Make sure to remove the software node also on (ACPI) probe errors to
avoid leaking the underlying resources.
Note that the software node is only used for ACPI probe so the driver
unbind tear down is updated to match probe.

The driver needs to deregister and free the newly allocated dwc3 core
platform device on ACPI probe errors (e.g. probe deferral) and on driver
unbind but instead it leaked those resources while erroneously dropping
a reference to the parent platform device which is still in use.
For OF probing the driver takes a reference to the dwc3 core platform
device which has also always been leaked.
Fix the broken ACPI tear down and make sure to drop the dwc3 core
reference for both OF and ACPI.

The Qualcomm glue driver is overriding the interrupt trigger types
defined by firmware when requesting the wakeup interrupts during probe.
This can lead to a failure to map the DP/DM wakeup interrupts after a
probe deferral as the firmware defined trigger types do not match the
type used for the initial mapping:
irq: type mismatch, failed to map hwirq-14 for interrupt-controller@b220000!
irq: type mismatch, failed to map hwirq-15 for interrupt-controller@b220000!
Fix this by not overriding the firmware provided trigger types when
requesting the wakeup interrupts.

Add support for the Microchip USB5744 USB3.0 and USB2.0 Hub.
The Microchip USB5744 supports two power supplies, one for 1V2 and one
for 3V3. According to the datasheet there is no need for a delay between
power on and reset, so this value is set to 0.

This reverts commit efa5f1311c4998e9e6317c52bc5ee93b3a0f36df.
I couldn't reproduce the reported issue. What I did, based on a pcap
packet log provided by the reporter:
- Used same chip version (RTL8168h)
- Set MAC address to the one used on the reporters system
- Replayed the EAPOL unicast packet that, according to the reporter,
was filtered out by the mc filter.
The packet was properly received.
Therefore the root cause of the reported issue seems to be somewhere
else. Disabling mc filtering completely for the most common chip
version is a quite big hammer. Therefore revert the change and wait
for further analysis results from the reporter.

Not all LJCA chips implement SPI and on chips without SPI reading
the SPI descriptors will timeout.
On laptop models like the Dell Latitude 9420, this is expected behavior
and not an error.
Modify the driver to continue without instantiating a SPI auxbus child,
instead of failing to probe() the whole LJCA chip.

The commit c7d80059b086 ("leds: class: Store the color index in struct
led_classdev") introduced a new sysfs entry "color" that is commonly
created for the led classdev. Unfortunately, this conflicts with the
"color" sysfs entry of already existing drivers such as Logitech HID
or System76 ACPI drivers. The driver probe fails due to the conflict,
hence it leads to a severe regression with the missing keyboard, for
example.
This patch reverts partially the change in the commit above for
removing the led class color sysfs entries again for addressing the
regressions. The newly introduced led_classdev.color field is kept as
it's already used by other driver.

Honor MagicBook 13 2023 has a touchpad which do not switch to the multitouch
mode until the input mode feature is written by the host. The touchpad do
report the input mode at touchpad(3), while itself working under mouse mode. As
a workaround, it is possible to call MT_QUIRE_FORCE_GET_FEATURE to force set
feature in mt_set_input_mode for such device.
The touchpad reports as BLTP7853, which cannot retrive any useful manufacture
information on the internel by this string at present. As the serial number of
the laptop is GLO-G52, while DMI info reports the laptop serial number as
GLO-GXXX, this workaround should applied to all models which has the GLO-GXXX.

Some devices managed by this driver automatically set brightness to 0
before entering a suspended state and reset it back to a default
brightness level after the resume:
this has the effect of having the kernel report wrong brightness
status after a sleep, and on some devices (like the Asus RC71L) that
brightness is the intensity of LEDs directly facing the user.
Fix the above issue by setting back brightness to the level it had
before entering a sleep state.

Using generic ASIX Electronics Corp. AX88179 Gigabit Ethernet device,
the following test cycle has been implemented:
- power on
- check logs
- shutdown
- after detecting the system shutdown, disconnect power
- after approximately 60 seconds of sleep, power is restored
Running some cycles, sometimes error logs like this appear:
kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to write reg index 0x0001: -19
kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to read reg index 0x0001: -19
...
These failed operation are happening during ax88179_reset execution, so
the initialization could not be correct.
In order to avoid this, we need to increase the delay after reset and
clock initial operations. By using these larger values, many cycles
have been run and no failed operations appear.
It would be better to check some status register to verify when the
operation has finished, but I do not have found any available information
(neither in the public datasheets nor in the manufacturer's driver). The
only available information for the necessary delays is the maufacturer's
driver (original values) but the proposed values are not enough for the
tested devices.

This probably isn't the ideal fix, but we ended up using chids
sparsely, and lots of things rely on indexing into the full range,
so just allocate the full range up front.
The GSP code fixes 8 channels into a userd page, but we end up using
a single userd page per channel so end up sparsely using the range.
Fixes a few crashes seen with multiple channels.

The refresh reported by modetest is 60.46Hz, and the actual measurement
is 60.01Hz, which is outside the expected tolerance. Adjust hporch and
pixel clock to fix it. After repair, modetest and actual measurement were
all 60.01Hz.
Modetest refresh = Pixel CLK/ htotal* vtotal, but measurement frame rate
is HS->LP cycle time(Vblanking). Measured frame rate is not only affecte
by Htotal/Vtotal/pixel clock, also affected by Lane-num/PixelBit/LineTime
/DSI CLK. Assume that the DSI controller could not make the mode that we
requested(presumably it's PLL couldn't generate the exact pixel clock?).
If you use a different DSI controller, you may need to readjust these
parameters. Now this panel looks like it's only used by me on the MTK
platform, so let's change this set of parameters.

Commits 7b8ef22ea547 ("usb: xhci: plat: Add USB phy support") and
9134c1fd0503 ("usb: xhci: plat: Add USB 3.0 phy support") added support
for looking up legacy PHYs from the sysdev devicetree node and
initialising them.
This broke drivers such as dwc3 which manages PHYs themself as the PHYs
would now be initialised twice, something which specifically can lead to
resources being left enabled during suspend (e.g. with the
usb_phy_generic PHY driver).
As the dwc3 driver uses driver-name matching for the xhci platform
device, fix this by only looking up and initialising PHYs for devices
that have been matched using OF.
Note that checking that the platform device has a devicetree node would
currently be sufficient, but that could lead to subtle breakages in case
anyone ever tries to reuse an ancestor's node.

It's wrong to use the data length in a CS (in uframe x) to check whether
there is a SS (in uframe x-2), because for a isoc-in ep, it may need some
CS to receive data;
Save the count of SS in a uframe for isoc/intr in-eps to fix the issue.

The BOS descriptor defines a root descriptor and is the base descriptor for
accessing a family of related descriptors.
Function 'usb_get_bos_descriptor()' encounters an iteration issue when
skipping the 'USB_DT_DEVICE_CAPABILITY' descriptor type. This results in
the same descriptor being read repeatedly.
To address this issue, a 'goto' statement is introduced to ensure that the
pointer and the amount read is updated correctly. This ensures that the
function iterates to the next descriptor instead of reading the same
descriptor repeatedly.

Currently the shipped platforms use only _HID to distinguish

This patch is to drop _ADR support and we can then re-introduce
it (revert this patch) if future HW actually starts using _ADR

The interrupt service routine registered for the gadget is a primary
handler which mask the interrupt source and a threaded handler which
handles the source of the interrupt. Since the threaded handler is
voluntary threaded, the IRQ-core does not disable bottom halves before
invoke the handler like it does for the forced-threaded handler.
Due to changes in networking it became visible that a network gadget's
completions handler may schedule a softirq which remains unprocessed.
The gadget's completion handler is usually invoked either in hard-IRQ or
soft-IRQ context. In this context it is enough to just raise the softirq
because the softirq itself will be handled once that context is left.
In the case of the voluntary threaded handler, there is nothing that
will process pending softirqs. Which means it remain queued until
another random interrupt (on this CPU) fires and handles it on its exit
path or another thread locks and unlocks a lock with the bh suffix.
Worst case is that the CPU goes idle and the NOHZ complains about
unhandled softirqs.
Disable bottom halves before acquiring the lock (and disabling
interrupts) and enable them after dropping the lock. This ensures that
any pending softirqs will handled right away.

The rtnl lock also needs to be held before rndis_filter_device_add()

VF NIC offering and registering. If VF NIC finished register_netdev()
earlier it may cause name based config failure.
To fix this issue, move the call to rtnl_lock() before

The Glorious Model I mouse has a buggy HID report descriptor for its
keyboard endpoint (used for programmable buttons). For report ID 2, there
is a mismatch between Logical Minimum and Usage Minimum in the array that
reports keycodes.
The offending portion of the descriptor: (from hid-decode)
0x95, 0x05, // Report Count (5) 30
0x75, 0x08, // Report Size (8) 32
0x15, 0x00, // Logical Minimum (0) 34
0x25, 0x65, // Logical Maximum (101) 36
0x05, 0x07, // Usage Page (Keyboard) 38
0x19, 0x01, // Usage Minimum (1) 40
0x29, 0x65, // Usage Maximum (101) 42
0x81, 0x00, // Input (Data,Arr,Abs) 44
This bug shifts all programmed keycodes up by 1. Importantly, this causes
"empty" array indexes of 0x00 to be interpreted as 0x01, ErrorRollOver.
The presence of ErrorRollOver causes the system to ignore all keypresses
from the endpoint and breaks the ability to use the programmable buttons.
Setting byte 41 to 0x00 fixes this, and causes keycodes to be interpreted
correctly.
Also, USB_VENDOR_ID_GLORIOUS is changed to USB_VENDOR_ID_SINOWEALTH,
and a new ID for Laview Technology is added. Glorious seems to be
white-labeling controller boards or mice from these vendors. There isn't a
single canonical vendor ID for Glorious products.

Jamesdonkey A3R keyboard is identified as "Jamesdonkey A3R" in wired
mode, "A3R-U" in wireless mode and "A3R" in bluetooth mode. Adding them
to non-apple keyboards fixes function key.

During the probe we add an I2C adapter and as soon as we add that adapter
it may be used for a transfer (e.g via the code in i2cdetect()).
Those transfers are not able to complete and time out. This is because the
HID raw_event callback (mcp2221_raw_event) will not be invoked until the
HID device's 'driver_input_lock' is marked up at the completion of the
probe in hid_device_probe(). This starves the driver of the responses it
is waiting for.
In order to allow the I2C transfers to complete while we are still in the
probe, start the IO once we have completed init of the HID device.
This issue seems to have been seen before and a patch was submitted but
it seems it was never accepted. See:

The process of adding an I2C adapter can invoke I2C accesses on that new
adapter (see i2c_detect()).
Ensure we have set the adapter's driver data to avoid null pointer
dereferences in the xfer functions during the adapter add.
This has been noted in the past and the same fix proposed but not
completed. See:

There is no need to call MMIO reset using VPU_37XX_BUTTRESS_VPU_IP_RESET
register. IP will be reset by FLR or by entering d0i3. Also IP reset
during power_up is not needed as the VPU is already in reset.
Removing MMIO reset improves stability as it a partial device reset
that is not safe in some corner cases.
This change also brings back ivpu_boot_pwr_domain_disable() that
helps to properly power down VPU when it is hung by a buggy workload.

LKP found issues with a kernel doc in the driver:
core.c:116: warning: Function parameter or member 'ioss_evtconfig' not described in 'telemetry_update_events'
core.c:188: warning: Function parameter or member 'ioss_evtconfig' not described in 'telemetry_get_eventconfig'
It looks like it were copy'n'paste typos when these descriptions
had been introduced. Fix the typos.
