2018-09-13net: dsa: Add Lantiq / Intel DSA driver for vrx200Hauke Mehrtens4-0/+1331
This adds the DSA driver for the GSWIP Switch found in the VRX200 SoC. This switch is integrated in the DSL SoC, this SoC uses a GSWIP version 2.1, there are other SoCs using different versions of this IP block, but this driver was only tested with the version found in the VRX200. Currently only the basic features are implemented which will forward all packages to the CPU and let the CPU do the forwarding. The hardware also support Layer 2 offloading which is not yet implemented in this driver. The GPHY FW loaded is now done by this driver and not any more by the separate driver in drivers/soc/lantiq/gphy.c, I will remove this driver is a separate patch. to make use of the GPHY this switch driver is needed anyway. Other SoCs have more embedded GPHYs so this driver should support a variable number of GPHYs. After the firmware was loaded the GPHY can be probed on the MDIO bus and it behaves like an external GPHY, without the firmware it can not be probed on the MDIO bus. The clock names in the sysctrl.c file have to be changed because the clocks are now used by a different driver. This should be cleaned up and a real common clock driver should provide the clocks instead. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-13net: lantiq: Add Lantiq / Intel VRX200 Ethernet driverHauke Mehrtens3-0/+572
This drives the PMAC between the GSWIP Switch and the CPU in the VRX200 SoC. This is currently only the very basic version of the Ethernet driver. When the DMA channel is activated we receive some packets which were send to the SoC while it was still in U-Boot, these packets have the wrong header. Resetting the IP cores did not work so we read out the extra packets at the beginning and discard them. This also adapts the clock code in sysctrl.c to use the default name of the device node so that the driver gets the correct clock. sysctrl.c should be replaced with a proper common clock driver later.

2018-09-13MIPS: lantiq: Do not enable IRQs in dma openHauke Mehrtens1-0/+1
When a DMA channel is opened the IRQ should not get activated automatically, this allows it to pull data out manually without the help of interrupts. This is needed for a workaround in the vrx200 Ethernet driver. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Acked-by: Paul Burton <paul.burton@mips.com> Signed-off-by: David S.

After system suspend, sometimes the r8169 doesn't work when ethernet cable gets pluggued. This issue happens because rtl_reset_work() doesn't get called from rtl8169_runtime_resume(), after system suspend. In rtl_task(), RTL_FLAG_TASK_* only gets cleared if this condition is met: if (!netif_running(dev) || !test_bit(RTL_FLAG_TASK_ENABLED, tp->wk.flags)) ... If RTL_FLAG_TASK_ENABLED was cleared during system suspend while RTL_FLAG_TASK_RESET_PENDING was set, the next rtl_schedule_task() won't schedule task as the flag is still there.

Pull rdma fixes from Jason Gunthorpe: "This fixes one major regression with NFS and mlx4 due to the max_sg rework in this merge window, tidies a few minor error_path regressions, and various small fixes. The HFI1 driver is broken this cycle due to a regression caused by a PCI change, it is looking like Bjorn will merge a fix for this. Also, the lingering ipoib issue I mentioned earlier still remains unfixed. Summary: - Fix possible FD type confusion crash - Fix a user trigger-able crash in cxgb4 - Fix bad handling of IOMMU resources causing user controlled leaking in bnxt - Add missing locking in ipoib to fix a rare 'stuck tx' situation - Add missing locking in cma - Add two missing missing uverbs cleanups on failure paths, regressions from this merge window - Fix a regression from this merge window that caused RDMA NFS to not work with the mlx4 driver due to the max_sg changes" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: RDMA/mlx4: Ensure that maximal send/receive SGE less than supported by HW RDMA/cma: Protect cma dev list with lock RDMA/uverbs: Fix error cleanup path of ib_uverbs_add_one() bnxt_re: Fix couple of memory leaks that could lead to IOMMU call traces IB/ipoib: Avoid a race condition between start_xmit and cm_rep_handler iw_cxgb4: only allow 1 flush on user qps IB/core: Release object lock if destroy failed RDMA/ucma: check fd type in ucma_migrate_id()
