of_mdio: Abstract a general interface for phy connect
Abstract a general interface "of_phy_get_and_connect" for PHY connect. User will have no bother with getting "phy-mode" and "phy-handle" any more.

of_mdio: select fixed phy support unconditionally
Calling the fixed-phy functions when CONFIG_FIXED_PHY=m as a previous
change tried cannot work if the caller is in built-in code:
drivers/of/built-in.o: In function `of_phy_register_fixed_link':
of_reserved_mem.c:(.text+0x85e0): undefined reference to `fixed_phy_register'
Making of_mdio depend on 'FIXED_PHY || !FIXED_PHY' would solve this
dependency by enforcing that OF_MDIO itself becomes a loadable module
when FIXED_PHY=y, but that creates a different dependency as it
breaks any built-in ethernet driver that uses of_mdio.
Making FIXED_PHY a bool option also cannot work, since it depends on
PHYLIB, which again is tristate.
This version now uses 'select FIXED_PHY' to ensure that the fixed-phy
portion of of_mdio is not optional. The main downside of this is
a small increase in code size for cases that do not need fixed phy
support, but it should avoid all of the link-time problems.

of_mdio: Enable fixed PHY support if driver is a module
The fixed_phy driver doesn't have to be built-in, and it's important that of_mdio supports it even if it's a module. Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

drivers/of: Fix depth for sub-tree blob in unflatten_dt_nodes()
The function is unflattening device sub-tree blob if @dad passed to
the function is valid. Currently, this functionality is used by PPC
PowerNV PCI hotplug driver only. There are possibly multiple nodes
in the first level of depth, fdt_next_node() bails immediately when
@depth becomes negative before the second device node can be probed
successfully. It leads to the device nodes except the first one won't
be unflattened successfully.
This fixes the issue by setting the initial depth (@inital_depth) to
1 when this function is called to unflatten device sub-tree blob. No
logic changes when this function is used to unflatten non-sub-tree
blob.

of: silence warnings due to max() usage
pageblock_order can be (at least) an unsigned int or an unsigned long

of: irq: fix of_irq_get[_byname]() kernel-doc
The kernel-doc for the of_irq_get[_byname]() is clearly inadequate in describing the return values -- of_irq_get_byname() is documented better than of_irq_get() but it still doesn't mention that 0 is returned iff irq_create_of_mapping() fails (it doesn't return an error code in this case). Document all possible return value variants, making the writing of the word "IRQ" consistent, while at it... Fixes: |

drivers/of: Fix build warning in populate_node()
Function populate_node() is used to unflatten FDT blob to device
tree. It supports maximal 64 level of device nodes. There is one
array @fpsizes[64] tracking the full name length of last unflattened
device node in the corresponding level (index of element in the
array - 1). Build warning is seen with CONFIG_FRAME_WARN=1024 like
below on ARM64 as Geert reported. The issue can be reproduced on
PPC64 as well.
$ make drivers/of/fdt.o
drivers/of/fdt.c:443:1: warning: the frame size of 1136 bytes is \
larger than 1024 bytes [-Wframe-larger-than=]
This changes the data type of @fpsizes[i] from "unsigned long" to
"unsigned int" to avoid the build warning. The return value type
of populate_node() and its @fpsize argument is adjusted accordingly.
With this applied, 256 bytes saved from the stack frame on ARM64 and
PPC64 platforms and the above warning isn't seen.

drivers/of: Fix depth when unflattening devicetree
When the implementation for unflatten_dt_node() changed from being
recursive to being non-recursive, it had a side effect of increasing the
depth passed to fdt_next_node() by 1. This is fine most of the time, but
it seems that when the end of the dtb is being parsed, it will cause the
FDT_END condition in fdt_next_node() to return a different value
(returning nextoffset instead of -FDT_ERR_NOTFOUND). This ends up passing
an FDT_ERR_TRUNCATED error back to the unflatten_dt_node() which then
sees that and complains "Error -8 processing FDT" causing boot to fail.
This patch simply avoids incrementing depth and uses modified accesses
for local array indices so that the depth is the same as it was before
the change as far as fdt_next_node() is concerned.
This problem was discovered trying to boot Tegra210-Smaug platforms.

drivers/of: Avoid recursively calling unflatten_dt_node()
In current implementation, unflatten_dt_node() is called recursively to unflatten device nodes in FDT blob. It's stress to limited stack capacity, especially to adopt the function to unflatten device sub-tree that possibly has multiple root nodes. In that case, we runs out of stack and the system can't boot up successfully. In order to reuse the function to unflatten device sub-tree, this avoids calling the function recursively, meaning the device nodes are unflattened in one call on unflatten_dt_node(): two arrays are introduced to track the parent path size and the device node of current level of depth, which will be used by the device node on next level of depth to be unflattened. All device nodes in more than 64 level of depth are dropped and hopefully, the system can boot up successfully with the partial device-tree. Also, the parameter "poffset" and "fpsize" are unused and dropped and the parameter "dryrun" is figured out from "mem == NULL". Besides, the return value of the function is changed to indicate the size of memory consumed by the unflatten device tree or error code.

drivers/of: Split unflatten_dt_node()
The function unflatten_dt_node() is called recursively to unflatten device nodes and properties in the FDT blob. It looks complicated and hard to be understood. This splits the function into 3 functions: populate_properties(), populate_node() and unflatten_dt_node(). populate_properties(), which is called by populate_node(), creates properties for the indicated device node. The later one creates the device nodes from FDT blob. populate_node() gets the offset in FDT blob for next device nodes and then calls populate_node(). No logical changes introduced.

drivers/of: Add check for null property in of_remove_property()
The validity of the property input argument to of_remove_property() is never checked within the function and thus it is possible to pass a null value. It happens that this will be picked up in __of_remove_property() as no matching property of the device node will be found and thus an error will be returned, however once again there is no explicit check for a null value. By the time this is detected 2 locks have already been acquired which is completely unnecessary if the property to remove is null. Add an explicit check in the function of_remove_property() for a null property value and return -ENODEV in this case, this is consistent with what the previous return value would have been when the null value was not detected and passed to __of_remove_property(). By moving an explicit check for the property paramenter into the of_remove_property() function, this will remove the need to perform this check in calling code before invocation of the of_remove_property() function.

of: of_mdio: Check if MDIO bus controller is available
Add a check whether the 'struct device_node' pointer passed to of_mdiobus_register() is an available (aka enabled) node in the Device Tree. Rationale for doing this are cases where an Ethernet MAC provides a MDIO bus controller and node, and an additional Ethernet MAC might be connecting its PHY/switches to that first MDIO bus controller, while still embedding one internally which is therefore marked as "disabled". Instead of sprinkling checks like these in callers of of_mdiobus_register(), do this in a central location.

The of_count_phandle_with_args() function is not converted, because the macro hides the return value of of_phandle_iterator_init(), which is needed in there.

of: Remove counting special case from __of_parse_phandle_with_args()
The index = -1 case in __of_parse_phandle_with_args() is used to just return the number of phandles. That special case needs extra handling, so move it to the place where it is needed: of_count_phandle_with_args(). This allows to further simplify __of_parse_phandle_with_args() later on.

of: mtd: prepare helper reading NAND ECC algo from DT
NAND subsystem is being slightly reworked to store ECC details in separated fields. In future we'll want to add support for more DT properties as specifying every possible setup with a single "nand-ecc-mode" is a pretty bad idea. To allow this let's add a helper that will support something like "nand-ecc-algo" in future. Right now we use it for keeping backward compatibility.

of/platform: Allow secondary compatible match in of_dev_lookup
We currently try to match of_dev_auxdata based on compatible, IO address, and device name. But in some cases we have multiple instances of drivers that can use the same auxdata. Let's add an additional secondary lookup for generic compatible match for auxdata if no device specific match is found. This does not change the existing matching, and still allows adding device specific auxdata. This simplifies things as specifying the IO address and device name is prone errors as it requires maintaining an in kernel database for each SoC. To specify a generic match, all that is needed is to add a OF_DEV_AUXDATA entry with no device instance specified: OF_DEV_AUXDATA("pinctrl-single", 0, NULL, &pcs_pdata), As the auxdata is already initialized only for the booted SoC, there's not much of a chance of getting things wrong. Let's also fix two checkpatch warnings while at it to add a space before parenthesis in the for loop, and remove a comparison to NULL by using !auxdata->compatible.

The muxing can be done using a BPF program which hashes the incoming packet. From Craig Gallek. 5) Add a multiplexer for TCP streams, to provide a messaged based interface. BPF programs can be used to determine the message boundaries. From Tom Herbert. 6) Add 802.1AE MACSEC support, from Sabrina Dubroca. 7) Avoid factorial complexity when taking down an inetdev interface with lots of configured addresses. We were doing things like traversing the entire address less for each address removed, and flushing the entire netfilter conntrack table for every address as well. 8) Add and use SKB bulk free infrastructure, from Jesper Brouer. 9) Allow offloading u32 classifiers to hardware, and implement for ixgbe, from John Fastabend. 10) Allow configuring IRQ coalescing parameters on a per-queue basis, from Kan Liang. 11) Extend ethtool so that larger link mode masks can be supported.

arm64 updates for 4.6:
- Initial page table creation reworked to avoid breaking large block mappings (huge pages) into smaller ones. The ARM architecture requires break-before-make in such cases to avoid TLB conflicts but that's not always possible on live page tables - Kernel virtual memory layout: the kernel image is no longer linked to the bottom of the linear mapping (PAGE_OFFSET) but at the bottom of the vmalloc space, allowing the kernel to be loaded (nearly) anywhere in physical RAM - Kernel ASLR: position independent kernel Image and modules being randomly mapped in the vmalloc space with the randomness is provided by UEFI (efi_get_random_bytes() patches merged via the arm64 tree, acked by Matt Fleming) - Implement relative exception tables for arm64, required by KASLR (initial code for ARCH_HAS_RELATIVE_EXTABLE added to lib/extable.c but actual x86 conversion to deferred to 4.7 because of the merge dependencies) - Support for the User Access Override feature of ARMv8.2: this allows uaccess functions (get_user etc.) to be implemented using LDTR/STTR instructions. Such instructions, when run by the kernel, perform unprivileged accesses adding an extra level of protection. The set_fs() macro is used to "upgrade" such instruction to privileged accesses via the UAO bit - Half-precision floating point support (part of ARMv8.2) - Optimisations for CPUs with or without a hardware prefetcher (using run-time code patching) - copy_page performance improvement to deal with 128 bytes at a time - Sanity checks on the CPU capabilities (via CPUID) to prevent incompatible secondary CPUs from being brought up (e.g. weird big.LITTLE configurations) - valid_user_regs() reworked for better sanity check of the sigcontext information (restored pstate information) - ACPI parking protocol implementation - CONFIG_DEBUG_RODATA enabled by default - VDSO code marked as read-only - DEBUG_PAGEALLOC support - ARCH_HAS_UBSAN_SANITIZE_ALL enabled - Erratum workaround Cavium ThunderX SoC - set_pte_at() fix for PROT_NONE mappings - Code clean-ups -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJW6u95AAoJEGvWsS0AyF7xMyoP/3x2O6bgreSQ84BdO4JChN4+ RQ9OVdX8u2ItO9sgaCY2AA6KoiBuEjGmPl/XRuK0I7DpODTtRjEXQHuNNhz8AelC hn4AEVqamY6Z5BzHFIjs8G9ydEbq+OXcKWEdwSsBhP/cMvI7ss3dps1f5iNPT5Vv 50E/kUz+aWYy7pKlB18VDV7TUOA3SuYuGknWV8+bOY5uPb8hNT3Y3fHOg/EuNNN3 DIuYH1V7XQkXtF+oNVIGxzzJCXULBE7egMcWAm1ydSOHK0JwkZAiL7OhI7ceVD0x YlDxBnqmi4cgzfBzTxITAhn3OParwN6udQprdF1WGtFF6fuY2eRDSH/L/iZoE4DY OulL951OsBtF8YC3+RKLk908/0bA2Uw8ftjCOFJTYbSnZBj1gWK41VkCYMEXiHQk EaN8+2Iw206iYIoyvdjGCLw7Y0oakDoVD9vmv12SOaHeQljTkjoN8oIlfjjKTeP7 3AXj5v9BDMDVh40nkVayysRNvqe48Kwt9Wn0rhVTLxwdJEiFG/OIU6HLuTkretdN dcCNFSQrRieSFHpBK9G0vKIpIss1ZwLm8gjocVXH7VK4Mo/TNQe4p2/wAF29mq4r xu1UiXmtU3uWxiqZnt72LOYFCarQ0sFA5+pMEvF5W+NrVB0wGpXhcwm+pGsIi4IM LepccTgykiUBqW5TRzPz =/oS+ -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: "Here are the main arm64 updates for 4.6.
