- To align the naming rule
- To reduce the code size

Rename all "mtk_drm_crtc" to "mtk_crtc" due to the following benefits:
- Lower the matches when searching the native drm_crtc* codes

In the case where `conn_routes` is true we allocate an extra slot in
the `ddp_comp` array but mtk_drm_crtc_create() never seemed to
initialize it in the test case I ran. For me, this caused a later
crash when we looped through the array in mtk_drm_crtc_mode_valid().
This showed up for me when I booted with `slub_debug=FZPUA` which
poisons the memory initially. Without `slub_debug` I couldn't
reproduce, presumably because the later code handles the value being
NULL and in most cases (not guaranteed in all cases) the memory the
allocator returned started out as 0.
It really doesn't hurt to initialize the array with devm_kcalloc()
since the array is small and the overhead of initting a handful of
elements to 0 is small. In general initting memory to zero is a safer
practice and usually it's suggested to only use the non-initting alloc
functions if you really need to.
Let's switch the function to use an allocation function that zeros the
memory. For me, this avoids the crash.

Add a check to mtk_drm_gem_init if we attempt to allocate a GEM object
of 0 bytes. Currently, no such check exists and the kernel will panic if
a userspace application attempts to allocate a 0x0 GBM buffer.
Tested by attempting to allocate a 0x0 GBM buffer on an MT8188 and
verifying that we now return EINVAL.

mtk_hdmi_ddc_probe()
A wrapper function is available since the commit 890cc39a8799
("drivers: provide devm_platform_get_and_ioremap_resource()").
Thus reuse existing functionality instead of keeping duplicate

The -Woverride-init warn about code that may be intentional or not,
but the inintentional ones tend to be real bugs, so there is a bit of
disagreement on whether this warning option should be enabled by default
and we have multiple settings in scripts/Makefile.extrawarn as well as
individual subsystems.
Older versions of clang only supported -Wno-initializer-overrides with
the same meaning as gcc's -Woverride-init, though all supported versions
now work with both. Because of this difference, an earlier cleanup of
mine accidentally turned the clang warning off for W=1 builds and only
left it on for W=2, while it's still enabled for gcc with W=1.
There is also one driver that only turns the warning off for newer
versions of gcc but not other compilers, and some but not all the
Makefiles still use a cc-disable-warning conditional that is no
longer needed with supported compilers here.
Address all of the above by removing the special cases for clang
and always turning the warning off unconditionally where it got
in the way, using the syntax that is supported by both compilers.

The two major fixes are the sg teardown race and a core error leg

On devices that support DASH, the current code in the "rtl_loop_wait" function
raises false alarms when DASH is disabled. This occurs because the function
attempts to wait for the DASH firmware to be ready, even though it's not
relevant in this case.
r8169 0000:0c:00.0 eth0: RTL8168ep/8111ep, 38:7c:76:49:08:d9, XID 502, IRQ 86
r8169 0000:0c:00.0 eth0: jumbo features [frames: 9194 bytes, tx checksumming: ko]
r8169 0000:0c:00.0 eth0: DASH disabled
...
r8169 0000:0c:00.0 eth0: rtl_ep_ocp_read_cond == 0 (loop: 30, delay: 10000).
This patch modifies the driver start/stop functions to skip checking the DASH
firmware status when DASH is explicitly disabled. This prevents unnecessary
delays and false alarms.
The patch has been tested on several ThinkStation P8/PX workstations.

This reverts commit 29a43dc130ce65d365a8ea9e1cc4bc51005a353e.
29a43dc130ce ("PCI: Mark LSI FW643 to avoid bus reset") by Edmund was based
on the assumption that the LSI / Agere FW643 has a defect such that it
can't recover after a Secondary Bus Reset (SBR).
But Takashi Sakamoto reported that SBR works fine on this same FW643 device
in an AMD Ryzen 5 2400G system, so apparently there is some other aspect of
Edmund's system that accounts for the issue.
The down side of 29a43dc130ce is that when the FW643 is assigned to a VM,
avoiding the SBR means we leak data out of the VM.
Revert 29a43dc130ce until we figure out a better solution. In the
meantime, we can use the sysfs "reset_method" interface to restrict the
available reset methods.

During system shutdown, the mlxbf_gige driver's shutdown() is always executed.
However, the driver's stop() method will only execute if networking interface
configuration logic within the Linux distribution has been setup to do so.
If shutdown() executes but stop() does not execute, NAPI remains enabled
and this can lead to an exception if NAPI is scheduled while the hardware
interface has only been partially deinitialized.
The networking interface managed by the mlxbf_gige driver must be properly
stopped during system shutdown so that IFF_UP is cleared, the hardware
interface is put into a clean state, and NAPI is fully deinitialized.

Add infra to support card power and energy attributes through channel 0.
Package attributes will be now exposed through channel 1 rather than
channel 0 as shown below.
Channel 0 i.e power1/energy1_xxx used for card and
channel 1 i.e power2/energy2_xxx used for package power,energy attributes.
power1/curr1_crit and in0_input are moved to channel 1, i.e.
power2/curr2_crit and in1_input as these are available for package only.
This would be needed for future platforms where they might be
separate registers for package and card power and energy.
Each discrete GPU supported by Xe driver, would have a directory in
/sys/class/hwmon/ with multiple channels under it.
Each channel would have attributes for power, energy etc.
Ex: /sys/class/hwmon/hwmon2/power1_max
/power1_label
/energy1_input
/energy1_label
Attributes will have a label to get more description of it.
Labelling is as below.
power1_label/energy1_label - "card",
power2_label/energy2_label - "pkg".
v2: Fix checkpatch errors.
v3:

The WCN6855 firmware on the Lenovo ThinkPad X13s expects the Bluetooth
device address in big-endian order when setting it using the
EDL_WRITE_BD_ADDR_OPCODE command.
Presumably, this is the case for all non-ROME devices which all use the
EDL_WRITE_BD_ADDR_OPCODE command for this (unlike the ROME devices which
use a different command and expect the address in little-endian order).
Reverse the little-endian address before setting it to make sure that
the address can be configured using tools like btmgmt or using the
'local-bd-address' devicetree property.
Note that this can potentially break systems with boot firmware which
has started relying on the broken behaviour and is incorrectly passing
the address via devicetree in big-endian order.
The only device affected by this should be the WCN3991 used in some
Chromebooks. As ChromeOS updates the kernel and devicetree in lockstep,
the new 'qcom,local-bd-address-broken' property can be used to determine
if the firmware is buggy so that the underlying driver bug can be fixed
without breaking backwards compatibility.
Set the HCI_QUIRK_BDADDR_PROPERTY_BROKEN quirk for such platforms so
that the address is reversed when parsing the address property.

This reverts commit 7dcd3e014aa7faeeaf4047190b22d8a19a0db696.
Qualcomm Bluetooth controllers like WCN6855 do not have persistent
storage for the Bluetooth address and must therefore start as
unconfigured to allow the user to set a valid address unless one has
been provided by the boot firmware in the devicetree.
A recent change snuck into v6.8-rc7 and incorrectly started marking the
default (non-unique) address as valid. This specifically also breaks the
Bluetooth setup for some user of the Lenovo ThinkPad X13s.
Note that this is the second time Qualcomm breaks the driver this way
and that this was fixed last year by commit 6945795bc81a ("Bluetooth:
fix use-bdaddr-property quirk"), which also has some further details.

If the SPI data size is smaller than FIFO, it operates in PIO mode,
and if it is larger than FIFO size, it oerates in DMA mode.
If the SPI data size is equal to fifo, it operates in PIO mode and it is
separated to 2 transfers. To prevent it, it must operate in DMA mode
from the case where the data size and the fifo size are the same.
