The vc4 planes are setup in hardware by creating a hardware descriptor
in a dedicated RAM. As part of the process to setup a plane in KMS, we
thus need to allocate some part of that dedicated RAM to store our
descriptor there.
The async update path will just reuse the descriptor already allocated
for that plane and will modify it directly in RAM to match whatever has
been asked for.
In order to do that, it will compare the descriptor for the old plane
state and the new plane state, will make sure they fit in the same size,
and check that only the position or buffer address have changed.

noop_backing_dev_info is used by superblocks of various
pseudofilesystems such as kdevtmpfs. After commit 10e14073107d
("writeback: Fix inode->i_io_list not be protected by inode->i_lock
error") this broke because __mark_inode_dirty() started to access more
fields from noop_backing_dev_info and this led to crashes inside
locked_inode_to_wb_and_lock_list() called from __mark_inode_dirty().
Fix the problem by initializing noop_backing_dev_info before the
filesystems get mounted.

If the component driver fails to bind, or is unbound, the driver data
for the top-level platform device points to a freed drm_device. If the
system is then suspended, the driver passes this dangling pointer to
drm_mode_config_helper_suspend(), which crashes.
Fix this by only setting the driver data while the platform driver holds
a reference to the drm_device.

commit 6de79dd3a920 ("drm/bridge: display-connector: add ddc-en gpio
support") added a consumer for this GPIO in the HDMI connector device.
This new consumer conflicts with the pre-existing GPIO consumer in the
sun8i HDMI controller driver, which prevents the driver from probing:
[ 4.983358] display-connector connector: GPIO lookup for consumer ddc-en
[ 4.983364] display-connector connector: using device tree for GPIO lookup
[ 4.983392] gpio-226 (ddc-en): gpiod_request: status -16
[ 4.983399] sun8i-dw-hdmi 6000000.hdmi: Couldn't get ddc-en gpio
[ 4.983618] sun4i-drm display-engine: failed to bind 6000000.hdmi (ops sun8i_dw_hdmi_ops [sun8i_drm_hdmi]): -16
[ 4.984082] sun4i-drm display-engine: Couldn't bind all pipelines components

[ 4.984179] sun8i-dw-hdmi: probe of 6000000.hdmi failed with error -16
Both drivers have the same behavior: they leave the GPIO active for the
life of the device. Let's take advantage of the new implementation, and
drop the now-obsolete code from the HDMI controller driver.

Since the driver already needs to support multiple sets of ops, we can
drop the mid-layer used by the A83T and H3 PHYs. They share only a small

Keep the warn, but drop the early return. If we do manage to hit this
sort of issue, skipping the cleanup just makes things worse (dangling
drm_mm_nodes when the msm_gem_vma is freed, etc). Whereas the worst
that happens if we tear down a mapping the GPU is accessing is that we
get GPU iova faults, but otherwise the world keeps spinning.

Previously the BO_PINNED state in the submit was tracking two related
but different things: (1) that the buffer object was pinned, and (2)
that the vma (mapping within a set of pagetables) was pinned. But with
fenced vma unpin (needed so that userspace couldn't race with retire
path for releasing a vma) these two were decoupled. The fact that the
BO_PINNED flag was already cleared meant that we leaked the bo pin count
which should have been dropped when the submit was retired.
So split this state into BO_OBJ_PINNED and BO_VMA_PINNED, so they can be
dropped independently.

MediaTek IP requires that after dma stop, it need to wait this dma stop
bit auto-reset to 0. When bus is in high loading state, it will take a
while for the dma stop complete. If there is no waiting operation here,
when program runs to clear fifo and reset, bus will hang.
In addition, there should be no return in msdc_data_xfer_next() if
there is data need be transferred, because no matter what error occurs
here, it should continue to excute to the following mmc_request_done.
Otherwise the core layer may wait complete forever.

While parsing the DT, the anx7625 driver checks for the presence of a
panel bridge on endpoint 1. If it is missing, pdata->panel_bridge stores
the error pointer and the function returns successfully without first
cleaning that variable. This is an issue since other functions later
check for the presence of a panel bridge by testing the trueness of that
variable.
In order to ensure proper behavior, zero out pdata->panel_bridge before
returning when no panel bridge is found.

The extra byte inserted by usbnet.c when
(length % dev->maxpacket == 0) is causing problems to device.
This patch sets FLAG_SEND_ZLP to avoid this.
Tested with: 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet
Problems observed:
======================================================================
1) Using ssh/sshfs. The remote sshd daemon can abort with the message:
"message authentication code incorrect"
This happens because the tcp message sent is corrupted during the
USB "Bulk out". The device calculate the tcp checksum and send a
valid tcp message to the remote sshd. Then the encryption detects
the error and aborts.
2) NETDEV WATCHDOG: ... (ax88179_178a): transmit queue 0 timed out
3) Stop normal work without any log message.
The "Bulk in" continue receiving packets normally.
The host sends "Bulk out" and the device responds with -ECONNRESET.
(The netusb.c code tx_complete ignore -ECONNRESET)
Under normal conditions these errors take days to happen and in
intense usage take hours.
A test with ping gives packet loss, showing that something is wrong:
ping -4 -s 462 {destination} # 462 = 512 - 42 - 8
Not all packets fail.
My guess is that the device tries to find another packet starting
at the extra byte and will fail or not depending on the next
bytes (old buffer content).

[Why]
All displays need to be blanked during the uclk OC interface so that we can
guarantee pstate switching support. If the display config doesn't support
pstate switching, only using core_link_disable_stream will not enable it
as the front-end is untouched. We need to go through the full plane removal
sequence to properly program the pipe to allow pstate switching.

[WHY]
The display driver on some OSes need to track it in order to
perform memory clock switching decisions.
[HOW]
Propagate the vrr active state to dirty bit so that on mode set it
disables dynamic memory clock switching.

[Why]
- Currently there is no support for HF-VSIF
- The current support of VSIF is limited to H14b infoframe
[How]
- refactor VSIF
- Added new builder for HF-VSIF
- Added the HF-VSIF packet to DisplayTarget
- Updates DC to apply HF-VSIF updates when updating streams

[WHY]
Memory clock switching has great potential for power savings.
[HOW]
The driver code was modified to notify the DMCUB firmware that it should
stretch the vertical blank of frames when a memory clock switch is about
to start so that no blackouts happen on the screen due to unavailability
of the frame buffer.
The driver logic to determine when such firmware assisted strategy can
be initiated is also implemented and consists on checking prerequisites
of the feature.
