If it fails, the driver won't load, so there should be no need to

In section 4.5.1.5. Initialization, the step 4 may be skipped and
continue with the Capture Setup sequence, so if the capture has been
setup, there is no need to trigger the initial source change event, just
start decoding, and follow the dynamic resolution change flow if the
configured values do not match those parsed by the decoder.
And it won't fail the gstreamer pipeline.

The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue
behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.
This patch converts drivers/media/* from tasklet to BH workqueue.

syzkaller reported use-after-free in load_firmware_cb() [1].
The reason is because the module allocated a struct tuner in tuner_probe(),
and then the module initialization failed, the struct tuner was released.
A worker which created during module initialization accesses this struct
tuner later, it caused use-after-free.
The process is as follows:
task-6504 worker_thread
tuner_probe <= alloc dvb_frontend [2]
...
request_firmware_nowait <= create a worker
...
tuner_remove <= free dvb_frontend
...
request_firmware_work_func <= the firmware is ready
load_firmware_cb <= but now the dvb_frontend has been freed
To fix the issue, check the dvd_frontend in load_firmware_cb(), if it is
null, report a warning and just return.

For iMX8QXP and iMX8QM, add bypass clocks and register some of the LVDS
clocks with imx_clk_scu2 as the parent needs to explicitly set.
In order to make sure MIPI DSI works well after suspend/resume, the LVDS
pixel and phy clocks must be initialized before the MIPI tx_esacpe
and rx_escape clocks. LVDS phy, LVDS pixel, tx_escape, and rx_esacpe are all
on the same MSLICE. They all share the same clock parent. So, setting the
parent source or rate affects all of these clocks. In the LVDS use case the
MIPI tx_escape and rx_escape are not saved and restored. So, LVDS works for
either clock initialization order. For MIPI case, LVDS must be initialized first.

On the i.MX8M*, the TF-A exposes a SiP (Silicon Provider) service
for DDR frequency scaling. The imx8m-ddrc-devfreq driver calls the
SiP and then does clk_set_parent on the DDR muxes to synchronize
the clock tree.
since commit 936c383673 ("clk: imx: fix composite peripheral flags"),
these TF-A managed muxes have SET_PARENT_GATE set, which results
in imx8m-ddrc-devfreq's clk_set_parent after SiP failing with -EBUSY:
clk_set_parent(dram_apb_src, sys1_pll_40m);(busfreq-imx8mq.c)
commit 926bf91248
("clk: imx8m: fix clock tree update of TF-A managed clocks") adds this
method and enables 8mm, 8mn and 8mq. i.MX8MP also needs it.
This is safe to do, because updating the Linux clock tree to reflect
reality will always be glitch-free.
Another reason to this patch is that powersave image BT music
requires dram to be 400MTS, so clk_set_parent(dram_alt_src,
sys1_pll_800m); is required. Without this patch, it will not succeed.

The clk_set_parent for "enet1_ref_sel" and "enet2_ref_sel" are
incorrect, therefore the original requirements to have "enet_clk_ref" as

Only "enet[1,2]_ref_125m" "enet[1,2]_ref_pad" are possible parents for
"enet1_ref_sel" and "enet2_ref_sel".
This was observed as a regression using a custom device tree which was
expecting this default config.
This can be fixed at the device tree level but having a default config

QCS8550 is derived from SM8550. The difference between SM8550 and
QCS8550 is QCS8550 doesn't have modem RF system. QCS8550 is mainly used
in IoT products.
QCS8550 firmware has different memory map compared to SM8550.
The memory map will be runtime added through bootloader.
There are 3 types of reserved memory regions here:
1. Firmware related regions which aren't shared with kernel.
The device tree source in kernel doesn't need to have node to indicate
the firmware related reserved information. Bootloader converys the
information by updating devicetree at runtime.
This will be described as: UEFI saves the physical address of the
UEFI System Table to dts file's chosen node. Kernel read this table and
add reserved memory regions to efi config table. Current reserved memory
region may have reserved region which was not yet used, release note of
the firmware have such kind of information.
2. Firmware related memory regions which are shared with Kernel
The device tree source in the kernel needs to include nodes that
indicate fimware-related shared information. A label name is suggested
because this type of shared information needs to be referenced by
specific drivers for handling purposes.
Unlike previous platforms, QCS8550 boots using EFI and describes
most reserved regions in the ESRT memory map. As a result, reserved
memory regions which aren't relevant to the kernel(like the hypervisor
region) don't need to be described in DT.
3. Remoteproc regions.
Remoteproc regions will be reserved and then assigned to subsystem
firmware later.
Here is a reserved memory map for this platform:

Add a node for the PMU module of the QCA6391 present on the RB5 board.
Assign its LDO power outputs to the existing Bluetooth module. Add a
node for the PCIe port to sm8250.dtsi and define the WLAN node on it in
the board's .dts and also make it consume the power outputs of the PMU.

Commit 8cab033628 ("clk: qcom: Add QCM2290 GPU clock controller driver")
adds the config CLK_QCM2290_GPUCC, which intends to select the support for
the QCM2290 Global Clock Controller. It however selects the non-existing
config CLK_QCM2290_GCC, whereas the config for the QCM2290 Global Clock
Controller is named QCM_GCC_2290.
Adjust the config to the intended one.

Enable the secure QFPROM driver used by Qualcomm QDU1000
platform to read the secure qfprom region allowing LLCC driver
to get the DDR channel configuration.
Currently, LLCC is the only user of secure QFPROM, and hence
setting CONFIG_NVMEM_QCOM_SEC_QFPROM as module to the convenience
of LLCC module.

varying between platforms. Switch to the new format to ensure
