2015-08-25of/address: Don't loop forever in of_find_matching_node_by_address().David Daney1-3/+3
If the internal call to of_address_to_resource() fails, we end up looping forever in of_find_matching_node_by_address(). This can be caused by a defective device tree, or calling with an incorrect matches argument. Fix by calling of_find_matching_node() unconditionally at the end of the loop.

2015-08-25of/platform: add function to populate default busHauke Mehrtens1-0/+9
When a default bus like the simple-bus should be used someone had to call of_platform_populate() with the default match table. This match table was not exported, so it is impossible for code build as a module to use this. Instead of exporting of_default_bus_match_table, add a new function which uses this default match table and populates the bus.

2015-08-24of/fdt: make memblock maximum physical address arch configurableArd Biesheuvel1-5/+7
When parsing the memory nodes to populate the memblock memory table, we check against high and low limits and clip any memory that exceeds either one of them. However, for arm64, the high limit of (phys_addr_t)~0 is not very meaningful, since phys_addr_t is 64 bits (i.e., no limit) but there may be other constraints that limit the memory ranges that we can support. So rename MAX_PHYS_ADDR to MAX_MEMBLOCK_ADDR (for clarity) and only define it if the arch does not supply a definition of its own.

2015-07-22of_mdio: add new DT property 'managed' to specify the PHY management typeStas Sergeev1-2/+17
Currently the PHY management type is selected by the MAC driver arbitrary. The decision is based on the presence of the "fixed-link" node and on a will of the driver's authors. This caused a regression recently, when mvneta driver suddenly started to use the in-band status for auto-negotiation on fixed links. It appears the auto-negotiation may not work when expected by the MAC driver. Sebastien Rannou explains: << Yes, I confirm that my HW does not generate an in-band status. AFAIK, it's a PHY that aggregates 4xSGMIIs to 1xQSGMII ; the MAC side of the PHY (with inband status) is connected to the switch through QSGMII, and in this context we are on the media side of the PHY. >> https://lkml.org/lkml/2015/7/10/206 This patch introduces the new string property 'managed' that allows the user to set the management type explicitly. The supported values are: "auto" - default. Uses either MDIO or nothing, depending on the presence of the fixed-link node "in-band-status" - use in-band status Signed-off-by: Stas Sergeev <stsp@users.sourceforge.net> CC: Rob Herring <robh+dt@kernel.org> CC: Pawel Moll <pawel.moll@arm.com> CC: Mark Rutland <mark.rutland@arm.com> CC: Ian Campbell <ijc+devicetree@hellion.org.uk> CC: Kumar Gala <galak@codeaurora.org> CC: Florian Fainelli <f.fainelli@gmail.com> CC: Grant Likely <grant.likely@linaro.org> CC: devicetree@vger.kernel.org CC: linux-kernel@vger.kernel.org CC: netdev@vger.kernel.org Signed-off-by: David S.

2015-06-30of/irq: Fix pSeries boot failureJeremy Linton1-2/+1
of_irq_parse_raw() needs to return the correct interrupt controller node when an interrupt-map property doesn't exist. It allows of_irq_parse_raw() to return the node pointer of the interrupt controller, rather than the parent bus. This allows ics_rtas_host_match() to detect that the controller is a legacy 8259 and avoid using xics. This avoids an RTAS assertion/crash during early kernel bootstrapping.

This is necessary because the physical address of the FDT, which is needed to perform the reservation, may not be known to the FDT driver core, i.e., it may be mapped outside the linear direct mapping, in which case __pa() returns a bogus value.

Commit 5590f3196b29 ("drivers/core/of: Add symlink to device-tree from devices with an OF node") adds the symlink `of_node` for each device pointing to it's device tree node while creating/initialising it. However the devicetree sysfs is created and setup in of_init which is executed at core_initcall level. For all the devices created before of_init, the following error is thrown: "Error -2(-ENOENT) creating of_node link" Like many other components in driver model, initialize the sysfs support for OF/devicetree from driver_init so that it's ready before any devices are created.

This defines a new compatible option for MFD devices "simple-mfd" that will make the OF core spawn child devices for all subnodes of that MFD device. It is optional but handy for things like syscon and possibly other simpler MFD devices.

All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf. In particular, in the case where an rhashtable user bulk adds a large number of items into an empty table, we expand the table much more sanely. 10) Don't make the tcp_metrics hash table per-namespace, from Eric Biederman. 11) Extend EBPF to access SKB fields, from Alexei Starovoitov. 12) Split out new connection request sockets so that they can be established in the main hash table. Much less false sharing since hash lookups go direct to the request sockets instead of having to go first to the listener then to the request socks hashed underneath.

Now, flaws of I2C controllers can be described and the core will check if the flaws collide with the messages to be sent - wait_for_completion return type cleanup series - new drivers for Digicolor, Netlogic XLP, Ingenic JZ4780 - updates to the I2C slave framework which include API changes. Its only user was updated, too. Documentation was finally added - changed dynamic bus numbering for the DT case. This could change bus numbers for users. However, it fixes a collision where dynamic and static busses request the same id. - driver bugfixes, cleanups" * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (52 commits) i2c: xlp9xx: Driver for Netlogic XLP9XX/5XX I2C controller of: Add vendor prefix 'netlogic' i2c: davinci: use ICPFUNC to toggle I2C as gpio for bus recovery i2c: davinci: use bus recovery infrastructure i2c: change input parameter to i2c_adapter for prepare/unprepare_recovery i2c: i2c-mux-gpio: remove error messages for probe deferrals i2c: jz4780: Add i2c bus controller driver for Ingenic JZ4780 i2c: dln2: set the device tree node of the adapter i2c: davinci: fixup wait_for_completion_timeout handling i2c: mpc: Fix ISR return value i2c: slave-eeprom: add more info when to increase the pointer i2c: slave: add documentation for i2c-slave-eeprom Documentation: i2c: describe the new slave mode i2c: slave: rework the slave API i2c: add support for the Digicolor I2C controller i2c: busses with dynamic ids should start after fixed ids for DT of: base: add function to get highest id of an alias stem i2c: designware: Suppress error message if platform_get_irq() < 0 i2c: mpc: assign the correct prescaler from SVR i2c: img-scb: fixup of wait_for_completion_timeout return handling ...
