2016-05-12ata: sata_dwc_460ex: use readl/writel_relaxed()Mans Rullgard
Rename the register access macros and use standard _relaxed() ops instead of __raw variants with explicit byte swapping. The original driver used the ppc-specific in/out_le32(). When it was adapted to other systems, these were added to the driver under ifdefs. However, those names are not defined as macros on ppc, so it ended up replacing them there as well with altered semantics. This patch restores the original semantics on ppc and makes the accesses no less strict on other systems. Also fixes too many sparse warnings to count.

2016-05-12PCI, of: Move PCI I/O space management to PCI core codeTomasz Nowicki
No functional changes in this patch. PCI I/O space mapping code does not depend on OF; therefore it can be moved to PCI core code. This way we will be able to use it, e.g., in ACPI PCI code.

2016-05-12PCI: generic, thunder: Use generic ECAM APIJayachandran C
Use functions provided by drivers/pci/ecam.h for mapping the config space in drivers/pci/host/pci-host-common.c, and update its users to use 'struct pci_config_window' and 'struct pci_ecam_ops'. The changes are mostly to use 'struct pci_config_window' in place of 'struct gen_pci'. Some of the fields of gen_pci were only used temporarily and can be eliminated by using local variables or function arguments, these are not carried over to struct pci_config_window. pci-thunder-ecam.c and pci-thunder-pem.c are the only users of the pci_host_common_probe function and the gen_pci structure; these have been updated to use the new API as well. The patch does not introduce any functional changes other than a very minor one: with the new code, on 64-bit platforms, we do just a single ioremap for the whole config space.

This adds support in 2 ndo that allow PF to tweak the VF's view of the link - `ndo_set_vf_link_state' to allow it a view independent of the PF's, and `ndo_set_vf_rate' which would allow the PF to limit the VF speed.

2016-05-12qed: Align TLVsYuval Mintz
As the VF infrastructure is supposed to offer backward/forward compatibility, the various types associated with VF<->PF communication should be aligned across all various platforms that support IOV on our family of adapters. This adds a couple of currently missing values, specifically aligning the enum for the various TLVs possible in the communication between them. It then adds the PF implementation for some of those missing VF requests. This support isn't really necessary for the Linux VF as those VFs aren't requiring it [at least today], but are required by VFs running on other OSes. LRO is an example of one such configuration.

2016-05-12qed: Bulletin and LinkYuval Mintz
Up to this point, VF and PF communication always originates from VF. As a result, VF cannot be notified of any async changes, and specifically cannot be informed of the current link state. This introduces the bulletin board, the mechanism through which the PF is going to communicate async notifications back to the VF. basically, it's a well-defined structure agreed by both PF and VF which the VF would continuously poll and into which the PF would DMA messages when needed. [Bulletin board is actually allocated and communicated in previous patches but never before used] Based on the bulletin infrastructure, the VF can query its link status and receive said async carrier changes.

2016-05-12qed: IOV l2 functionalityYuval Mintz
This adds sufficient changes to allow VFs l2-configuration flows to work. While the fastpath of the VF and the PF are meant to be exactly the same, the configuration of the VF is done by the PF. This diverges all VF-related configuration flows that originate from a VF, making them pass through the VF->PF channel and adding sufficient logic on the PF side to support them.

2016-05-12qed: IOV configure and FLRYuval Mintz
While previous patches have already added the necessary logic to probe VFs as well as enabling them in the HW, this patch adds the ability to support VF FLR & SRIOV disable. It then wraps both flows together into the first IOV callback to be provided to the protocol driver - `configure'. This would later to be used to enable and disable SRIOV in the adapter.

2016-05-12qed: Introduce VFsYuval Mintz
This adds the qed VFs for the first time - The vfs are limited functions, with a very different PCI bar structure [when compared with PFs] to better impose the related security demands associated with them. This patch includes the logic neccesary to allow VFs to successfully probe [without actually adding the ability to enable iov]. This includes diverging all the flows that would occur as part of the pci probe of the driver, preventing VF from accessing registers/memories it can't and instead utilize the VF->PF channel to query the PF for needed information.

2016-05-12qed: Add VF->PF channel infrastructureYuval Mintz
Communication between VF and PF is based on a dedicated HW channel; VF will prepare a messge, and by signaling the HW the PF would get a notification of that message existance. The PF would then copy the message, process it and DMA an answer back to the VF as a response. The messages themselves are TLV-based - allowing easier backward/forward compatibility. This patch adds the infrastructure of the channel on the PF side - starting with the arrival of the notification and ending with DMAing the response back to the VF. It also adds a dummy-response as reference, as it only lays the groundwork of the communication; it doesn't really add support of any actual messages.

2016-05-12qed: Add CONFIG_QED_SRIOVYuval Mintz
Add support for a new Kconfig option for qed* driver which would allow [eventually] the support in VFs. This patch adds the necessary logic in the PF to learn about the possible VFs it will have to support [Based on PCI configuration space and HW], and prepare a database with an entry per-VF as infrastructure for future interaction with said VFs.

2016-05-11bnxt_en: Add workaround to detect bad opaque in rx completion (part 1)Michael Chan
There is a rare hardware bug that can cause a bad opaque value in the RX or TPA completion. When this happens, the hardware may have used the same buffer twice for 2 rx packets. In addition, the driver will also crash later using the bad opaque as the index into the ring. The rx opaque value is predictable and is always monotonically increasing. The workaround is to keep track of the expected next opaque value and compare it with the one returned by hardware during RX and TPA start completions. If they miscompare, we will not process any more RX and TPA completions and exit NAPI. We will then schedule a workqueue to reset the function. This patch adds the logic to keep track of the next rx consumer index. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

CQE compression feature is meant to save PCIe bandwidth by compressing few CQEs into smaller amount of bytes on PCIe. CQE compression can be selectively enabled per CQ. By default is disabled for now and will be enabled later on.

2016-05-11dsa: mv88e6xxx: Handle eeprom-length propertyAndrew Lunn
A switch can export an attached EEPROM using the standard ethtool API. However the switch itself cannot determine the size of the EEPROM, and multiple sizes are allowed. Thus a device tree property is supported to indicate the length of the EEPROM. Parse this property during device probe, and implement a callback function to retrieve it.

2016-05-11dsa: Rename switch chip data to cdAndrew Lunn
The dsa_switch structure contains a dsa_chip_data member called pd. However in the rest of the code, pd is used for dsa_platform_data. This is confusing. Rename it cd, which is already often used in dsa.c and slave.c for this data type. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-11dsa: Remove master_dev from switch structureAndrew Lunn
The switch drivers only use the master_dev member for dev_info() messages. Now that the device is passed to the old style probe, and new style drivers are probed as true linux drivers, this is no longer needed.
