dt: bindings: update mvebu-mbus DT binding with new compatible properties

2015-01-09T16:54:28Z

Contrary to what was originally thought, the Armada 375 and Armada 38x MBus windows hardware block is *not* compatible with the Armada 370, due to a difference in how window 13 is handled. It was rather compatible with the Armada XP MBus hardware block. However, the DTs for Armada 375 and Armada 38x encode the following compatible string for MBus: compatible = "marvell,armada375-mbus", "marvell,armada370-mbus", "simple-bus"; compatible = "marvell,armada380-mbus", "marvell,armada370-mbus", "simple-bus"; So, by extending the mvebu-mbus DT binding to also cover the marvell,armada375-mbus and marvell,armada380-mbus compatible strings, we can define a new behavior for those SoCs without changing the DT. Therefore, this commit adds those two new compatible strings to the DT binding documentation of mvebu-mbus. Note that it re-uses two existing duplicated lines for the armada370-mbus and armadaxp-mbus compatible strings. Signed-off-by: Thomas Petazzoni Signed-off-by: Andrew Lunn

Pull networking updates from David Miller: 1) New offloading infrastructure and example 'rocker' driver for offloading of switching and routing to hardware. This work was done by a large group of dedicated individuals, not limited to: Scott Feldman, Jiri Pirko, Thomas Graf, John Fastabend, Jamal Hadi Salim, Andy Gospodarek, Florian Fainelli, Roopa Prabhu 2) Start making the networking operate on IOV iterators instead of modifying iov objects in-situ during transfers. Thanks to Al Viro and Herbert Xu. 3) A set of new netlink interfaces for the TIPC stack, from Richard Alpe. 4) Remove unnecessary looping during ipv6 routing lookups, from Martin KaFai Lau. 5) Add PAUSE frame generation support to gianfar driver, from Matei Pavaluca. 6) Allow for larger reordering levels in TCP, which are easily achievable in the real world right now, from Eric Dumazet. 7) Add a variable of napi_schedule that doesn't need to disable cpu interrupts, from Eric Dumazet. 8) Use a doubly linked list to optimize neigh_parms_release(), from Nicolas Dichtel. 9) Various enhancements to the kernel BPF verifier, and allow eBPF programs to actually be attached to sockets. From Alexei Starovoitov. 10) Support TSO/LSO in sunvnet driver, from David L Stevens. 11) Allow controlling ECN usage via routing metrics, from Florian Westphal. 12) Remote checksum offload, from Tom Herbert. 13) Add split-header receive, BQL, and xmit_more support to amd-xgbe driver, from Thomas Lendacky. 14) Add MPLS support to openvswitch, from Simon Horman. 15) Support wildcard tunnel endpoints in ipv6 tunnels, from Steffen Klassert. 16) Do gro flushes on a per-device basis using a timer, from Eric Dumazet. This tries to resolve the conflicting goals between the desired handling of bulk vs. RPC-like traffic. 17) Allow userspace to ask for the CPU upon what a packet was received/steered, via SO_INCOMING_CPU. From Eric Dumazet. 18) Limit GSO packets to half the current congestion window, from Eric Dumazet. 19) Add a generic helper so that all drivers set their RSS keys in a consistent way, from Eric Dumazet. 20) Add xmit_more support to enic driver, from Govindarajulu Varadarajan. 21) Add VLAN packet scheduler action, from Jiri Pirko. 22) Support configurable RSS hash functions via ethtool, from Eyal Perry. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1820 commits) Fix race condition between vxlan_sock_add and vxlan_sock_release net/macb: fix compilation warning for print_hex_dump() called with skb->mac_header net/mlx4: Add support for A0 steering net/mlx4: Refactor QUERY_PORT net/mlx4_core: Add explicit error message when rule doesn't meet configuration net/mlx4: Add A0 hybrid steering net/mlx4: Add mlx4_bitmap zone allocator net/mlx4: Add a check if there are too many reserved QPs net/mlx4: Change QP allocation scheme net/mlx4_core: Use tasklet for user-space CQ completion events net/mlx4_core: Mask out host side virtualization features for guests net/mlx4_en: Set csum level for encapsulated packets be2net: Export tunnel offloads only when a VxLAN tunnel is created gianfar: Fix dma check map error when DMA_API_DEBUG is enabled cxgb4/csiostor: Don't use MASTER_MUST for fw_hello call net: fec: only enable mdio interrupt before phy device link up net: fec: clear all interrupt events to support i.MX6SX net: fec: reset fep link status in suspend function net: sock: fix access via invalid file descriptor net: introduce helper macro for_each_cmsghdr ...

Pull ARM SoC driver updates from Arnd Bergmann: "These are changes for drivers that are intimately tied to some SoC and for some reason could not get merged through the respective subsystem maintainer tree. The largest single change here this time around is the Tegra iommu/memory controller driver, which gets updated to the new iommu DT binding. More drivers like this are likely to follow for the following merge window, but we should be able to do those through the iommu maintainer. Other notable changes are: - reset controller drivers from the reset maintainer (socfpga, sti, berlin) - fixes for the keystone navigator driver merged last time - at91 rtc driver changes related to the at91 cleanups - ARM perf driver changes from Will Deacon - updates for the brcmstb_gisb driver" * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (53 commits) clocksource: arch_timer: Allow the device tree to specify uninitialized timer registers clocksource: arch_timer: Fix code to use physical timers when requested memory: Add NVIDIA Tegra memory controller support bus: brcmstb_gisb: Add register offset tables for older chips bus: brcmstb_gisb: Look up register offsets in a table bus: brcmstb_gisb: Introduce wrapper functions for MMIO accesses bus: brcmstb_gisb: Make the driver buildable on MIPS of: Add NVIDIA Tegra memory controller binding ARM: tegra: Move AHB Kconfig to drivers/amba amba: Add Kconfig file clk: tegra: Implement memory-controller clock serial: samsung: Fix serial config dependencies for exynos7 bus: brcmstb_gisb: resolve section mismatch ARM: common: edma: edma_pm_resume may be unused ARM: common: edma: add suspend resume hook powerpc/iommu: Rename iommu_[un]map_sg functions rtc: at91sam9: add DT bindings documentation rtc: at91sam9: use clk API instead of relying on AT91_SLOW_CLOCK ARM: at91: add clk_lookup entry for RTT devices rtc: at91sam9: rework the Kconfig description ...

bus: mvebu-mbus: suspend/resume support

2014-11-30T16:40:10Z

This commit extends the mvebu-mbus driver to provide suspend/resume support. Since mvebu-mbus is not a platform_driver, the syscore_ops mechanism is used to get ->suspend() and ->resume() hooks called into the driver. In those hooks, we save and restore the MBus windows state, to make sure after resume all Mbus windows are properly restored. Note that while the state of some windows could be gathered by looking again at the Device Tree (for statically described windows), it is not the case of dynamically described windows such as the PCIe memory and I/O windows. Therefore, we take the simple approach of saving and restoring the registers for all MBus windows. In addition, the commit extends the Device Tree binding of the MBus controller, to control the MBus bridge registers (which define which parts of the physical address space is routed to MBus windows vs. normal RAM memory). Those registers must be saved and restored during suspend/resume. The Device Tree binding extension is made is a backward compatible fashion, but of course, suspend/resume will not work without the Device Tree update.
