On Pixel 6 (and Pro), a MAX77759 companion PMIC for USB Type-C
applications is used, which contains four functional blocks (at
distinct I2C addresses):
* top (including GPIO & NVMEM)
* charger
* fuel gauge
* TCPCi
This change adds the PMIC and the subnodes for the GPIO expander and
NVMEM, and defines the NVMEM layout.
The NVMEM layout is declared such that it matches downstream's
open-coded configuration [1].
Note:
The pinctrl nodes are kept sorted by the 'samsung,pins' property rather
than node name, as I think that makes it easier to look at and to add
new nodes unambiguously in the future. Its label is prefixed with 'if'
(for interface), because there are three PMICs in total in use on
Pixel 6 (Pro).

Airoha AN7583 SoC have 2 dedicated MDIO bus controller in the SCU
register map. To driver register an MDIO controller based on the DT
reg property and access the register by accessing the parent syscon.
The MDIO bus logic is similar to the MT7530 internal MDIO bus but
deviates of some setting and some HW bug.
On Airoha AN7583 the MDIO clock is set to 25MHz by default and needs to
be correctly setup to 2.5MHz to correctly work (by setting the divisor
to 10x).
There seems to be Hardware bug where AN7583_MII_RWDATA
is not wiped in the context of unconnected PHY and the
previous read value is returned.
Example: (only one PHY on the BUS at 0x1f)
- read at 0x1f report at 0x2 0x7500
- read at 0x0 report 0x7500 on every address
To workaround this, we reset the Mdio BUS at every read
to have consistent values on read operation.

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument. Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.
There is also no real benefit in printing errors on missing syscon
argument, because this is done just too late: runtime check on
static/build-time data. Dtschema and Devicetree bindings offer the
static/build-time check for this already.

Current AMD IOMMU assumes Host Address Translation (HAT) is always
supported, and Linux kernel enables this capability by default. However,
in case of emulated and virtualized IOMMU, this might not be the case.
For example,current QEMU-emulated AMD vIOMMU does not support host
translation for VFIO pass-through device, but the interrupt remapping
support is required for x2APIC (i.e. kvm-msi-ext-dest-id is also not
supported by the guest OS). This would require the guest kernel to boot
with guest kernel option iommu=pt to by-pass the initialization of
host (v1) table.
The AMD I/O Virtualization Technology (IOMMU) Specification Rev 3.10 [1]
introduces a new flag 'HATDis' in the IVHD 11h IOMMU attributes to indicate
that HAT is not supported on a particular IOMMU instance.
Therefore, modifies the AMD IOMMU driver to detect the new HATDis
attributes, and disable host translation and switch to use guest
translation if it is available. Otherwise, the driver will disable DMA
translation.

ptp: Belated spring cleaning of the chardev driver
When looking into supporting auxiliary clocks in the PTP ioctl, the
inpenetrable ptp_ioctl() letter soup bothered me enough to clean it up.
The code (~400 lines!) is really hard to follow due to a gazillion of
local variables, which are only used in certain case scopes, and a
mixture of gotos, breaks and direct error return paths.
Clean it up by splitting out the IOCTL functionality into seperate
functions, which contain only the required local variables and are trivial
to follow. Complete the cleanup by converting the code to lock guards and
get rid of all gotos.
That reduces the code size by 48 lines and also the binary text size is
80 bytes smaller than the current maze.
The series is split up into one patch per IOCTL command group for easy
review.

Continue the ptp_ioctl() cleanup by splitting out the PTP_PIN_GETFUNC ioctl
code into a helper function. Convert to lock guard while at it and remove
the pointless memset of the pd::rsv because nothing uses it.
No functional change intended.

ptp_ioctl() is an inpenetrable letter soup with a gazillion of case (scope)
specific variables defined at the top of the function and pointless breaks
and gotos.
Start cleaning it up by splitting out the PTP_CLOCK_GETCAPS ioctl code into
a helper function. Use a argument pointer with a single sparse compliant
type cast instead of proliferating the type cast all over the place.
No functional change intended.

setup_wait() takes an optional argument and then is called from the top
level of the test script. That confuses shellcheck, which thinks that maybe
the intention is to pass $1 of the script to the function, which is never
the case. To avoid having to annotate every single new test with a SC
disable, split the function in two: one that takes a mandatory argument,
and one that takes no argument at all.
Convert the two existing users of that optional argument, both in Spectrum
resource selftest, to use the new form. Clean up vxlan_bridge_1q_mc_ul.sh
to not pass a now-unused argument.

Merge tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Daniel Borkmann says:
====================
pull-request: bpf-next 2025-06-27
We've added 6 non-merge commits during the last 8 day(s) which contain
a total of 6 files changed, 120 insertions(+), 20 deletions(-).
The main changes are:
1) Fix RCU usage in task_cls_state() for BPF programs using helpers like
bpf_get_cgroup_classid_curr() outside of networking, from Charalampos
Mitrodimas.
2) Fix a sockmap race between map_update and a pending workqueue from
an earlier map_delete freeing the old psock where both pointed to the
same psock->sk, from Jiayuan Chen.
3) Fix a data corruption issue when using bpf_msg_pop_data() in kTLS which
failed to recalculate the ciphertext length, also from Jiayuan Chen.
4) Remove xdp_redirect_map{,_err} trace events since they are unused and
also hide XDP trace events under CONFIG_BPF_SYSCALL, from Steven Rostedt.

Add missing DP PHY status and VCO clock configuration registers to fix
configuring the VCO rate on SM8750. Without proper VCO rate setting, it
works on after-reset half of rate which is not enough for DP over USB to
work as seen on logs:
[drm:msm_dp_ctrl_link_train_1_2] *ERROR* max v_level reached
[drm:msm_dp_ctrl_link_train_1_2] *ERROR* link training #1 on phy 0 failed. ret=-11
