Add edp-tx and dp-tx nodes for the Embedded DisplayPort (eDP) and

efuse cell for the DP calibration data.
Individual board device tree should enable the nodes and connect input

Enable the Mali Valhall GPU on Genio 1200 EVK by providing regulator
supply settingsi to gpu and mfg1, and enable the GPU node.
In addition, set the GPU related regulator voltage range:
1. Set the recommended input voltage range of DVDD_GPU to (0.546V-0.787V),
based on Table 5-3 of MT8395 Application Processor Datasheet.
The regulator mt6315_7_vbuck1("Vgpu") connects to the DVDD_GPU input.
Note that the minimum voltage in SoC eFuse data, which is read by
MTK-SVS to adjust the regulator voltage, does not go below
the recommended operating voltage in the datasheet.
2. Set the input voltage of DVDD_SRAM_GPU, supplied by
mt6359_vsram_others_ldo_reg, to 0.75V, the recommended typical
operating voltage in MT8395 Application Processor Datasheet.
This patch is tested by enabling CONFIG_DRM_PANFROST and
on Genio 1200 EVK it probed with following dmesg:
```

This way user_mode(regs) will return false, like it should.
It looks like all current users initialize regs to zero, so that this

to do this.

According to the VT220 specification the possible character combinations
sent on RETURN are only CR or CRLF [0].
The Return key sends either a CR character (0/13) or a CR
character (0/13) and an LF character (0/10), depending on the
set/reset state of line feed/new line mode (LNM).
The sclp/vt220 driver however uses LFCR. This can confuse tools, for
example the kunit runner.

On reboot the SCLP interface is deactivated through a reboot notifier.
This happens before other components using SCLP have the chance to run
their own reboot notifiers.
Two of those components are the SCLP console and tty drivers which try
to flush the last outstanding messages.
At that point the SCLP interface is already unusable and the messages
are discarded.
Execute sclp_deactivate() as late as possible to avoid this issue.

The configfs store callback should return the number of bytes consumed
not the total number of bytes we actually stored. These could differ if
for example the passed in string had a newline we did not store.
If the returned value does not match the number of bytes written the
writer might assume a failure or keep trying to write the remaining bytes.
For example the following command will hang trying to write the final
newline over and over again (tested on bash 2.05b):
echo foo > function_name

Since commit 6d735722063a ("usb: dwc3: core: Prevent phy suspend during init"),
system suspend is broken on AM62 TI platforms.
Before that commit, both DWC3_GUSB3PIPECTL_SUSPHY and DWC3_GUSB2PHYCFG_SUSPHY
bits (hence forth called 2 SUSPHY bits) were being set during core
initialization and even during core re-initialization after a system
suspend/resume.
These bits are required to be set for system suspend/resume to work correctly
on AM62 platforms.
Since that commit, the 2 SUSPHY bits are not set for DEVICE/OTG mode if gadget
driver is not loaded and started.
For Host mode, the 2 SUSPHY bits are set before the first system suspend but
get cleared at system resume during core re-init and are never set again.
This patch resovles these two issues by ensuring the 2 SUSPHY bits are set
before system suspend and restored to the original state during system resume.

DWC3 programming guide mentions that when operating in USB2.0 speeds,
if GUSB2PHYCFG[6] or GUSB2PHYCFG[8] is set, it must be cleared prior
to issuing commands and may be set again after the command completes.
But currently while issuing EndXfer command without CmdIOC set, we
wait for 1ms after GUSB2PHYCFG is restored. This results in cases
where EndXfer command doesn't get completed and causes SMMU faults
since requests are unmapped afterwards. Hence restore GUSB2PHYCFG
after waiting for EndXfer command completion.

Add an overlay file to enable I3C support on the i.MX93, replacing I2C1
with I3C. I3C is compatible with I2C, but it has not yet been enabled in
arm64's defconfig. This overlay allows users to conveniently utilize I3C
on the imx93-9x9-qsb platform until I3C and its driver become more mature
and ready for full switch to I3C.

When using encryption, either enforced by the server or when using
'seal' mount option, the client will squash all compound request buffers
down for encryption into a single iov in smb2_set_next_command().
SMB2_ioctl_init() allocates a small buffer (448 bytes) to hold the
SMB2_IOCTL request in the first iov, and if the user passes an input
buffer that is greater than 328 bytes, smb2_set_next_command() will
end up writing off the end of @rqst->iov[0].iov_base as shown below:
mount.cifs //srv/share /mnt -o ...,seal
ln -s $(perl -e "print('a')for 1..1024") /mnt/link

Clang static checker(scan-build) warning：

There is a double free in such case:
'ea is initialized to NULL' -> 'first successful memory allocation for
ea' -> 'something failed, goto sea_exit' -> 'first memory release for ea'
-> 'goto replay_again' -> 'second goto sea_exit before allocate memory
for ea' -> 'second memory release for ea resulted in double free'.
Re-initialie 'ea' to NULL near to the replay_again label, it can fix this
double free problem.
