2012-10-01dt: introduce of_get_child_by_name to get child node by nameSrinivas Kandagatla
This patch introduces of_get_child_by_name function to get a child node by its name in a given parent node. Without this patch each driver code has to iterate the parent and do a string compare, However having of_get_child_by_name libary function would avoid code duplication, errors and is more convenient.

2012-09-07of: i2c: add support for wakeup-source propertyOlof Johansson
Add support for specifying a generic "wakeup-source" property on i2c clients, which will set the I2C_CLIENT_WAKE flag, thus configuring the device to wake the system from suspend (via IRQ). This obviously doesn't make sense on devices lacking IRQ, but since we still allow that in the i2c_board_info case, I don't see a reason to restrict it here. Note: Since the generic i2c bindings aren't documented in the kernel, I didn't find a good place to add documentation for this binding extension. I still think it makes sense to have a generic property instead of having each device do its own binding for the same.

2012-09-07of/address: Handle #address-cells > 2 speciallyThierry Reding
When a bus specifies #address-cells > 2, of_bus_default_map() now assumes that the mapping isn't for a physical address but rather an identifier that needs to match exactly. This is required by bindings that use multiple cells to translate a resource to the parent bus (device index, type, ...).

Macro for_each_child_of_node() makes it easy to iterate over all of the children for a given device tree node, including those nodes that are marked as unavailable (i.e. status = "disabled"). Introduce for_each_available_child_of_node(), which is like for_each_child_of_node(), but it automatically skips unavailable nodes. This also requires the introduction of helper function of_get_next_available_child(), which returns the next available child node.

2012-08-03of: Allow busses with #size-cells=0Stephen Warren
It's quite legitimate for a DT node to specify #size-cells=0. One example is a node that's used to collect a number of non-memory-mapped devices. In that scenario, there may be multiple child nodes with the same name (type) thus necessitating the use of unit addresses in node names, and reg properties: / { regulators { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <0>; regulator@0 { compatible = "regulator-fixed"; reg = <0>; ... }; regulator@1 { compatible = "regulator-fixed"; reg = <1>; ... }; ... }; }; However, #size-cells=0 prevents translation of reg property values into the parent node's address space. In turn, this triggers the kernel to emit error messages during boot, such as: prom_parse: Bad cell count for /regulators/regulator@0 To prevent printing these error messages for legitimate DT content, a number of changes are made: 1) of_get_address()/of_get_pci_address() are modified only to validate the value of #address-cells, and not #size-cells. 2) of_can_translate_address() is added to indicate whether address translation is possible. 3) of_device_make_bus_id() is modified to name devices based on the translated address only where possible, and otherwise fall back to using the (first cell of the) raw untranslated address. 4) of_device_alloc() is modified to create memory resources for a device only if the address can be translated into the CPU's address space.

Pull networking changes from David S Miller: 1) Remove the ipv4 routing cache. Now lookups go directly into the FIB trie and use prebuilt routes cached there. No more garbage collection, no more rDOS attacks on the routing cache. Instead we now get predictable and consistent performance, no matter what the pattern of traffic we service. This has been almost 2 years in the making. Special thanks to Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who have helped along the way. I'm sure that with a change of this magnitude there will be some kind of fallout, but such things ought the be simple to fix at this point. Luckily I'm not European so I'll be around all of August to fix things :-) The major stages of this work here are each fronted by a forced merge commit whose commit message contains a top-level description of the motivations and implementation issues. 2) Pre-demux of established ipv4 TCP sockets, saves a route demux on input. 3) TCP SYN/ACK performance tweaks from Eric Dumazet. 4) Add namespace support for netfilter L4 conntrack helpers, from Gao Feng. 5) Add config mechanism for Energy Efficient Ethernet to ethtool, from Yuval Mintz. 6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet. 7) Support for connection tracker helpers in userspace, from Pablo Neira Ayuso. 8) Allow userspace driven TX load balancing functions in TEAM driver, from Jiri Pirko. 9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with embedded gotos. 10) TCP Small Queues, essentially minimize the amount of TCP data queued up in the packet scheduler layer. Whereas the existing BQL (Byte Queue Limits) limits the pkt_sched --> netdevice queuing levels, this controls the TCP --> pkt_sched queueing levels. From Eric Dumazet. 11) Reduce the number of get_page/put_page ops done on SKB fragments, from Alexander Duyck. 12) Implement protection against blind resets in TCP (RFC 5961), from Eric Dumazet. 13) Support the client side of TCP Fast Open, basically the ability to send data in the SYN exchange, from Yuchung Cheng. Basically, the sender queues up data with a sendmsg() call using MSG_FASTOPEN, then they do the connect() which emits the queued up fastopen data. 14) Avoid all the problems we get into in TCP when timers or PMTU events hit a locked socket. The TCP Small Queues changes added a tcp_release_cb() that allows us to queue work up to the release_sock() caller, and that's what we use here too. From Eric Dumazet. 15) Zero copy on TX support for TUN driver, from Michael S.

This reverts commit 107a84e61cdd3406c842a0e4be7efffd3a05dba6. Meelis Roos reports a regression since 3.5-rc5 that stops Sun Fire V100 and Sun Netra X1 sparc64 machines from booting, hanging after enabling serial console. He bisected it to commit 107a84e61cdd. Rob Herring explains: "The problem is match combinations of compatible plus name and/or type fail to match correctly. I have a fix for this, but given how late it is for 3.5 I think it is best to revert this for now. There could be other cases that rely on the current although wrong behavior.

2012-07-06of: address: Don't fail a lookup just because a node has no reg propertyLee Jones
Sometimes it doesn't make any sense for a node to have an address. In this case device lookup will always be unsuccessful because we currently assume every node will have a reg property. This patch changes the semantics so that the resource address and the lookup address will only be compared if one exists. Things like AUXDATA() rely on of_dev_lookup to return the lookup entry of a particular device in order to do things like apply platform_data to a device. However, this is currently broken for nodes which do not have a reg property, meaning that platform_data can not be passed in those cases.

2012-06-27netdev/phy/of: Handle IEEE802.3 clause 45 Ethernet PHYs in of_mdiobus_register()David Daney
Define two new "compatible" values for Ethernet PHYs. "ethernet-phy-ieee802.3-c22" and "ethernet-phy-ieee802.3-c45" are used to indicate a PHY uses the corresponding protocol. If a PHY is "compatible" with "ethernet-phy-ieee802.3-c45", we indicate this so that get_phy_device() can properly probe the device. If get_phy_device() fails, it was probably due to failing the probe of the PHY identifier registers. Since we have the device tree telling us the PHY exists, go ahead and add it anyhow with a phy_id of zero. There may be a driver match based on the "compatible" property.

2012-06-27netdev/phy: Handle IEEE802.3 clause 45 Ethernet PHYsDavid Daney
The IEEE802.3 clause 45 MDIO bus protocol allows for directly addressing PHY registers using a 21 bit address, and is used by many 10G Ethernet PHYS. Already existing is the ability of MDIO bus drivers to use clause 45, with the MII_ADDR_C45 flag. Here we add struct phy_c45_device_ids to hold the device identifier registers present in clause 45. struct phy_device gets a couple of new fields: c45_ids to hold the identifiers and is_c45 to signal that it is clause 45. get_phy_device() gets a new parameter is_c45 to indicate that the PHY device should use the clause 45 protocol, and its callers are adjusted to pass false. The follow-on patch to of_mdio.c will pass true where appropriate. EXPORT phy_device_create() so that the follow-on patch to of_mdio.c can use it to create phy devices for PHYs, that have non-standard device identifier registers, based on the device tree bindings.

Among the key features for this patch series is a sizable patchset for Lantiq which among other things introduces support for Lantiq's flagship product, the FALCON SOC. It also means that the opensource developers behind this patchset have overtaken Lantiq's competing inhouse development team that was working behind closed doors.

Pull i2c-embedded changes from Wolfram Sang: "Major changes: - lots of devicetree additions for existing drivers. I tried hard to make sure the bindings are proper. In more complicated cases, I requested acks from people having more experience with them than me. That took a bit of extra time and also some time went into discussions with developers about what bindings are and what not. I have the feeling that the workflow with bindings should be improved to scale better. I will spend some more thought on this... - i2c-muxes are succesfully used meanwhile, so we dropped EXPERIMENTAL for them and renamed the drivers to a standard pattern to match the rest of the subsystem. They can also be used with devicetree now. - ixp2000 was removed since the whole platform goes away. - cleanups (strlcpy instead of strcpy, NULL instead of 0) - The rest is typical driver fixes I assume.

Add of_mdio_find_bus() which allows an mii_bus to be located given its associated the device tree node. This is needed by the follow-on patch to add a driver for MDIO bus multiplexers. The of_mdiobus_register() function is modified so that the device tree node is recorded in the mii_bus. Then we can find it again by iterating over all mdio_bus_class devices. Because the OF device tree has now become an integral part of the kernel, this can live in mdio_bus.c (which contains the needed mdio_bus_class structure) instead of of_mdio.c.

2012-04-22ARM: spear: remove most mach/*.h header contentsArnd Bergmann
The register and irq definitions in mach/*.h for spear3xx and spear6xx are now mostly obsolete, after the platforms have been converted to device tree based probing and the data is now part of the device tree files. The misc_regs.h contents are moved into clock.c because that is the only user, aside from the DMA_CHN_CFG that should eventually get handled differently. Some of the contents of mach/spear.h still remain, because they are used to set up the static map table, timer, uart and auxdata tables, but almost everything got removed. We might remove everything but the map table as the DT conversion completes, but that is not a priority. I've also made sure to make both copies of spear.h more or less identical so we can eventually combine them. The spear3?0.h files were only used by the spear3?0.c files, so I merged the contents in there and removed the bits that were unused. This is something that should still be looked at.

Originally the plan has been to create an all-new irq_domain implementation which addresses some of the powerpc shortcomings such as not handling 1:1 mappings well, but doing that proved to be far more difficult and invasive than generalizing the working code and refactoring it in-place. So, this branch rips out the 'new' irq_domain and replaces it with the modified powerpc version (in a fully bisectable way of course). It converts all users over to the new API and makes irq_domain selectable on any architecture. No architecture is forced to enable irq_domain, but the infrastructure is required for doing OpenFirmware style irq translations. It will even work on SPARC even though SPARC has it's own mechanism for translating irqs at boot time. MIPS, microblaze, embedded x86 and c6x are converted too.
