889fcd5832 vdpa/mlx5: Fix suboptimal range on iotlb iteration
[ Upstream commit 35025963326e44d8bced3eecd42d2f040f4f0024 ]

The starting iova address to iterate iotlb map entry within a range
was set to an irrelevant value when passing to the itree_next()
iterator, although luckily it doesn't affect the outcome of finding
out the granule of the smallest iotlb map size. Fix the code to make
it consistent with the following for-loop.

[ Upstream commit 7b22b7719fc17d5979a991c918c868ab041be5c8 ]

Any write access to the IMEM region when the Q6 is setting up XPU
protection on it will result in a XPU violation. Fix this by ensuring
IMEM writes related to the MBA post-mortem logs happen before the Q6
is brought out of reset.

74aba68dc8 rpmsg: glink: use only lower 16-bits of param2 for CMD_OPEN name length
[ Upstream commit 06c59d97f63c1b8af521fa5aef8a716fb988b285 ]

The name len field of the CMD_OPEN packet is only 16-bits and the upper
16-bits of "param2" are a different "prio" field, which can be nonzero in
certain situations, and CMD_OPEN packets can be unexpectedly dropped
because of this.

Fix this by masking out the upper 16 bits of param2.

[ Upstream commit 4e816d0318fdfe8932da80dbf04ba318b13e4b3a ]

The upstream GLINK driver was first introduced to communicate with the
RPM on MSM8996, presumably as an artifact from that era the command
defines was prefixed RPM_CMD, while they actually are GLINK_CMDs.

Let's rename these, to keep things tidy. No functional change.

0b27aa9523 PCI: cpqphp: Fix PCIBIOS_* return value confusion
[ Upstream commit e2226dbc4a4919d9c8bd9293299b532090bdf020 ]

Code in and related to PCI_RefinedAccessConfig() has three types of return
type confusion:

 - PCI_RefinedAccessConfig() tests pci_bus_read_config_dword() return value
   against -1.

 - PCI_RefinedAccessConfig() returns both -1 and PCIBIOS_* return codes.

 - Callers of PCI_RefinedAccessConfig() only test for -1.

Make PCI_RefinedAccessConfig() return PCIBIOS_* codes consistently and
adapt callers accordingly.

a531eca888 PCI: cpqphp: Use PCI_POSSIBLE_ERROR() to check config reads
[ Upstream commit a18a025c2fb5fbf2d1d0606ea0d7441ac90e9c39 ]

When config pci_ops.read() can detect failed PCI transactions, the data
returned to the CPU is PCI_ERROR_RESPONSE (~0 or 0xffffffff).

Obviously a successful PCI config read may *also* return that data if a
config register happens to contain ~0, so it doesn't definitively indicate
an error unless we know the register cannot contain ~0.

Use PCI_POSSIBLE_ERROR() to check the response we get when we read data
from hardware.  This unifies PCI error response checking and makes error
checks consistent and easier to find.

cc693f142d clk: clk-axi-clkgen: make sure to enable the AXI bus clock
[ Upstream commit c64ef7e4851d1a9abbb7f7833e4936973ac5ba79 ]

In order to access the registers of the HW, we need to make sure that
the AXI bus clock is enabled. Hence let's increase the number of clocks
by one.

In order to keep backward compatibility and make sure old DTs still work
we check if clock-names is available or not. If it is, then we can
disambiguate between really having the AXI clock or a parent clock and
so we can enable the bus clock. If not, we fallback to what was done
before and don't explicitly enable the AXI bus clock.

Note that if clock-names is given, the axi clock must be the last one in
the phandle array (also enforced in the DT bindings) so that we can reuse
as much code as possible.

The pmecc "user" structure is allocated in atmel_pmecc_create_user() and
was supposed to be freed with atmel_pmecc_destroy_user(), but this other
helper is never called. One solution would be to find the proper
location to call the destructor, but the trend today is to switch to
device managed allocations, which in this case fits pretty well.

Replace kzalloc() by devm_kzalloc() and drop the destructor entirely.

[ Upstream commit 0350d783ab888cb1cb48ced36cc28b372723f1a4 ]

While design wise the idea of converting the driver to use
the hierarchy of the IRQ chips is correct, the implementation
has (inherited) flaws. This was unveiled when platform_get_irq()
had started WARN() on IRQ 0 that is supposed to be a Linux
IRQ number (also known as vIRQ).

Rework the driver to respect IRQ domain when creating each MFD
device separately, as the domain is not the same for all of them.

There may be a potential integer overflow issue in
_dpu_core_perf_calc_clk(). crtc_clk is defined as u64, while
mode->vtotal, mode->hdisplay, and drm_mode_vrefresh(mode) are defined as
a smaller data type. The result of the calculation will be limited to
"int" in this case without correct casting. In screen with high
resolution and high refresh rate, integer overflow may happen.
So, we recommend adding an extra cast to prevent potential
integer overflow.

[ Upstream commit a84cdcea3b4feb46730c88454b5f85e828429c2b ]

This patch puts together all mailbox changes
for 98xx silicon:

Attach ->
Modify resource attach mailbox handler to
request LFs from a block address out of multiple
blocks of same type. If a PF/VF need LFs from two
blocks of same type then attach mbox should be
called twice.

Example:
        struct rsrc_attach *attach;
        .. Allocate memory for message ..
        attach->cptlfs = 3; /* 3 LFs from CPT0 */
        .. Send message ..
        .. Allocate memory for message ..
        attach->modify = 1;
        attach->cpt_blkaddr = BLKADDR_CPT1;
        attach->cptlfs = 2; /* 2 LFs from CPT1 */
        .. Send message ..

Detach ->
Update detach mailbox and its handler to detach
resources from CPT1 and NIX1 blocks.

MSIX ->
Updated the MSIX mailbox and its handler to return
MSIX offsets for the new block CPT1.

Free resources ->
Update free_rsrc mailbox and its handler to return
the free resources count of new blocks NIX1 and CPT1

Links ->
Number of CGX,LBK and SDP links may vary between
platforms. For example, in 98xx number of CGX and LBK
links are more than 96xx. Hence the info about number
of links present in hardware is useful for consumers to
request link configuration properly. This patch sends
this info in nix_lf_alloc_rsp.

9a8d1c9e3f drm: fsl-dcu: enable PIXCLK on LS1021A
[ Upstream commit ffcde9e44d3e18fde3d18bfff8d9318935413bfd ]

The PIXCLK needs to be enabled in SCFG before accessing certain DCU
registers, or the access will hang. For simplicity, the PIXCLK is enabled
unconditionally, resulting in increased power consumption.

3761594d08 drm/fsl-dcu: Convert to Linux IRQ interfaces
[ Upstream commit 03ac16e584e496230903ba20f2b4bbfd942a16b4 ]

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's
IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers
don't benefit from using it. DRM IRQ callbacks are now being called
directly or inlined.

fa21ee65e2 wifi: mwifiex: Fix memcpy() field-spanning write warning in mwifiex_config_scan()
[ Upstream commit d241a139c2e9f8a479f25c75ebd5391e6a448500 ]

Replace one-element array with a flexible-array member in `struct
mwifiex_ie_types_wildcard_ssid_params` to fix the following warning
on a MT8173 Chromebook (mt8173-elm-hana):

[  356.775250] ------------[ cut here ]------------
[  356.784543] memcpy: detected field-spanning write (size 6) of single field "wildcard_ssid_tlv->ssid" at drivers/net/wireless/marvell/mwifiex/scan.c:904 (size 1)
[  356.813403] WARNING: CPU: 3 PID: 742 at drivers/net/wireless/marvell/mwifiex/scan.c:904 mwifiex_scan_networks+0x4fc/0xf28 [mwifiex]

The "(size 6)" above is exactly the length of the SSID of the network
this device was connected to. The source of the warning looks like:

    ssid_len = user_scan_in->ssid_list[i].ssid_len;
    [...]
    memcpy(wildcard_ssid_tlv->ssid,
           user_scan_in->ssid_list[i].ssid, ssid_len);

There is a #define WILDCARD_SSID_TLV_MAX_SIZE that uses sizeof() on this
struct, but it already didn't account for the size of the one-element
array, so it doesn't need to be changed.

12fa2d67d1 drm/bridge: tc358767: Fix link properties discovery
[ Upstream commit 2d343723c7e1f9f6d64f721f07cfdfc2993758d1 ]

When a display controller driver uses DRM_BRIDGE_ATTACH_NO_CONNECTOR,
tc358767 will behave properly and skip the creation of the connector.

However, tc_get_display_props(), which is used to find out about the DP
monitor and link, is only called from two places: .atomic_enable() and
tc_connector_get_modes(). The latter is only used when tc358767 creates
its own connector, i.e. when DRM_BRIDGE_ATTACH_NO_CONNECTOR is _not_
set.

Thus, the driver never finds out the link properties before get_edid()
is called. With num_lanes of 0 and link_rate of 0 there are not many
valid modes...

Fix this by adding tc_get_display_props() call at the beginning of
get_edid(), so that we have up to date information before looking at the
modes.

9cd713378c netdevsim: copy addresses for both in and out paths
[ Upstream commit 2cf567f421dbfe7e53b7e5ddee9400da10efb75d ]

The current code only copies the address for the in path, leaving the out
path address set to 0. This patch corrects the issue by copying the addresses
for both the in and out paths. Before this patch:

  # cat /sys/kernel/debug/netdevsim/netdevsim0/ports/0/ipsec
  SA count=2 tx=20
  sa[0] tx ipaddr=0.0.0.0
  sa[0]    spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1
  sa[0]    key=0x3167608a ca4f1397 43565909 941fa627
  sa[1] rx ipaddr=192.168.0.1
  sa[1]    spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1
  sa[1]    key=0x3167608a ca4f1397 43565909 941fa627

After this patch:

  = cat /sys/kernel/debug/netdevsim/netdevsim0/ports/0/ipsec
  SA count=2 tx=20
  sa[0] tx ipaddr=192.168.0.2
  sa[0]    spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1
  sa[0]    key=0x3167608a ca4f1397 43565909 941fa627
