builds. Users of this IP can now have a single driver built for host and device roles. DWC3 got support for two new HW platforms: Exynos7 and AMD. The Broadcom USB 3.0 Device Controller IP is now supported and so is PLX USB338x, which means DWC3 has lost is badge as the only USB 3.0 peripheral IP supported on Linux. Thanks for Tony Lindgren's work, we can now have a distro-like kernel where all MUSB glue layers can be built into the same kernel (statically or dynamically linked) and it'll work in PIO (DMA will come probably on v3.20). Other than these, the usual set of cleanups and non-critical fixes. Signed-off-by: Felipe Balbi <balbi@ti.com>

2014-11-24of/overlay: Introduce DT overlay supportPantelis Antoniou
Overlays are a method to dynamically modify part of the kernel's device tree with dynamically loaded data. Add the core functionality to parse, apply and remove an overlay changeset. The core functionality takes care of managing the overlay data format and performing the add and remove. Drivers are expected to use the overlay functionality to support custom expansion busses commonly found on consumer development boards like the BeagleBone or Raspberry Pi. The overlay code uses CONFIG_OF_DYNAMIC changesets to perform the low level work of modifying the devicetree. Documentation about internal and APIs is provided in Documentation/devicetree/overlay-notes.txt v2: - Switch from __of_node_alloc() to __of_node_dup() - Documentation fixups - Remove 2-pass processing of properties - Remove separate ov_lock; just use the DT mutex. v1: - Drop delete capability using '-' prefix. The '-' prefixed names are valid properties and nodes and there is no need for it just yet. - Do not update special properties - name & phandle ones. - Change order of node attachment, so that the special property update works.

2014-11-24ipvlan: Initial check-in of the IPVLAN driver.Mahesh Bandewar
This driver is very similar to the macvlan driver except that it uses L3 on the frame to determine the logical interface while functioning as packet dispatcher. It inherits L2 of the master device hence the packets on wire will have the same L2 for all the packets originating from all virtual devices off of the same master device. This driver was developed keeping the namespace use-case in mind. Hence most of the examples given here take that as the base setup where main-device belongs to the default-ns and virtual devices are assigned to the additional namespaces. The device operates in two different modes and the difference in these two modes in primarily in the TX side. (a) L2 mode : In this mode, the device behaves as a L2 device. TX processing upto L2 happens on the stack of the virtual device associated with (namespace). Packets are switched after that into the main device (default-ns) and queued for xmit. RX processing is simple and all multicast, broadcast (if applicable), and unicast belonging to the address(es) are delivered to the virtual devices. (b) L3 mode : In this mode, the device behaves like a L3 device. TX processing upto L3 happens on the stack of the virtual device associated with (namespace). Packets are switched to the main-device (default-ns) for the L2 processing. Hence the routing table of the default-ns will be used in this mode. RX processins is somewhat similar to the L2 mode except that in this mode only Unicast packets are delivered to the virtual device while main-dev will handle all other packets. The devices can be added using the "ip" command from the iproute2 package - ip link add link <master> <virtual> type ipvlan mode [ l2 | l3 ] Signed-off-by: Mahesh Bandewar <maheshb@google.com> Cc: Eric Dumazet <edumazet@google.com> Cc: Maciej Żenczykowski <maze@google.com> Cc: Laurent Chavey <chavey@google.com> Cc: Tim Hockin <thockin@google.com> Cc: Brandon Philips <brandon.philips@coreos.com> Cc: Pavel Emelianov <xemul@parallels.com> Signed-off-by: David S.

2014-11-23clk: sunxi: Implement A31 PLL6 as a divs clock for 2x outputChen-Yu Tsai
Some clock modules on the A31 use PLL6x2 as one of their inputs. This patch changes the PLL6 implementation for A31 to a divs clock, i.e. clock with multiple outputs that have different dividers. The first output will be the normal PLL6 output, and the second will be PLL6x2. This patch fixes the PLL6 N factor in the clock driver, and removes any /2 dividers in the PLL6 factors clock part. The N factor counts from 1 to 32, mapping to values 0 to 31, as shown in the A31 manual. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

2014-11-23irqdomain: Introduce new interfaces to support hierarchy irqdomainsJiang Liu
We plan to use hierarchy irqdomain to suppport CPU vector assignment, interrupt remapping controller, IO-APIC controller, MSI interrupt and hypertransport interrupt etc on x86 platforms. So extend irqdomain interfaces to support hierarchy irqdomain. There are already many clients of current irqdomain interfaces. To minimize the changes, we choose to introduce new version 2 interfaces to support hierarchy instead of extending existing irqdomain interfaces. According to Thomas's suggestion, the most important design decision is to build hierarchy struct irq_data to support hierarchy irqdomain, so hierarchy irqdomain related data could be saved in struct irq_data. With support of hierarchy irq_data, we could also support stacked irq_chips. This is most useful in case of set_affinity(). The new hierarchy irqdomain introduces following interfaces: 1) irq_domain_alloc_irqs()/irq_domain_free_irqs(): allocate/release IRQ and related resources. 2) __irq_domain_alloc_irqs(): a special version to support legacy IRQs. 3) irq_domain_activate_irq()/irq_domain_deactivate_irq(): program interrupt controllers to activate/deactivate interrupt. There are also several help functions to ease irqdomain implemenations: 1) irq_domain_get_irq_data(): get irq_data associated with a specific irqdomain. 2) irq_domain_set_hwirq_and_chip(): save irqdomain specific data into irq_data. 3) irq_domain_alloc_irqs_parent()/irq_domain_free_irqs_parent(): invoke parent irqdomain's alloc/free callbacks. We also changed irq_startup()/irq_shutdown() to invoke irq_domain_activate_irq()/irq_domain_deactivate_irq() to program interrupt controller when start/stop interrupts.
