For real commits we WARN if ->hw_done hasn't been completed by the time
drm_atomic_helper_commit_cleanup_done() is called. Let's do the same for
the fake commit.

Consider the following scenario:
1. nonblocking enable crtc
2. wait for the event
3. nonblocking disable crtc
On i915 this can lead to a spurious -EBUSY from step 3 on
account of non-enabled planes getting the fake_commit in step 1
and we don't complete the fake_commit-> flip_done until
drm_atomic_helper_commit_hw_done() which can happen a long
time after the flip event was sent out.
This will become somewhat easy to hit on SKL+ once we start
to add all the planes for the crtc to every modeset commit
for the purposes of forcing a watermark register programming
[1].
To make the race a little less pronounced let's complete
fake_commit->flip_done after drm_atomic_helper_wait_for_flip_done().
For the single crtc case this should make the race quite
theoretical, assuming drm_atomic_helper_wait_for_flip_done()
actually has to wait for the real commit flip_done. In case
the real commit flip_done gets completed singificantly before
drm_atomic_helper_wait_for_flip_done(), or we are dealing with
multiple crtcs whose vblanks don't line up nicely the race still
exists.

The hardware requires the HDSR and VDSR registers to be set to 1 or
higher. This translates to a minimum combined horizontal sync and back
porch of 20 pixels and a minimum vertical back porch of 3 lines. Reject
modes that fail those requirements.

The rcar-du driver supports probe deferral for external clocks, but
implements it badly by checking the wrong pointer due to a bad copy and
paste. Fix it.
While at it, reject invalid clocks outright for DU channels that have a
display PLL, as the external clock is mandatory in that case. This
avoids a WARN_ON() at runtime.

interrupts
In the original ftmac100_interrupt(), the interrupts are only disabled when
the condition "netif_running(netdev)" is true. However, this condition
causes kerenl hang in the following case. When the user requests to
disable the network device, kernel will clear the bit __LINK_STATE_START
from the dev->state and then call the driver's ndo_stop function. Network
device interrupts are not blocked during this process. If an interrupt
occurs between clearing __LINK_STATE_START and stopping network device,
kernel cannot disable the interrupts due to the condition
"netif_running(netdev)" in the ISR. Hence, kernel will hang due to the
continuous interruption of the network device.
In order to solve the above problem, the interrupts of the network device
should always be disabled in the ISR without being restricted by the
condition "netif_running(netdev)".

git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers
Kalle Valo says:
====================
wireless-drivers fixes for 4.20
First set of fixes for 4.20, this time we have quite a few them but
all very small.
ath9k
* fix a locking regression found by a static checker
wlcore
* fix a crash which was a regression with wakeirq handling
brcm80211
* yet another fix for 160 MHz channel handling
mt76
* fix a longstaning build problem when CONFIG_LEDS_CLASS is disabled
* don't use uninitialised mutex
iwlwifi
* do note that the iwlwifi merge tag (commit 4ec321c14693) seems to
contain wrong list of changes so ignore that
* fix ACPI data handling, a memory leak and other smaller fixes
ath10k
* fix a crash during suspend which was a recent regression
====================

When showing the list of waiters, include the task's status so that we
can tell if they have been woken up and are waiting for the CPU, or if
they are still waiting to be woken.

If we need to force a full plane update before userspace/fbdev
have given us a proper plane state we should try to maintain the
current plane state as much as possible (apart from the parts
of the state we're trying to fix up with the plane update).
To that end add basic readout for the plane rotation and
maintain it during the initial fb takeover.

If we force a plane update to fix up our half populated plane state
we'll also force on the pipe gamma for the plane (since we always
enable pipe gamma currently). If the BIOS hasn't programmed a sensible
LUT into the hardware this will cause the image to become corrupted.
Typical symptoms are a purple/yellow/etc. flash when the driver loads.
To avoid this let's program something sensible into the LUT when
we do the plane update. In the future I plan to add proper plane
gamma enable readout so this is just a temporary measure.

Many HP AMD based laptops contain an SMB0001 device like this:
Device (SMBD)
{
Name (_HID, "SMB0001") // _HID: Hardware ID
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
{
IO (Decode16,
0x0B20, // Range Minimum
0x0B20, // Range Maximum
0x20, // Alignment
0x20, // Length
)
IRQ (Level, ActiveLow, Shared, )
{7}
})
}
The legacy style IRQ resource here causes acpi_dev_get_irqresource() to
be called with legacy=true and this message to show in dmesg:
ACPI: IRQ 7 override to edge, high
This causes issues when later on the AMD0030 GPIO device gets enumerated:
Device (GPIO)
{
Name (_HID, "AMDI0030") // _HID: Hardware ID
Name (_CID, "AMDI0030") // _CID: Compatible ID
Name (_UID, Zero) // _UID: Unique ID
Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings
{
Name (RBUF, ResourceTemplate ()
{
Interrupt (ResourceConsumer, Level, ActiveLow, Shared, ,, )
{
0x00000007,
}
Memory32Fixed (ReadWrite,
0xFED81500, // Address Base
0x00000400, // Address Length
)
})
Return (RBUF) /* \_SB_.GPIO._CRS.RBUF */
}
}
Now acpi_dev_get_irqresource() gets called with legacy=false, but because
of the earlier override of the trigger-type acpi_register_gsi() returns
-EBUSY (because we try to register the same interrupt with a different
trigger-type) and we end up setting IORESOURCE_DISABLED in the flags.
The setting of IORESOURCE_DISABLED causes platform_get_irq() to call
acpi_irq_get() which is not implemented on x86 and returns -EINVAL.
resulting in the following in dmesg:
amd_gpio AMDI0030:00: Failed to get gpio IRQ: -22
amd_gpio: probe of AMDI0030:00 failed with error -22
The SMB0001 is a "virtual" device in the sense that the only way the OS
interacts with it is through calling a couple of methods to do SMBus
transfers. As such it is weird that it has IO and IRQ resources at all,
because the driver for it is not expected to ever access the hardware
directly.
The Linux driver for the SMB0001 device directly binds to the acpi_device
through the acpi_bus, so we do not need to instantiate a platform_device
for this ACPI device. This commit adds the SMB0001 HID to the
forbidden_id_list, avoiding the instantiating of a platform_device for it.
Not instantiating a platform_device means we will no longer call
acpi_dev_get_irqresource() for the legacy IRQ resource fixing the probe of
the AMDI0030 device failing.
