[ Upstream commit 7e7e1541c91615e9950d0b96bcd1806d297e970e ]
REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on REGMAP" to "select REGMAP".

[ Upstream commit 0331b1b0ba65376ecf1c69414aa7696fef0930cb ]
After using the built-in UEFI hardware diagnostics to compare
the measured battery temperature, i noticed that the temperature
is actually expressed in tenth degree kelvin, similar to the
SBS-Data standard. For example, a value of 2992 is displayed as
26 degrees celsius.
Fix the scaling so that the correct values are being displayed.
Tested on a Dell Inspiron 3505.

[ Upstream commit 288b3271d920c9ba949c3bab0f749f4cecc70e09 ]
When the sd driver revalidates host-managed SMR disks, it calls
disk_set_zoned() which changes the zone_write_granularity attribute value
to the logical block size regardless of the device type. After that, the sd
driver overwrites the value in sd_zbc_read_zone() with the physical block
size, since ZBC/ZAC requires this for host-managed disks. Between the calls
to disk_set_zoned() and sd_zbc_read_zone(), there exists a window where the
attribute shows the logical block size as the zone_write_granularity value,
which is wrong for host-managed disks. The duration of the window is from
20ms to 200ms, depending on report zone command execution time.
To avoid the wrong zone_write_granularity value between disk_set_zoned()
and sd_zbc_read_zone(), modify the value not in sd_zbc_read_zone() but
just after disk_set_zoned() call.

[ Upstream commit bfa659177dcba48cf13f2bd88c1972f12a60bf1c ]
The firmware only supports Logical Disk IDs up to 240 and LD ID 255 (0xFF)
is reserved for deleted LDs. However, in some cases, firmware was assigning
LD ID 254 (0xFE) to deleted LDs and this was causing the driver to mark the
wrong disk as deleted. This in turn caused the wrong disk device to be
taken offline by the SCSI midlayer.
To address this issue, limit the LD ID range from 255 to 240. This ensures
the deleted LD ID is properly identified and removed by the driver without
accidently deleting any valid LDs.

[ Upstream commit 193250ace270fecd586dd2d0dfbd9cbd2ade977f ]
Fix data corruption issue with SerDes connected PHYs operating at 1.25
Gbps speed where we could previously observe about 30% packet loss while
the bad packet counter was increasing.
As almost all boards with MediaTek MT7622 or MT7986 use either the MT7531
switch IC operating at 3.125Gbps SerDes rate or single-port PHYs using
rate-adaptation to 2500Base-X mode, this issue only got exposed now when
we started trying to use SFP modules operating with 1.25 Gbps with the
BananaPi R3 board.
The fix is to set bit 12 which disables the RX FIFO clear function when
setting up MAC MCR, MediaTek SDK did the same change stating:
"If without this patch, kernel might receive invalid packets that are
corrupted by GMAC."[1]

[ Upstream commit a9334b702a03b693f54ebd3b98f67bf722b74870 ]
When MAC is not support PMT, driver will check PHY's WoL capability
and set device wakeup capability in stmmac_init_phy(). We can enable
the WoL through ethtool, the driver would enable the device wake up
flag. Now the device_may_wakeup() return true.
But if there is a way which enable the PHY's WoL capability derectly,
like in BIOS. The driver would not know the enable thing and would not
set the device wake up flag. The phy_suspend may failed like this:
[ 32.409063] PM: dpm_run_callback(): mdio_bus_phy_suspend+0x0/0x50 returns -16
[ 32.409065] PM: Device stmmac-1:00 failed to suspend: error -16
[ 32.409067] PM: Some devices failed to suspend, or early wake event detected
Add to set the device wakeup enable flag according to the get_wol
function result in PHY can fix the error in this scene.

The csum flag of IPsec packet are set repeatedly. Therefore, the csum
flag set of IPsec and non-IPsec packet need to be distinguished.
As the ipv6 header does not have a csum field, so l3-csum flag is not
required to be set for ipv6 case.
L4-csum flag include the tcp csum flag and udp csum flag, we shouldn't
set the udp and tcp csum flag at the same time for one packet, should
set l4-csum flag according to the transport layer is tcp or udp.

[ Upstream commit 84cba1840e68430325ac133a11be06bfb2f7acd8 ]
ice_get_module_eeprom() is broken since commit e9c9692c8a81 ("ice:
Reimplement module reads used by ethtool") In this refactor,
ice_get_module_eeprom() reads the eeprom in blocks of size 8.
But the condition that should protect the buffer overflow
ignores the last block. The last block always contains zeros.
Bug uncovered by ethtool upstream commit 9538f384b535
("netlink: eeprom: Defer page requests to individual parsers")
After this commit, ethtool reads a block with length = 1;
to read the SFF-8024 identifier value.

from the MAC driver
[ Upstream commit e57cf3639c323eeed05d3725fd82f91b349adca8 ]
Move the LAN7800 internal phy (phy ID 0x0007c132) specific register
accesses to the phy driver (microchip.c).
Fix the error reported by Enguerrand de Ribaucourt in December 2022,
"Some operations during the cable switch workaround modify the register
LAN88XX_INT_MASK of the PHY. However, this register is specific to the
LAN8835 PHY. For instance, if a DP8322I PHY is connected to the LAN7801,
that register (0x19), corresponds to the LED and MAC address
configuration, resulting in unapropriate behavior."
I did not test with the DP8322I PHY, but I tested with an EVB-LAN7800
with the internal PHY.

is a number based on the port chip port.

[ Upstream commit f99e6d7c4ed3be2531bd576425a5bd07fb133bd7 ]
While bringing hardware up we should perform a full reset including the
switch bit (BGMAC_BCMA_IOCTL_SW_RESET aka SICF_SWRST). It's what
specification says and what reference driver does.
This seems to be critical for the BCM5358. Without this hardware doesn't
get initialized properly and doesn't seem to transmit or receive any
packets.
Originally bgmac was calling bgmac_chip_reset() before setting
"has_robosw" property which resulted in expected behaviour. That has
changed as a side effect of adding platform device support which
regressed BCM5358 support.

[ Upstream commit 14e591a1930c2790fe862af5b01ee3ca587f752f ]
We now have some eDP+DSI dual panel systems floating around
where the DSI panel is the secondary LFP and thus needs to
consult "panel type 2" in VBT in order to locate all the
other panel type dependant stuff correctly.
To that end we need to pass in the devdata to
intel_bios_init_panel_late(), otherwise it'll just assume
we want the primary panel type. So let's try to just populate
the vbt.ports[] stuff and encoder->devdata for icl+ DSI
panels as well.
We can't do this on older platforms as there we risk a DSI
port aliasing with a HDMI/DP port, which is a totally legal
thing as the DSI ports live in their own little parallel
universe.

[ Upstream commit 3f9ffce5765d68775163b8b134c4d7f156b48eec ]
Lots of ADL machines out there with bogus VBTs that declare
two eDP child devices. In order for those to work we need to
figure out which power sequencer to use before we try the EDID
read. So let's do the panel VBT init early if we can, falling
back to the post-EDID init otherwise.
The post-EDID init panel_type=0xff approach of assuming the
power sequencer should already be enabled doesn't really work
with multiple eDP panels, and currently we just end up using
the same power sequencer for both eDP ports, which at least
confuses the wakeref tracking, and potentially also causes us
to toggle the VDD for the panel when we should not.

Introduce a place where we can initialize connector->panel
after it's been allocated. We already have a intel_panel_init()
so had to get creative with the name and came up with
intel_panel_init_alloc().

[ Upstream commit 1ddc7618294084fff8d673217a9479550990ee84 ]
state_lock, the spinlock type is meant to protect race against concurrent
MHI state transitions. In mhi_ep_set_m0_state(), while the state_lock is
being held, the channels are resumed in mhi_ep_resume_channels() if the
previous state was M3. This causes sleeping in atomic bug, since
mhi_ep_resume_channels() use mutex internally.
Since the state_lock is supposed to be held throughout the state change,
it is not ideal to drop the lock before calling mhi_ep_resume_channels().
So to fix this issue, let's change the type of state_lock to mutex. This
would also allow holding the lock throughout all state transitions thereby
avoiding any potential race.

[ Upstream commit 47a1dcaea07367c84238e71c08244ae3ed48c1cc ]
During graceful shutdown scenario, host will issue MHI RESET to the
endpoint device before initiating shutdown. In that case, it makes sense
to completely power down the MHI stack as sooner or later the access to
MMIO registers will be prohibited. Also, the stack needs to be powered
up in the case of SYS_ERR to recover the device.

commit 1c5d4221240a233df2440fe75c881465cdf8da07 upstream.
The default maximum data buffer size for this interface is UHID_DATA_MAX
(4k). When data buffers are being processed, ensure this value is used
when ensuring the sanity, rather than a value between the user provided
value and HID_MAX_BUFFER_SIZE (16k).

commit b1a37ed00d7908a991c1d0f18a8cba3c2aa99bdc upstream.
Presently, when a report is processed, its proposed size, provided by
the user of the API (as Report Size * Report Count) is compared against
the subsystem default HID_MAX_BUFFER_SIZE (16k). However, some
low-level HID drivers allocate a reduced amount of memory to their
buffers (e.g. UHID only allocates UHID_DATA_MAX (4k) buffers), rending
this check inadequate in some cases.
In these circumstances, if the received report ends up being smaller
than the proposed report size, the remainder of the buffer is zeroed.
That is, the space between sizeof(csize) (size of the current report)
and the rsize (size proposed i.e. Report Size * Report Count), which can
be handled up to HID_MAX_BUFFER_SIZE (16k). Meaning that memset()
shoots straight past the end of the buffer boundary and starts zeroing
out in-use values, often resulting in calamity.
This patch introduces a new variable into 'struct hid_ll_driver' where
individual low-level drivers can over-ride the default maximum value of
HID_MAX_BUFFER_SIZE (16k) with something more sympathetic to the
interface.

commit d17789edd6a8270c38459e592ee536a84c6202db upstream.
To last 2 parameters to cfg80211_get_bss() should be of
the enum ieee80211_bss_type resp. enum ieee80211_privacy types,
which WLAN_CAPABILITY_ESS very much is not.
Fix both cfg80211_get_bss() calls in ioctl_cfg80211.c to pass
the right parameters.
Note that the second call was already somewhat fixed by commenting
out WLAN_CAPABILITY_ESS and passing in 0 instead. This was still
not entirely correct though since that would limit returned
BSS-es to ESS type BSS-es with privacy on.

commit 05cbcc415c9b8c8bc4f9a09f8e03610a89042f03 upstream.
There are 2 issues with the key-store index handling
1. The non WEP key stores can store keys with indexes 0 - BIP_MAX_KEYID,
this means that they should be an array with BIP_MAX_KEYID + 1
entries. But some of the arrays where just BIP_MAX_KEYID entries
big. While one other array was hardcoded to a size of 6 entries,
instead of using the BIP_MAX_KEYID define.
2. The rtw_cfg80211_set_encryption() and wpa_set_encryption() functions
index check where checking that the passed in key-index would fit
inside both the WEP key store (which only has 4 entries) as well as
in the non WEP key stores. This breaks any attempts to set non WEP
keys with index 4 or 5.
Issue 2. specifically breaks wifi connection with some access points
which advertise PMF support. Without this fix connecting to these
access points fails with the following wpa_supplicant messages:
nl80211: kernel reports: key addition failed
wlan0: WPA: Failed to configure IGTK to the driver
wlan0: RSN: Failed to configure IGTK
wlan0: CTRL-EVENT-DISCONNECTED bssid=... reason=1 locally_generated=1
Fix 1. by using the right size for the key-stores. After this 2. can
safely be fixed by checking the right max-index value depending on the
used algorithm, fixing wifi not working with some PMF capable APs.

commit 6153c44392b04ff2da1e9aa82ba87da9ab9a0fc1 upstream.
A recent commit moved enabling of runtime PM from adreno_gpu_init() to
adreno_load_gpu() (called on first open()), which means that unbind()
may now be called with runtime PM disabled in case the device was never
opened in between.
Make sure to only forcibly suspend and disable runtime PM at unbind() in
case runtime PM has been enabled to prevent a disable count imbalance.
This specifically avoids leaving runtime PM disabled when the device
is later opened after a successful bind:

commit e5eef23e267c72521d81f23f7f82d1f523d4a253 upstream.
The EDID of an HDR display defines EOTFs that are supported
by the display and can be set in the HDR metadata infoframe.
Userspace is expected to read the EDID and set an appropriate
HDR_OUTPUT_METADATA.
In drm_parse_hdr_metadata_block the kernel reads the supported
EOTFs from the EDID and stores them in the
drm_connector->hdr_sink_metadata. While doing so it also
filters the EOTFs to the EOTFs the kernel knows about.
When an HDR_OUTPUT_METADATA is set it then checks to
make sure the EOTF is a supported EOTF. In cases where
the kernel doesn't know about a new EOTF this check will
fail, even if the EDID advertises support.
Since it is expected that userspace reads the EDID to understand
what the display supports it doesn't make sense for DRM to block
an HDR_OUTPUT_METADATA if it contains an EOTF the kernel doesn't
understand.
This comes with the added benefit of future-proofing metadata
support. If the spec defines a new EOTF there is no need to
update DRM and an compositor can immediately make use of it.
