Non-display now calls the intel_fsb_freq() and intel_mem_freq()

Update intel_dp_compute_config_limits() to use a minimum of
30 bits per pixel when the connector is in HDR mode
(specifically, when EOTF is SMPTE ST2084), aligning with HDR
display requirements.
To support this, the function now takes a drm_connector_state
instead of an intel_connector, and the required updates are
made in all call sites, including MST handling.
This ensures sufficient bitdepth for HDR content to avoid
banding.
If the required bandwidth for 30 bpp cannot be supported,
the driver will either fall back to DSC or reject the mode
during atomic check if DSC is not supported.

The ISR calls dev_pm_opp_find_bw_ceil(), which can return EINVAL, ERANGE
or ENODEV, and if that one fails with ERANGE, then it tries again with
floor dev_pm_opp_find_bw_floor().
In theory, following error paths are possible:
1. First dev_pm_opp_find_bw_ceil() failed with an error different than
ERANGE,
2. Any error from second dev_pm_opp_find_bw_floor().
However in practice this would mean that there are no suitable OPPs at
all, which is already being checked in the drivers probe() function.
This is impossible condition.
Relying however in the interrupt handler bwmon_intr_thread() on
preconditions checked in probe() is not easy to follow from code
readability and is very difficult to handle in static analysis, thus
let's make the code just obvious to silence warning reported by Smatch:

ESI/MSI is a performance optimization feature that provides dedicated
interrupts per MCQ hardware queue. This is optional feature and UFS MCQ
should work with and without ESI feature.
Commit e46a28cea2 ("scsi: ufs: qcom: Remove the MSI descriptor abuse")
brings a regression in ESI (Enhanced System Interrupt) configuration that
causes a null pointer dereference when Platform MSI allocation fails.
The issue occurs in when platform_device_msi_init_and_alloc_irqs() in
ufs_qcom_config_esi() fails (returns -EINVAL) but the current code uses
__free() macro for automatic cleanup free MSI resources that were never
successfully allocated.
Unable to handle kernel NULL pointer dereference at virtual

Fix by restructuring the ESI configuration to try MSI allocation first,

While the current code is perfectly fine (because we verify that the
device is directly attached before using attached_phy to index the
pm8001_ha->phy array), let's use the pm80xx_get_local_phy_id() helper
anyway, to reduce the chance that someone will copy paste this pattern
to other parts of the driver.
Note that in this specific case, we still need to keep the check that
the device is not behind an expander, because we do not want to clear
attached_phy of the expander if a device behind the expander disappears
(as that would disable all the other devices behind the expander).
However, if it is the expander itself that disappears, attached_phy will
be cleared, just like it would for any other directly attached device.

index 28 is out of range for type 'pm8001_phy [16]'

For a direct attached device, attached_phy contains the local phy id.
For a device behind an expander, attached_phy contains the remote phy
id, not the local phy id.
I.e. while pm8001_ha will have pm8001_ha->chip->n_phy local phys, for a
device behind an expander, attached_phy can be much larger than
pm8001_ha->chip->n_phy (depending on the amount of phys of the
expander).
E.g. on my system pm8001_ha has 8 phys with phy ids 0-7. One of the
ports has an expander connected. The expander has 31 phys with phy ids
0-30.
The pm8001_ha->phy array only contains the phys of the HBA. It does not
contain the phys of the expander. Thus, it is wrong to use attached_phy
to index the pm8001_ha->phy array for a device behind an expander.
Thus, we can only clear phy_attached for devices that are directly
attached.

wake state on this interrupt as appropriate, depending on the
device_set_wakeup_enable() state. device_set_wakeup_enable() does not

The core ethtool API validates the WoL options passed from userspace
against the support which the driver reports from its get_wol() method,
returning EINVAL if an unsupported mode is requested.
Therefore, there is no need for stmmac to implement its own validation.
Remove this unnecessary code.
See ethnl_set_wol() in net/ethtool/wol.c and ethtool_set_wol() in
net/ethtool/ioctl.c.

mac_device_info->pmt is only ever written, nothing reads it. Remove
this struct member.

Phylink will check whether the MAC supports the LPI methods in
struct phylink_mac_ops, and return -EOPNOTSUPP if the LPI capabilities
are not provided. stmmac doesn't provide LPI capabilities if
priv->dma_cap.eee is not set.
Therefore, checking the state of priv->dma_cap.eee in the ethtool ops
and returning -EOPNOTSUPP is redundant - let phylink handle this.

When STA connects to AP with dot11MultiBSSIDImplemented set to true,
the layout of the TIM element's Partial Virtual Bitmap changes. Bits
1 to (2^n - 1) are used to indicate buffered group addressed frames
(e.g., broadcast/multicast) for non-transmitted BSSIDs. Fix the
interpretation of this field to ensure group addressed frames
are correctly received.

For non-transmitted connections, beacons are received from the
transmitted BSSID. Fix this to avoid missing beacon statistics.

Adjust TX wideband calibration from 1 to 2 loop gain settings.
This can reflect in better performance in 5 GHz medium-high
