As the USB PHYs typically are on I2C or SPI bus for the 2430 glue layer,
we need configure the PHYs early for suspend.
The musb glue layer we need to suspend only after musb_suspend() in
suspend_late.
Fixes: 62d472d8ad88 ("usb: musb: Add missing PM suspend and resume functions for 2430 glue")

The USB HID standard declares mandatory support for GET_IDLE and SET_IDLE
requests for Boot Keyboard. Most hosts can handle their absence, but others
like some old/strange UEFIs and BIOSes consider this a critical error
and refuse to work with f_hid.
This primitive implementation of saving and returning idle is sufficient
to meet the requirements of the standard and these devices.

Disconnecting and reconnecting the USB cable can lead to crashes
and a variety of kernel log spam.
The problem was found and reproduced on the Raspberry Pi [1]
and the original fix was created in Raspberry's own fork [2].

The usb_add_gadget_udc will add a new gadget to the udc class
driver list. Not calling usb_del_gadget_udc in error branch
will result in residual gadget entry in the udc driver list.
We fix it by calling usb_del_gadget_udc to clean it when error
return.

The function usbtmc_interrupt() resubmits urbs when the error status
of an urb is -EPROTO. In systems using the dummy_hcd usb controller
this can result in endless interrupt loops when the usbtmc device is
disconnected from the host system.
Since host controller drivers already try to recover from transmission
errors, there is no need to resubmit the urb or try other solutions
to repair the error situation.
In case of errors the INT pipe just stops to wait for further packets.

Clock driver for this SoC is using some gates to properly enabling
and disabling the access to peripherals. Those gates that are not
in use are properly being automatically disabled by the kernel.
Pcie driver is explicitly doing a 'clk_disable_unprepare' call for
gates of those pcies that are not used. Since kernel has already
disabled them, the following warnings appear:

There was strange error handling logic in case of fw load failure. For
some reason fw loader callback was doing clean up stuff when fw is not
available. I don't see any reason behind doing this. Since this driver
doesn't have EEPROM firmware let's just disconnect it in case of fw load
failure. Doing clean up stuff in 2 different place which can run
concurently is not good idea and syzbot found 2 bugs related to this
strange approach.
So, in this pacth I deleted all clean up code from fw callback and made
a call to device_release_driver() under device_lock(parent) in case of fw
load failure. This approach is more generic and it defend driver from UAF
bugs, since all clean up code is moved to one place.

This patch is preparation for following patch for error handling
refactoring.
flush_scheduled_work() takes (wq_completion)events lock and
it can lead to deadlock when r871xu_dev_remove() is called from workqueue.
To avoid deadlock sutiation we can change flush_scheduled_work() call to
flush_work() call for all possibly scheduled works in this driver,
since next patch adds device_release_driver() in case of fw load failure.

The spi_imx->spi_bus_clk may be uninitialized and thus also zero in
mx51_ecspi_prepare_message(), which would lead to division by zero
in kernel. Since bitbang .setup_transfer callback which initializes
the spi_imx->spi_bus_clk is called after bitbang prepare_message
callback, iterate over all the transfers in spi_message, find the
one with lowest bus frequency, and use that bus frequency for the
delay calculation.
Note that it is not possible to move this CONFIGREG delay back into
the .setup_transfer callback, because that is invoked too late, after
the GPIO chipselects were already configured.

In case when psp_init_asd_microcode() fails to load ASD microcode file,
psp_v12_0_init_microcode() tries to print the firmware filename that
failed to load before bailing out.
This is wrong because:
- the firmware filename it would want it print is an incorrect one as
psp_init_asd_microcode() and psp_v12_0_init_microcode() are loading
different filenames
- it tries to print fw_name, but that's not yet been initialized by that
time, so it prints random stack contents, e.g.
amdgpu 0000:04:00.0: Direct firmware load for amdgpu/renoir_asd.bin failed with error -2
amdgpu 0000:04:00.0: amdgpu: fail to initialize asd microcode
amdgpu 0000:04:00.0: amdgpu: psp v12.0: Failed to load firmware "\xfeTO\x8e\xff\xff"
Fix that by bailing out immediately, instead of priting the bogus error
message.

This reverts commit 4192f7b5768912ceda82be2f83c87ea7181f9980.
It is not true (as stated in the reverted commit changelog) that we never
unmap the BAR on failure; it actually does happen properly on
amdgpu_driver_load_kms() -> amdgpu_driver_unload_kms() ->
amdgpu_device_fini() error path.
What's worse, this commit actually completely breaks resource freeing on
probe failure (like e.g. failure to load microcode), as
amdgpu_driver_unload_kms() notices adev->rmmio being NULL and bails too
early, leaving all the resources that'd normally be freed in
amdgpu_acpi_fini() and amdgpu_device_fini() still hanging around, leading
to all sorts of oopses when someone tries to, for example, access the
sysfs and procfs resources which are still around while the driver is
gone.

ql_adapter_reset
When calling the 'ql_wait_for_drvr_lock' and 'ql_adapter_reset', the driver
has already acquired the spin lock, so the driver should not call 'ssleep'
in atomic context.
This bug can be fixed by using 'mdelay' instead of 'ssleep'.

Commit 5a9d38b20a5a ("drm/i915/display: hide workaround for broken vbt
in intel_bios.c") moved the workaround for broken or missing VBT to
intel_bios.c. However is_port_valid() only protects the handling of
different skus of the same display version. Since in
intel_setup_outputs() we share the code path with version 9, this would
also create port F for SKL/KBL, which does not exist.
Missing VBT can be reproduced when starting a headless QEMU with no
opregion available.
Avoid the issue by splitting versions 9 and 10 in intel_setup_outputs(),
which also makes it more clear what code path it's taking for each
version.
v2: move generic display version after Geminilake since that one has
a different set of outputs

We were using GRAPHICS_VER() to handle SKL_DFSM register, which means we
were not handling GLK correctly since that has GRAPHICS_VER == 9, but
DISPLAY_VER == 10. Switch the entire branch to check DISPLAY_VER
which makes it more in line with Bspec.
Even though the Bspec has an exception for RKL in
TGL_DFSM_PIPE_D_DISABLE, we don't have to do anything as the bit has
disable semantic and RKL doesn't have pipe D.

In the existing code while changing the number of TX/RX
queues using ethtool the PF/VF interface resources are
freed and reallocated (otx2_stop and otx2_open is called)
if the device is in running state. If any resource allocation
fails in otx2_open, driver free already allocated resources
and return. But again, when the number of queues changes
as the device state still running oxt2_stop is called.
In which we try to free already freed resources leading
to driver crash.
This patch fixes the issue by setting the INTF_DOWN flag on
error and free the resources in otx2_stop only if the flag is
not set.

Currently PKINDs are not assigned to LBK channels.
The default value of LBK_CHX_PKIND (channel to PKIND mapping) register
is zero, which is resulting in a overlap of pkind between LBK and CGX
LMACs. When KPU1 parser config is modified when PTP timestamping is
enabled on the CGX LMAC interface it is impacting traffic on LBK
interfaces as well.
This patch fixes the issue by reserving the PKIND#0 for LBK devices.
CGX mapped PF pkind starts from 1 and also fixes the max pkind available.

In case an error occurred in the IRQ handler, the chip status is
dumped via devcoredump and all IRQs are disabled, but the chip stays
powered for further analysis.
The chip is in an undefined state and will not receive any CAN frames,
so shut down the timestamping worker, which reads the TBC register
regularly, too. This avoids any CRC read error messages if there is a
communication problem with the chip.
