2014-07-18ARM: i.MX: Remove Freescale i.MX27 IP Camera board supportAlexander Shiyan
The board has no insufficient support to be fully functional and seems has no users. This patch removes support for this board. However, the support may be added in the future by using the devicetree. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
2014-07-18ARM: imx5: drop option MACH_IMX51_DTShawn Guo
Since i.MX51 becomes DT only now, we can drop option MACH_IMX51_DT and just use SOC_IMX51 instead. While at it, rename imx51-dt.c to mach-imx51.c to align with the name schema of other IMX DT only platforms. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
2014-07-18ARM: imx5: move SOC_IMX5 and SOC_IMX51 into 'Device tree only'Shawn Guo
After moving SOC_IMX51 support over to device tree, all i.MX5 support becomes device tree only now. So options SOC_IMX5 and SOC_IMX51 can just be under 'Device tree only'. While at it, 'select ARCH_MXC_IOMUX_V3' is dropped, since it's only needed by non-DT build before. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
2014-07-18ARM: i.MX: Select HAVE_IMX_SRC for i.MX5 globallyAlexander Shiyan
No reason to choose a symbol HAVE_IMX_SRC separately for each supported i.MX5 CPU, this patch selects this symbol globally for i.MX5. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

2014-06-19ARM: l2c: fix dependencies on PL310 errata symbolsRussell King
A number of configurations spit out warnings similar to: warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0) warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0) Clean up the dependencies here: * PL310 symbols should only be selected when CACHE_L2X0 is enabled. * Since the cache-l2x0 code detects PL310 presence at runtime, and we will eventually get rid of CACHE_PL310, surround these errata options with an if CACHE_L2X0 conditional rather than repeating the dependency against each.

2014-06-17ARM: Remove ARCH_HAS_CPUFREQ config optionStephen Boyd
This config exists entirely to hide the cpufreq menu from the kernel configuration unless a platform has selected it. Nothing is actually built if this config is 'Y' and it just leads to more patches that add a select under a platform Kconfig so that some other CPUfreq option can be chosen. Let's remove the option so that we can always enable CPUfreq drivers on ARM platforms.

2014-03-05ARM: mach-imx: Select CONFIG_SRAM at ARCH_MXC levelFabio Estevam
Booting a mx6q system built with multi_v7_defconfig leads to the following error messages on boot: [ 0.037758] imx6q_ocram_suspend_init: ocram pool unavailable! [ 0.037768] imx6_pm_common_init: failed to initialize ocram suspend -19! This happens because CONFIG_SRAM is not selected by default in multi_v7_defconfig. Fix this by selecting CONFIG_SRAM at ARCH_MXC level, so that other SoCs could use the SRAM driver as well. As SRAM automatically selects GENERIC_ALLOCATOR, just drop it from the Kconfig entry.

Doing so will reduce code in ARM core, reduce the architecture dependencies of our timer drivers, and simplify the code because we no longer go through an architecture layer that is essentially a hotplug notifier. * tag 'remove-local-timers' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm: ARM: smp: Remove local timer API clocksource: time-armada-370-xp: Divorce from local timer API clocksource: time-armada-370-xp: Fix sparse warning ARM: msm: Divorce msm_timer from local timer API ARM: PRIMA2: Divorce timer-marco from local timer API ARM: EXYNOS4: Divorce mct from local timer API ARM: OMAP2+: Divorce from local timer API ARM: smp_twd: Divorce smp_twd from local timer API ARM: smp: Remove duplicate dummy timer implementation Resolved a large number of conflicts due to __cpuinit cleanups, etc. Signed-off-by: Olof Johansson <olof@lixom.net>

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...
2013-06-24ARM: smp_twd: Divorce smp_twd from local timer APIStephen Boyd
Separate the smp_twd timers from the local timer API. This will allow us to remove ARM local timer support in the near future and gets us closer to moving this driver to drivers/clocksource.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates (part 3) from Arnd Bergmann: "This is the third and smallest of the SoC specific updates. Changes include: - SMP support for the Xilinx zynq platform - Smaller imx changes - LPAE support for mvebu - Moving the orion5x, kirkwood, dove and mvebu platforms to a common "mbus" driver for their internal devices. It would be good to get feedback on the location of the "mbus" driver. Since this is used on multiple platforms may potentially get shared with other architectures (powerpc and arm64), it was moved to drivers/bus/. We expect other similar drivers to get moved to the same place in order to avoid creating more top-level directories under drivers/ or cluttering up the messy drivers/misc/ even more." * tag 'soc-for-linus-3' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (50 commits) ARM: imx: reset_controller may be disabled ARM: mvebu: Align the internal registers virtual base to support LPAE ARM: mvebu: Limit the DMA zone when LPAE is selected arm: plat-orion: remove addr-map code arm: mach-mv78xx0: convert to use the mvebu-mbus driver arm: mach-orion5x: convert to use mvebu-mbus driver arm: mach-dove: convert to use mvebu-mbus driver arm: mach-kirkwood: convert to use mvebu-mbus driver arm: mach-mvebu: convert to use mvebu-mbus driver ARM i.MX53: set CLK_SET_RATE_PARENT flag on the tve_ext_sel clock ARM i.MX53: tve_di clock is not part of the CCM, but of TVE ARM i.MX53: make tve_ext_sel propagate rate change to PLL ARM i.MX53: Remove unused tve_gate clkdev entry ARM i.MX5: Remove tve_sel clock from i.MX53 clock tree ARM: i.MX5: Add PATA and SRTC clocks ARM: imx: do not bring up unavailable cores ARM: imx: add initial imx6dl support ARM: imx1: mm: add call to mxc_device_init ARM: imx_v4_v5_defconfig: Add CONFIG_GPIO_SYSFS ARM: imx_v6_v7_defconfig: Select CONFIG_PERF_EVENTS ...
