drm/vc4: Fix missing platform_unregister_drivers() call in vc4_drm_register()
A problem about modprobe vc4 failed is triggered with the following log
given:

 [  420.327987] Error: Driver 'vc4_hvs' is already registered, aborting...
 [  420.333904] failed to register platform driver vc4_hvs_driver [vc4]: -16
 modprobe: ERROR: could not insert 'vc4': Device or resource busy

The reason is that vc4_drm_register() returns platform_driver_register()
directly without checking its return value, if platform_driver_register()
fails, it returns without unregistering all the vc4 drivers, resulting the
vc4 can never be installed later.
A simple call graph is shown as below:

 vc4_drm_register()
   platform_register_drivers() # all vc4 drivers are registered
   platform_driver_register()
     driver_register()
       bus_add_driver()
         priv = kzalloc(...) # OOM happened
   # return without unregister drivers

Fixing this problem by checking the return value of
platform_driver_register() and do platform_unregister_drivers() if
error happened.

1313edfdcd arm64: dts: ti: k3-am625-sk: Add 1.4GHz OPP
The 1.4 GHz OPP requires supported silicon variant (T speed grade) and
also VDD_CORE to be at 0.85V.  All production revisions of the AM625-SK
have both so we can enable the 1.4 GHz OPP for it.  Any other boards
based on this design should verify that they have the right silicon
variant and the right power tree before adding 1.4 GHz support in their
board dts file.

squashfs: enable idmapped mounts
For squashfs all needed functionality for idmapped mounts is already
implemented by the generic handlers in the VFS. Thus, it is sufficient
to just enable the corresponding FS_ALLOW_IDMAP flag to support
idmapped mounts.

We use this for unprivileged (user namespaced) containers based on
squashfs images as rootfs in GyroidOS.

A simple test using the mount-idmapped tool executed as user with
uid=1000 looks as follows:

$ mkdir test
$ echo "test" > test/test_file
$ mksquashfs test/ fs.img
$ sudo mkdir /mnt/test
$ sudo mkdir /mnt/mapped
$ sudo mount fs.img -o loop /mnt/test/
$ sudo ./mount-idmapped --map-mount b:1000:2000:1 /mnt/test/ /mnt/mapped/

$ mount | tail -n2
fs.img on /mnt/test type squashfs (ro,relatime,errors=continue)
fs.img on /mnt/mapped type squashfs (ro,relatime,idmapped,errors=continue)

$ ls -lan /mnt/test/

6973091d1b KVM: s390: pv: don't allow userspace to set the clock under PV
When running under PV, the guest's TOD clock is under control of the
ultravisor and the hypervisor isn't allowed to change it. Hence, don't
allow userspace to change the guest's TOD clock by returning
-EOPNOTSUPP.

When userspace changes the guest's TOD clock, KVM updates its
kvm.arch.epoch field and, in addition, the epoch field in all state
descriptions of all VCPUs.

But, under PV, the ultravisor will ignore the epoch field in the state
description and simply overwrite it on next SIE exit with the actual
guest epoch. This leads to KVM having an incorrect view of the guest's
TOD clock: it has updated its internal kvm.arch.epoch field, but the
ultravisor ignores the field in the state description.

Whenever a guest is now waiting for a clock comparator, KVM will
incorrectly calculate the time when the guest should wake up, possibly
causing the guest to sleep for much longer than expected.

With this change, kvm_s390_set_tod() will now take the kvm->lock to be
able to call kvm_s390_pv_is_protected(). Since kvm_s390_set_tod_clock()
also takes kvm->lock, use __kvm_s390_set_tod_clock() instead.

The function kvm_s390_set_tod_clock is now unused, hence remove it.
Update the documentation to indicate the TOD clock attr calls can now
return -EOPNOTSUPP.

could send port control command to PF driver via mailbox.

The control command only can be set to register in PF,
so add support in PF driver for VF PMD driver control
command when VF PMD driver work with linux PF driver.

Then, no need to add handlers to nic_vf_cmd_msg_handler[],
because the host driver just forwards it to the firmware.
Actually the firmware works on a coprocessor MGMT_CPU(inside the NIC)
which will recv and deal with these commands.

5bd78c00d7 phy: ti: gmii-sel: Add support for CPSW9G GMII SEL in J721e
Each of the CPSW9G ports in J721e support additional modes like QSGMII.
Add a new compatible for J721e to support the additional modes.

In TI's J721e, each of the CPSW9G ethernet interfaces can act as a
QSGMII main or QSGMII-SUB port. The QSGMII main interface is responsible
for performing auto-negotiation between the MAC and the PHY while the rest
of the interfaces are designated as QSGMII-SUB interfaces, indicating that
they will not be taking part in the auto-negotiation process.

3b66ab69c5 phy: ti: gmii-sel: Update methods for fetching and using qsgmii main port
The number of QSGMII main ports are specific to the device. TI's J7200 for
which the QSGMII main port property is fetched from the device-tree has
only one QSGMII main port. However, devices like TI's J721e support up to
two QSGMII main ports. Thus, the existing methods for fetching and using
the QSGMII main port are not scalable.

Update the existing methods for handling the QSGMII main ports and its
associated requirements to make it scalable for future devices.

0f60740652 phy: sun4i-usb: Add support for the H616 USB PHY
The USB PHY used in the Allwinner H616 SoC inherits some traits from its
various predecessors: it has four full PHYs like the H3, needs some
extra bits to be set like the H6, and puts SIDDQ on a different bit like
the A100. Plus it needs this weird PHY2 quirk.

Name all those properties in a new config struct and assign a new
compatible name to it.

b45c6d8032 phy: sun4i-usb: Introduce port2 SIDDQ quirk
At least the Allwinner H616 SoC requires a weird quirk to make most
USB PHYs work: Only port2 works out of the box, but all other ports
need some help from this port2 to work correctly: The CLK_BUS_PHY2 and
RST_USB_PHY2 clock and reset need to be enabled, and the SIDDQ bit in
the PMU PHY control register needs to be cleared. For this register to
be accessible, CLK_BUS_ECHI2 needs to be ungated. Don't ask ....

Instead of disguising this as some generic feature, treat it more like
a quirk (what it really is):
If the quirk bit is set, and we initialise a PHY other than PHY2, ungate
this one special clock, and clear the SIDDQ bit. We also pick the clock
and reset from PHY2 and enable them as well.

6964affe65 dt-bindings: phy: Add special clock for Allwinner H616 PHY
The USB PHY IP in the Allwinner H616 SoC requires a quirk that involves
some resources from port 2's PHY and HCI IP. In particular the PMU clock
for port 2 must be surely ungated before accessing the REG_HCI_PHY_CTL
register of port 2. To allow each USB port to be controlled
independently of port 2, we need a handle to that particular PMU clock
in the *PHY* node, as the HCI and PHY part might be handled by separate
drivers.

Add that clock to the requirements of the H616 PHY binding, so that a
PHY driver can apply the quirk in isolation, without requiring help from
port 2's HCI driver.

The phy auto-suspend feature turns off the phy when nothing is attached
leading to the PLL to not lock. This leads the BDC block to grab the AUX
