of: unittest: Disable interrupt node tests for old world MAC systems
On systems with OF_IMAP_OLDWORLD_MAC set in of_irq_workarounds, the
devicetree interrupt parsing code is different, causing unit tests of
devicetree interrupt nodes to fail. Due to a bug in unittest code, which
tries to dereference an uninitialized pointer, this results in a crash.

The problem was observed when running a qemu test for the g3beige machine
with devicetree unittests enabled.
Disable interrupt node tests on affected systems to avoid both false
unittest failures and the crash.
With this patch in place, unittest on the affected system passes with
the following message.

of/platform: initialise AMBA default DMA masks
This addresses a v4.19-rc1 regression in the PL111 DRM driver in drivers/gpu/pl111/* The driver uses the CMA KMS helpers and will thus at some point call down to dma_alloc_attrs() to allocate a chunk of contigous DMA memory for the framebuffer. It appears that in v4.18, it was OK that this (and other DMA mastering AMBA devices) left dev->coherent_dma_mask blank (zero). In v4.19-rc1 the WARN_ON_ONCE(dev && !dev->coherent_dma_mask) in dma_alloc_attrs() in include/linux/dma-mapping.h is triggered. The allocation later fails when get_coherent_dma_mask() is called from __dma_alloc() and __dma_alloc() returns NULL: drm-clcd-pl111 dev:20: coherent DMA mask is unset drm-clcd-pl111 dev:20: [drm:drm_fb_helper_fbdev_setup] *ERROR* Failed to set fbdev configuration It turns out that in commit |

of: add helper to lookup compatible child node
Add of_get_compatible_child() helper that can be used to lookup compatible child nodes. Several drivers currently use of_find_compatible_node() to lookup child nodes while failing to notice that the of_find_ functions search the entire tree depth-first (from a given start node) and therefore can match unrelated nodes. The fact that these functions also drop a reference to the node they start searching from (e.g. the parent node) is typically also overlooked, something which can lead to use-after-free bugs.

OF: Don't set default coherent DMA mask
Now that we can track upstream DMA constraints properly with bus_dma_mask instead of trying (and failing) to maintain it in coherent_dma_mask, it doesn't make much sense for the firmware code to be touching the latter at all. It's merely papering over bugs wherein a driver has failed to call dma_set_coherent_mask() *and* the bus code has not initialised any default value. We don't really want to encourage more drivers coercing dma_mask so we'll continue to fix that up if necessary, but add a warning to help flush out any such buggy bus code that remains.

of: mdio: Support fixed links in of_phy_get_and_connect()
By a simple extension of of_phy_get_and_connect() drivers
that have a fixed link on e.g. RGMII can support also
fixed links, so in addition to:
ethernet-port {
phy-mode = "rgmii";
phy-handle = <&foo>;
};
This setup with a fixed-link node and no phy-handle will
now also work just fine:
ethernet-port {
phy-mode = "rgmii";
fixed-link {
speed = <1000>;
full-duplex;
pause;
};
};
This is very helpful for connecting random ethernet ports
to e.g. DSA switches that typically reside on fixed links.
The phy-mode is still there as the fixes link in this case
is still an RGMII link.
Tested on the Cortina Gemini driver with the Vitesse DSA
router chip on a fixed 1Gbit link.

Merge tag 'overflow-v4.18-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull more overflow updates from Kees Cook:
"The rest of the overflow changes for v4.18-rc1.
This includes the explicit overflow fixes from Silvio, further
struct_size() conversions from Matthew, and a bug fix from Dan.
But the bulk of it is the treewide conversions to use either the
2-factor argument allocators (e.g. kmalloc(a * b, ...) into
kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
b) into vmalloc(array_size(a, b)).
Coccinelle was fighting me on several fronts, so I've done a bunch of
manual whitespace updates in the patches as well.
Summary:
- Error path bug fix for overflow tests (Dan)
- Additional struct_size() conversions (Matthew, Kees)
- Explicitly reported overflow fixes (Silvio, Kees)
- Add missing kvcalloc() function (Kees)
- Treewide conversions of allocators to use either 2-factor argument
variant when available, or array_size() and array3_size() as needed
(Kees)"

treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:
kzalloc(a * b, gfp)
with:
kcalloc(a * b, gfp)
as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:

ARM: SoC: late updates
This is a branch with a few merge requests that either came in late, or took a while longer for us to review and merge than usual and thus cut it a bit close to the merge window. We stage them in a separate branch and if things look good, we still send them up -- and that's the case here. This is mostly DT additions for Renesas platforms, adding IP block descriptions for existing and new SoCs. There are also some driver updates for Qualcomm platforms for SMEM/QMI and GENI, which is their generalized serial protocol interface. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlsfCVIPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3KOcP/3O2+igstXt5rhemITdyi8rHkrIHPgetf25e ISBQzYrQOHV21SqT4le/Gk2CCQ6iX5Nv2DYoIrCzFWi/4DoDxXvryczQLla02Nru i8fcuxae7aFGW7/97G1+cATGPwuBLPiKXs6Wj01sKHeLBja5Det7eoXuHag7Y/Lo 4ls9wNZybMdlCcGm6+ULdj+XUdRyYUhOQQYvnPm2Q8hEkM+AiwLOBJTFwef9P5ad mX37kPDfwCxYwQXgZB1RkK/oJu0G2mTZXmGH5o+s+9yAyAupCQhmHGOrt3mlOf7j tLRlSgarJlO/QGIpJmDuCcxt3msD3OMd2dPbdgwojdpvycOU8EVWYLmCRpyIWQXv DCv9A9Gp4KlJnwxheVegBtilRA1aKsGuarWq6yeyOFt8N23Bgg/IjYKI9JF5+hPD M4q1oVAbUlfWb79rEc+TB0d7euREBkNn4TzzKMSOyP3eGUrXR0WUlq2A2VLxgIJo cx/ufY7CwvRgV+VxfhRbca+FmwDnu7uqzwLe73Ys2hnsuv8hXEtc+vSybqKqxVeU nHpWAqwaWhijlJiGq722vPo8avrLwjsxRwimogvijtesz9ZlTqrGtjkg61+eN2h8 eeuyRAsMUfVRiKuL3W+q4s0rzIauormnKsvRScKVyNFuiJfrfYb1odLoDGaOV/9G dQ7hA7TW =RUL0 -----END PGP SIGNATURE----- Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC late updates from Olof Johansson: "This is a branch with a few merge requests that either came in late, or took a while longer for us to review and merge than usual and thus cut it a bit close to the merge window.

dma-mapping updates for 4.18:
- replaceme the force_dma flag with a dma_configure bus method.
(Nipun Gupta, although one patch is іncorrectly attributed to me
due to a git rebase bug)
- use GFP_DMA32 more agressively in dma-direct. (Takashi Iwai)
- remove PCI_DMA_BUS_IS_PHYS and rely on the dma-mapping API to do the
right thing for bounce buffering.
- move dma-debug initialization to common code, and apply a few cleanups
to the dma-debug code.
- cleanup the Kconfig mess around swiotlb selection
- swiotlb comment fixup (Yisheng Xie)
- a trivial swiotlb fix. (Dan Carpenter)
- support swiotlb on RISC-V. (based on a patch from Palmer Dabbelt)
- add a new generic dma-noncoherent dma_map_ops implementation and use
it for arc, c6x and nds32.
- improve scatterlist validity checking in dma-debug. (Robin Murphy)
- add a struct device quirk to limit the dma-mask to 32-bit due to
bridge/system issues, and switch x86 to use it instead of a local
hack for VIA bridges.
- handle devices without a dma_mask more gracefully in the dma-direct
code.

Merge tag 'dma-mapping-4.18' of git://git.infradead.org/users/hch/dma-mapping
Pull dma-mapping updates from Christoph Hellwig:
- replace the force_dma flag with a dma_configure bus method. (Nipun
Gupta, although one patch is іncorrectly attributed to me due to a
git rebase bug)
- use GFP_DMA32 more agressively in dma-direct. (Takashi Iwai)
- remove PCI_DMA_BUS_IS_PHYS and rely on the dma-mapping API to do the
right thing for bounce buffering.
- move dma-debug initialization to common code, and apply a few
cleanups to the dma-debug code.
- cleanup the Kconfig mess around swiotlb selection
- swiotlb comment fixup (Yisheng Xie)
- a trivial swiotlb fix. (Dan Carpenter)
- support swiotlb on RISC-V. (based on a patch from Palmer Dabbelt)
- add a new generic dma-noncoherent dma_map_ops implementation and use
it for arc, c6x and nds32.
- improve scatterlist validity checking in dma-debug. (Robin Murphy)
- add a struct device quirk to limit the dma-mask to 32-bit due to
bridge/system issues, and switch x86 to use it instead of a local
hack for VIA bridges.
- handle devices without a dma_mask more gracefully in the dma-direct
code.

of: platform: stop accessing invalid dev in of_platform_device_destroy
Immediately after the platform_device_unregister() the device will be cleaned up. Accessing the freed pointer immediately after that will crash the system. Found this bug when kernel is built with CONFIG_PAGE_POISONING and testing loading/unloading audio drivers in a loop on Qcom platforms. Fix this by moving of_node_clear_flag() just before the unregister calls. Below is the crash trace: Unable to handle kernel paging request at virtual address 6b6b6b6b6b6c03 Mem abort info: ESR = 0x96000021 Exception class = DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 Data abort info: ISV = 0, ISS = 0x00000021 CM = 0, WnR = 0 [006b6b6b6b6b6c03] address between user and kernel address ranges Internal error: Oops: 96000021 [#1] PREEMPT SMP Modules linked in: CPU: 2 PID: 1784 Comm: sh Tainted: G W 4.17.0-rc7-02230-ge3a63a7ef641-dirty #204 Hardware name: Qualcomm Technologies, Inc.

Command DB is a simple database in the shared memory of QCOM SoCs, that provides information regarding shared resources. Some shared resources in the SoC have properties that are probed dynamically at boot by the remote processor. The information pertaining to the SoC and the platform are made available in the shared memory. Drivers can query this information using predefined strings.

of/numa: drop export of of_node_to_nid
The "generic" implementation of of_node_to_nid is only used by arm64 and only in built-in code, so remove its export. Any device with a struct device should be able to use dev_to_node() instead. Also, exporting of_node_to_nid doesn't actually work if we build a module on an arch that doesn't select OF_NUMA nor provide its own of_node_to_nid implementation.

seq_put_decimal_ull_w(m, str, val, width) prints a decimal number with a

It is equivalent of seq_printf(m, "%s%*d", str, width, val), but it
works much faster.

kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers
GNU Make automatically deletes intermediate files that are updated
in a chain of pattern rules.
Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts
Example 2) %.o <- %.c <- %.c_shipped
A couple of makefiles mark such targets as .PRECIOUS to prevent Make
from deleting them, but the correct way is to use .SECONDARY.
.SECONDARY
Prerequisites of this special target are treated as intermediate
files but are never automatically deleted.
.PRECIOUS
When make is interrupted during execution, it may delete the target
file it is updating if the file was modified since make started.
If you mark the file as precious, make will never delete the file
if interrupted.
Both can avoid deletion of intermediate files, but the difference is
the behavior when Make is interrupted; .SECONDARY deletes the target,
but .PRECIOUS does not.
The use of .PRECIOUS is relatively rare since we do not want to keep
partially constructed (possibly corrupted) targets.
Another difference is that .PRECIOUS works with pattern rules whereas
.SECONDARY does not.
.PRECIOUS: $(obj)/%.lex.c
works, but
.SECONDARY: $(obj)/%.lex.c
has no effect. However, for the reason above, I do not want to use
.PRECIOUS which could cause obscure build breakage.
The targets specified as .SECONDARY must be explicit. $(targets)
contains all targets that need to include .*.cmd files. So, the
intermediates you want to keep are mostly in there. Therefore, mark
$(targets) as .SECONDARY. It means primary targets are also marked
as .SECONDARY, but I do not see any drawback for this.
I replaced some .SECONDARY / .PRECIOUS markers with 'targets'. This
will make Kbuild search for non-existing .*.cmd files, but this is
not a noticeable performance issue.

kbuild: add %.dtb.S and %.dtb to 'targets' automatically
Another common pattern that consists of chained commands is to compile a DTB as binary data into the kernel image or a module. It is used in several places in the source tree. Support it in the core Makefile. $(call if_changed,dt_S_dtb) is more suitable than $(call cmd,dt_S_dtb) in case cmd_dt_S_dtb is changed in the future.

of: Add missing I/O range exception for indirect-IO devices
There are some special ISA/LPC devices that work on a specific I/O range where it is not correct to specify a 'ranges' property in the DTS parent node as CPU addresses translated from DTS node are only for memory space on some architectures, such as ARM64. Without the parent 'ranges' property, of_translate_address() returns an error. Here we add special handling for this case. During the OF address translation, some checking will be performed to identify whether the device node is registered as indirect-IO. If it is, the I/O translation will be done in a different way from that one of PCI MMIO. In this way, the I/O 'reg' property of the special ISA/LPC devices will be parsed correctly.

of_net: Implement of_get_nvmem_mac_address helper
It's common practice to store MAC addresses for network interfaces into nvmem devices. However the code to actually do this in the kernel lacks, so this patch adds of_get_nvmem_mac_address() for drivers to obtain the address from an nvmem cell provider. This is particulary useful on devices where the ethernet interface cannot be configured by the bootloader, for example because it's in an FPGA.

This moves the declaration into the #ifdef section.
