Rename a local variable in teo_update() so that its purpose is better
reflected by its name and use one more local variable in the loop
over the CPU idle states in that function to make the code somewhat
easier to read.
No functional impact.

With global filtering, we only allow an event to be scheduled if its
filter settings exactly match those of any existing events, therefore
it is pointless to reapply the filter in that case. Much worse, though,
is that in doing that we trample the event type of counter 0 if it's
already active, and never touch the appropriate PMEVTYPERn so the new
event is likely not counting the right thing either. Don't do that.

The Elgato Cam Link 4K HDMI video capture card reports to support three
different pixel formats, where the first format depends on the connected
HDMI device.
```
$ v4l2-ctl -d /dev/video0 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
Type: Video Capture
[0]: 'NV12' (Y/CbCr 4:2:0)
Size: Discrete 3840x2160
Interval: Discrete 0.033s (29.970 fps)
[1]: 'NV12' (Y/CbCr 4:2:0)
Size: Discrete 3840x2160
Interval: Discrete 0.033s (29.970 fps)
[2]: 'YU12' (Planar YUV 4:2:0)
Size: Discrete 3840x2160
Interval: Discrete 0.033s (29.970 fps)
```
Changing the pixel format to anything besides the first pixel format
does not work:
```
$ v4l2-ctl -d /dev/video0 --try-fmt-video pixelformat=YU12
Format Video Capture:
Width/Height : 3840/2160
Pixel Format : 'NV12' (Y/CbCr 4:2:0)
Field : None
Bytes per Line : 3840
Size Image : 12441600
Colorspace : sRGB
Transfer Function : Rec. 709
YCbCr/HSV Encoding: Rec. 709
Quantization : Default (maps to Limited Range)
Flags :
```
User space applications like VLC might show an error message on the
terminal in that case:
```
libv4l2: error set_fmt gave us a different result than try_fmt!
```
Depending on the error handling of the user space applications, they
might display a distorted video, because they use the wrong pixel format
for decoding the stream.
The Elgato Cam Link 4K responds to the USB video probe
VS_PROBE_CONTROL/VS_COMMIT_CONTROL with a malformed data structure: The
second byte contains bFormatIndex (instead of being the second byte of
bmHint). The first byte is always zero. The third byte is always 1.
The firmware bug was reported to Elgato on 2020-12-01 and it was
forwarded by the support team to the developers as feature request.
There is no firmware update available since then. The latest firmware
for Elgato Cam Link 4K as of 2021-03-23 has MCU 20.02.19 and FPGA 67.
Therefore correct the malformed data structure for this device. The
change was successfully tested with VLC, OBS, and Chromium using
different pixel formats (YUYV, NV12, YU12), resolutions (3840x2160,
1920x1080), and frame rates (29.970 and 59.940 fps).

If an error occurs after a successful 'ioremap()' call, it must be undone
by a corresponding 'iounmap()' call, as already done in the remove
function.
Add a 'pf_sw_fail' label in the error handling path and add the missing
'iounmap()'.
While at it, also add a 'flr_fail' label in the error handling path and use
it to avoid some code duplication.

This allows m68k q40 systems to switch from the deprecated IDE subsystem
to libata.
Enhance the byte-swapping falconide and pata_falcon platform drivers to
accept an irq resource, for use on q40. Atari ST-DMA IRQ arrangements seem
to co-exist with q40 IRQ arrangements without too much mess.
The new IO resources were added solely for the purpose of making
request_region() reservations identical to those made by q40ide: these
regions aren't used for actual IO.

This allows m68k mac systems to switch from the deprecated IDE subsystem
to libata.
This was tested on my Quadra 630. I haven't tested it on my PowerBook 150
because I don't have a RAM adapter board for it. It appears that the
hardware I tested doesn't need macide_clear_irq() or macide_test_irq().
If it did, the generic driver would not have worked. It's possible that
those routines are needed for the PowerBook 150 but we can cross that
bridge if and when we come to it.
BTW, macide_clear_irq() appears to suffer from a race condition. The write
to the interrupt flags register could have unintended side effects as it
may alter other flag bits. Fortunately, all of the other bits are unused
by Linux. When tested on my Quadra 630, the assignment *ide_ifr &= ~0x20
was observed to have no effect on bit 5, so it may be redundant anyway.

If ucsi_init() fails for some reason (e.g. ucsi_register_port()
fails or general communication failure to the PPM), particularly at
any point after the GET_CAPABILITY command had been issued, this
results in unwinding the initialization and returning an error.
However the ucsi structure's ucsi_capability member retains its
current value, including likely a non-zero num_connectors.
And because ucsi_init() itself is done in a workqueue a UCSI
interface driver will be unaware that it failed and may think the
ucsi_register() call was completely successful. Later, if
ucsi_unregister() is called, due to this stale ucsi->cap value it
would try to access the items in the ucsi->connector array which
might not be in a proper state or not even allocated at all and
results in NULL or invalid pointer dereference.
Fix this by clearing the ucsi->cap value to 0 during the error
path of ucsi_init() in order to prevent a later ucsi_unregister()
from entering the connector cleanup loop.

The commit a390bef7db1f ("usb: gadget: fsl_mxc_udc: Remove the driver")
dropped the ARCH_MXC dependency from USB_FSL_USB2, leaving it depending
solely on FSL_SOC.
FSL_SOC is powerpc only; it was briefly available on ARM in 2014 but was
removed by commit cfd074ad8600 ("ARM: imx: temporarily remove
CONFIG_SOC_FSL from LS1021A"). Therefore the driver can no longer be
enabled on ARM platforms.
This appears to be a mistake as arm64's ARCH_LAYERSCAPE and arm32
SOC_LS1021A SoCs use this symbol. It's enabled in these defconfigs:
arch/arm/configs/imx_v6_v7_defconfig:CONFIG_USB_FSL_USB2=y
arch/arm/configs/multi_v7_defconfig:CONFIG_USB_FSL_USB2=y
arch/powerpc/configs/mgcoge_defconfig:CONFIG_USB_FSL_USB2=y
arch/powerpc/configs/mpc512x_defconfig:CONFIG_USB_FSL_USB2=y
To fix, expand the dependencies so USB_FSL_USB2 can be enabled on the
ARM platforms, and with COMPILE_TEST.

As LKP noticed the Sparse is not happy about strict type handling:

.../typec/tcpm/wcove.c:380:50: sparse: got restricted __le16 const [usertype] header

The arm64 entry code suffers from an annoying issue on taking
a NMI, as it sets PMR to a value that actually allows IRQs
to be acknowledged. This is done for consistency with other parts
of the code, and is in the process of being fixed. This shouldn't
be a problem, as we are not enabling interrupts whilst in NMI
context.
However, in the infortunate scenario that we took a spurious NMI
(retired before the read of IAR) *and* that there is an IRQ pending
at the same time, we'll ack the IRQ in NMI context. Too bad.
In order to avoid deadlocks while running something like perf,
teach the GICv3 driver about this situation: if we were in
a context where no interrupt should have fired, transiently
set PMR to a value that only allows NMIs before acking the pending
interrupt, and restore the original value after that.
This papers over the core issue for the time being, and makes
NMIs great again. Sort of.

Current shunt LSB values got reversed during in the
original driver commit.
So, correct the current shunt LSB values according to
the datasheet.
This caused reading slightly skewed current values.

TPS23861 has a configuration bit for setting of the
current shunt value used on the board.
Its bit 0 of the General Mask 1 register.
According to the datasheet bit values are:
0 for 255 mOhm (Default)
1 for 250 mOhm
So, configure the bit before registering the hwmon
device according to the value passed in the DTS or
default one if none is passed.
This caused potentially reading slightly skewed values
due to max current value being 1.02A when 250mOhm shunt
is used instead of 1.0A when 255mOhm is used.

Define the max register address the device supports.
This allows reading the whole register space via
regmap debugfs, without it only register 0x0 is visible.

CP2102N revision A01 (firmware version <= 1.0.4) has a buggy
flow-control implementation that uses the ulXonLimit instead of
ulFlowReplace field of the flow-control settings structure (erratum
CP2102N_E104).
A recent change that set the input software flow-control limits
incidentally broke RTS control for these devices when CRTSCTS is not set
as the new limits would always enable hardware flow control.
Fix this by explicitly disabling flow control for the buggy firmware
versions and only updating the input software flow-control limits when
IXOFF is requested. This makes sure that the terminal settings matches
the default zero ulXonLimit (ulFlowReplace) for these devices.

A problem was reported on CoachZ devices where the display wouldn't come
up, or it would be distorted. It turns out that the PLL code here wasn't
getting called once dsi_pll_10nm_vco_recalc_rate() started returning the
same exact frequency, down to the Hz, that the bootloader was setting
instead of 0 when the clk was registered with the clk framework.
After commit 001d8dc33875 ("drm/msm/dsi: remove temp data from global
pll structure") we use a hardcoded value for the parent clk frequency,
i.e. VCO_REF_CLK_RATE, and we also hardcode the value for FRAC_BITS,
instead of getting it from the config structure. This combination of
changes to the recalc function allows us to properly calculate the
frequency of the PLL regardless of whether or not the PLL has been
clk_prepare()d or clk_set_rate()d. That's a good improvement.
Unfortunately, this means that now we won't call down into the PLL clk
driver when we call clk_set_rate() because the frequency calculated in
the framework matches the frequency that is set in hardware. If the rate
is the same as what we want it should be OK to not call the set_rate PLL
op. The real problem is that the prepare op in this driver uses a
private struct member to stash away the vco frequency so that it can
call the set_rate op directly during prepare. Once the set_rate op is
never called because recalc_rate told us the rate is the same, we don't
set this private struct member before the prepare op runs, so we try to
call the set_rate function directly with a frequency of 0. This
effectively kills the PLL and configures it for a rate that won't work.
Calling set_rate from prepare is really quite bad and will confuse any
downstream clks about what the rate actually is of their parent. Fixing
that will be a rather large change though so we leave that to later.
For now, let's stash away the rate we calculate during recalc so that
the prepare op knows what frequency to set, instead of 0. This way
things keep working and the display can enable the PLL properly. In the
future, we should remove that code from the prepare op so that it
doesn't even try to call the set rate function.
