The current check on val always results in true and so the
call to sii1133_update_adcsens never gets called. Fix this check
so it returns with -EINVAL only when val is not zero and not one.

Debugfs support to do hardware warm reset with WMI command
WMI_PDEV_PARAM_PDEV_RESET for 10.4 and 10.2.4(if wmi
service is enabled in the firmware for backward compatibility).
This change is purely for debugging purpose when hardware hangs/mutes.
This hardware reset won't affect the connectivity but there will be small
pause in data traffic. Here we are doing BB/MAC level reset and hence
whenever the BB/MAC watchdog is triggered, it does a hardware_chip_reset.
So the target will be in the active state.
Below command used to warm reset the hardware.

WCN3990 transmits management frames via WMI
with reference. Currently, with the management
tx completion not being handled, these frames are
not getting freed even after the transmission status
is returned by the firmware.
The transmitted management frames should be freed
when the firmware sends the over-the-air tx status of
the corresponding management frames.
Handle the wmi mgmt tx completion event and free
the corresponding management frame.

The tx completion of multiple mgmt frames can be bundled
in a single event and sent by the firmware to host, if this
capability is not disabled explicitly by the host. If the host
cannot handle the bundled mgmt tx completion, this capability
support needs to be disabled in the wmi init cmd, sent to the firmware.
Add the host capability indication flag in the wmi ready command,
to let firmware know the features supported by the host driver.
This field is ignored if it is not supported by firmware.
Set the host capability indication flag(i.e. host_capab) to zero,
for disabling the support of bundle mgmt tx completion. This will
indicate the firmware to send completion event for every mgmt tx
completion, instead of bundling them together and sending in a single
event.

There are two modes in which DEVSLP can be entered. The OS initiated or
hardware autonomous.
In hardware autonomous mode, BIOS configures the AHCI controller and the
device to enable DEVSLP. But they may not be ideal for all cases. So in
this case, OS should be able to reconfigure DEVSLP register.
Currently if the DEVSLP is already enabled, we can't set again as it will
simply return. There are some systems where the firmware is setting high
DITO by default, in this case we can't modify here to correct settings.
With the default in several seconds, we are not able to transition to
DEVSLP.
This change will allow reconfiguration of devslp register if DITO is
different.

We have seen that on some platforms, SATA device never show any DEVSLP
residency. This prevent power gating of SATA IP, which prevent system
to transition to low power mode in systems with SLP_S0 aka modern
standby systems. The PHY logic is off only in DEVSLP not in slumber.

The metadata low watermark threshold is set by the kernel. But the
kernel depends on userspace to extend the thinpool metadata device when
the threshold is crossed.
Since the metadata low watermark threshold is not visible to userspace,
upon receiving an event, userspace cannot tell that the kernel wants the
metadata device extended, instead of some other eventing condition.
Making it visible (but not settable) enables userspace to affirmatively
know the kernel is asking for a metadata device extension, by comparing
metadata_low_watermark against nr_free_blocks_metadata, also reported in
status.
Current solutions like dmeventd have their own thresholds for extending
the data and metadata devices, and both devices are checked against
their thresholds on each event. This lessens the value of the kernel-set
threshold, since userspace will either extend the metadata device sooner,
when receiving another event; or will receive the metadata lowater event
and do nothing, if dmeventd's threshold is less than the kernel's.
(This second case is dangerous. The metadata lowater event will not be
re-sent, so no further event will be generated before the metadata
device is out if space, unless some other event causes userspace to
recheck its thresholds.)

One of the requirement for modern x86 system to enter lowest power mode
(SLP_S0) is SATA IP block to be off. This is true even during when
platform is suspended to idle and not only in opportunistic (runtime)
suspend.
Several of these system don't have traditional ACPI S3, so it is
important that they enter SLP_S0 state, to avoid draining battery even
during suspend. So it is important that out of the box Linux installation
reach this state.
SATA IP block doesn't get turned off till SATA is in DEVSLP mode. Here
user has to either use scsi-host sysfs or tools like powertop to set
the sata-host link_power_management_policy to min_power.
This change sets by default link power management policy to min_power
with partial (preferred) or slumber support on idle for some platforms.
To avoid regressions, the following conditions are used:
- User didn't override the policy from module parameter
- The kernel config is already set to use med_power_with_dipm or deeper
- System is a SLP_S0 capable using ACPI low power idle flag
This combination will make sure that systems are fairly recent and
since getting shipped with SLP_S0 support, the DEVSLP function
is already validated.

Currently when min_power policy is selected, the partial low power state

Add a new policy which still enable DEVSLP but also try to enter partial
low power state. This policy is presented as "min_power_with_partial".
For information the difference between partial and slumber
Partial – PHY logic is powered up, and in a reduced power state. The link
PM exit latency to active state maximum is 10 ns.
Slumber – PHY logic is powered up, and in a reduced power state. The link
PM exit latency to active state maximum is 10 ms.
Devslp – PHY logic is powered down. The link PM exit latency from this
state to active state maximum is 20 ms, unless otherwise specified by

The em28xx driver never touched the EM2874 register bits that control
the transport stream packet filters, leaving them at whatever default
the firmware has set. E.g. the Pinnacle 290e disables them by default,
while the Hauppauge WinTV dualHD enables discarding NULL packets by
default.
However, some applications require NULL packets, e.g. to determine the
load in DOCSIS segments, so discarding NULL packets is undesired for
such applications.
This patch simply extends the bit mask when starting or stopping the
transport stream packet capture, so that the filter bits are cleared.
It has been verified that this makes the Hauppauge WinTV dualHD pass
an unfiltered DVB-C stream including NULL packets, which it didn't
before.

To be able to better support different mmci variants, we need to be able to
use variant specific callbacks, rather than continue to sprinkle the code
with additional variant data. To move in this direction, let's add an
optional ->init() callback to the variant data struct, which variants shall
use to assign the mmci_host_ops pointer.
Using an ->init() callback enables us to partition the code between
different files. To allow separate mmci variant files to implement the
variant specifics, let's also move the definition of the struct
variant_data to the common mmci header file.

Tegra SDHCI controllers require the SDHCI clock divider to be configured
to divide the clock by two in DDR50/52 modes. Incorrectly configured
clock divider results in corrupted data.
Prevent the possibility of incorrectly calculating the divider value due
to clock rate rounding or low parent clock frequency by not assigning
host->max_clk to clk_get_rate() on tegra_sdhci_set_clock().
See the comments for further details.

Found and reported by kbuild test robot:
Message ID: <201805052003.MC007f9h%fengguang.wu@intel.com>
and holding an address of an empty struct in .driver.pm does no harm
when CONFIG_PM_SLEEP is not defined.

Friio device contains "gl861" bridge and "tc90522" demod,
for which the separate drivers are already in the kernel.
But friio driver was monolithic and did not use them,
practically copying those features.
This patch decomposes friio driver into sub drivers and
re-uses existing ones, thus reduces some code.
It adds some features to gl861,
to support the friio-specific init/config of the devices
and implement i2c communications to the tuner via demod
with USB vendor requests.

Remove a chunk of unused code from drm_crtc.c, namely
dpu_crtc_res_add, dpu_crtc_res_get, dpu_crtc_res_put
and associated static functions.
Also zap dpu_crtc_event_queue(), helper functions
and members.
