Add an API to reset the encoder related hw blocks to ensure
a proper teardown of the pipeline. At the moment this is being
used only for the writeback encoder but eventually we can start
using this for all interfaces.

Rename dpu_hw_pipe_cdp_cfg to dpu_hw_cdp_cfg and move it
to dpu_hw_utils file so that other modules in addition to
SSPP such as writeback can use it as all the fields can
be used by writeback as well.

For vendors drivers which pass an already allocated and
initialized encoder especially for cases where the encoder
hardware is shared OR the writeback encoder shares the resources

drm_writeback_connector_init_with_encoder() which expects
an initialized encoder as a parameter and only sets up the
writeback connector.

It's typical for the bootloader to bring up the display for showing a
boot splash or efi framebuffer. But in some cases the kernel driver ends
up only partially configuring (in particular) the DPU, which might
result in e.g. that two different data paths attempts to push data to
the interface - with resulting graphical artifacts.
Naturally the end goal would be to inherit the bootloader's
configuration and provide the user with a glitch free handover from the
boot configuration to a running DPU.
But as implementing seamless transition from the bootloader
configuration to the running OS will be a considerable effort, start by
simply resetting the entire MDSS to its power-on state, to avoid the
partial configuration.

- There are two versions of inline rotators, v1 (present on sm8250 and

formats and in the scaler possibilities.

As per the specification of DPU_CTL_ACTIVE_CFG the configuration of
active blocks should be proactively specified, and the pingpong block is
no different.
The downstream display driver [1] confirms this by also calling
bind_pingpong_blk on CTL_ACTIVE_CFG. Note that this else-if is always
entered, as setup_intf_cfg - unlike this mainline dpu driver that
combines both behind the same function pointer - is left NULL in favour
of using setup_intf_cfg_v1 when CTL_ACTIVE_CFG is set.
This solves continuous timeouts on at least the Qualcomm sm6125 SoC:
[drm:dpu_encoder_frame_done_timeout:2091] [dpu error]enc31 frame done timeout
[drm:_dpu_encoder_phys_cmd_handle_ppdone_timeout.isra.0] *ERROR* id:31 pp:0 kickoff timeout 0 cnt 1 koff_cnt 1
[drm:dpu_encoder_phys_cmd_prepare_for_kickoff] *ERROR* failed wait_for_idle: id:31 ret:-110 pp:0
In the same way this pingpong block should also be unbound followed by
an interface flush when the encoder is disabled, according to the
downstream display driver [2].

Based on the discussions on the mailing list, document enum
dpu_intf_type and it's controversial fields: INTF_DP and INTF_EDP.
INTF_EDP is used for older eDP interface found on msm8x74/msm8x84
INTF_DP is used for both eDP and DP interfaces handled by the msm/dp
driver. The DPU driver does not make a difference between them.

After scan aborts we still receive some hw scan c2h packets, and
processing these c2h commands will change current channel. If device
already connect to other AP, driver will set wrong op channel due
to current channel changed. The disconnection happens when hw scan back
to wrong op channel that device can't receive beacon from AP. To fix
this issue, we ignore the late c2h if we are not scanning, and set
current channel back to op channel after scan to align the FW behavior.

Apple SoCs such as the M1 come with multiple embedded co-processors
running proprietary firmware. Communication with those is established
over a simple mailbox using the RTKit IPC protocol.
This cannot be implemented inside the mailbox subsystem since on top
of communication over channels we also need support for starting,
hibernating and resetting these co-processors. We also need to
handle shared memory allocations differently depending on the
co-processor and don't want to split that across multiple drivers.

We want to allow the code inside drivers/soc/apple to be compiled with
COMPILE_TEST but this will currently result in linking errors because
ARCH_APPLE is not set and make will never recurse into
drivers/soc/apple.
Let's just unconditionally recurse into apple/ since all drivers
in there are guarded by config options anyways.

nfcmrvl_nci_unregister_dev to avoid bugs
There are destructive operations such as nfcmrvl_fw_dnld_abort and
gpio_free in nfcmrvl_nci_unregister_dev. The resources such as firmware,
gpio and so on could be destructed while the upper layer functions such as
nfcmrvl_fw_dnld_start and nfcmrvl_nci_recv_frame is executing, which leads
to double-free, use-after-free and null-ptr-deref bugs.
There are three situations that could lead to double-free bugs.
The first situation is shown below:
(Thread 1) | (Thread 2)
nfcmrvl_fw_dnld_start |
... | nfcmrvl_nci_unregister_dev
release_firmware() | nfcmrvl_fw_dnld_abort
kfree(fw) //(1) | fw_dnld_over
| release_firmware
... | kfree(fw) //(2)
| ...
The second situation is shown below:
(Thread 1) | (Thread 2)
nfcmrvl_fw_dnld_start |
... |
mod_timer |
(wait a time) |
fw_dnld_timeout | nfcmrvl_nci_unregister_dev
fw_dnld_over | nfcmrvl_fw_dnld_abort
release_firmware | fw_dnld_over
kfree(fw) //(1) | release_firmware
... | kfree(fw) //(2)
The third situation is shown below:
(Thread 1) | (Thread 2)
nfcmrvl_nci_recv_frame |
if(..->fw_download_in_progress)|
nfcmrvl_fw_dnld_recv_frame |
queue_work |
|
fw_dnld_rx_work | nfcmrvl_nci_unregister_dev
fw_dnld_over | nfcmrvl_fw_dnld_abort
release_firmware | fw_dnld_over
kfree(fw) //(1) | release_firmware
| kfree(fw) //(2)
The firmware struct is deallocated in position (1) and deallocated
in position (2) again.
The crash trace triggered by POC is like below:
BUG: KASAN: double-free or invalid-free in fw_dnld_over
Call Trace:
kfree
fw_dnld_over
nfcmrvl_nci_unregister_dev
nci_uart_tty_close
tty_ldisc_kill
tty_ldisc_hangup
__tty_hangup.part.0
tty_release
...
What's more, there are also use-after-free and null-ptr-deref bugs
in nfcmrvl_fw_dnld_start. If we deallocate firmware struct, gpio or
set null to the members of priv->fw_dnld in nfcmrvl_nci_unregister_dev,
then, we dereference firmware, gpio or the members of priv->fw_dnld in
nfcmrvl_fw_dnld_start, the UAF or NPD bugs will happen.
This patch reorders destructive operations after nci_unregister_device
in order to synchronize between cleanup routine and firmware download
routine.
The nci_unregister_device is well synchronized. If the device is
detaching, the firmware download routine will goto error. If firmware
download routine is executing, nci_unregister_device will wait until
firmware download routine is finished.

Based on DesignWare Ethernet QoS datasheet, we are seeing the limitation
of Split Header (SPH) feature is not supported for Ipv4 fragmented packet.
This SPH limitation will cause ping failure when the packets size exceed
the MTU size. For example, the issue happens once the basic ping packet
size is larger than the configured MTU size and the data is lost inside
the fragmented packet, replaced by zeros/corrupted values, and leads to
ping fail.
So, disable the Split Header for Intel platforms.
v2: Add fixes tag in commit message.

With some SFP modules, such as Finisar FCLF8522P2BTL, the PHY hardware
strapping defaults to 1000BaseX mode, but the kernel prefers to set them
for SGMII mode. When this happens and the PHY is soft reset, the BMSR
status register is updated, but this happens after the kernel has already
read the PHY abilities during probing. This results in support not being
detected for, and the PHY not advertising support for, 10 and 100 Mbps
modes, preventing the link from working with a non-gigabit link partner.
When the PHY is being configured for SGMII mode, call genphy_read_abilities
again in order to re-read the capabilities, and update the advertising
field accordingly.
