bbfbb57958 Qualcomm driver fixes for v6.12
The Qualcomm EDAC driver's configuration of interrupts is made optional,
 to avoid violating security constriants on X Elite platform .
 
 The SCM drivers' detection mechanism for the presence of SHM bridge in QTEE,
 is corrected to handle the case where firmware successfully returns that
 the interface isn't supported.
 
 The GLINK driver and the PMIC GLINK interface is updated to handle
 buffer allocation issues during initialization of the communication
 channel.
 
 Allocation error handling in the socinfo dirver is corrected, and then
 the fix is corrected.

566064e570 More Qualcomm Arm64 DeviceTree fixes for v6.12
Bring a range of PCIe fixes across the X Elite platform, as well as
 marking the NVMe power supply boot-on to avoid glitching the power
 supply during boot.
 
 The X Elite CRD audio configuration sees a spelling mistake corrected.
 
 On SM8450 the PCIe 1 PIPE clock definition is corrected, to fix a
 regression where this isn't able to acquire it's clocks.

c3b56da655 Arm SCMI fixes for v6.12(part 2)
Couple of fixes to address slab-use-after-free in scmi_bus_notifier()
 via scmi_dev->name and possible incorrect clear channel transport
 operation on A2P channel if some sort of P2A only messages are initiated
 on A2P channel(occurs when stress tested passing /dev/random to the
 channel).
 
 Apart from this, there are fixes to address missing "arm" prefix in the
 recently added property max-rx-timeout-ms which was missed in the review
 but was identified when further additions to the same binding were
 getting reviewed.

 and one disabling unused nodes that caused warnings at probe time.
 
 Firmware:
 Fix the poll_complete() implementation in the auto-update driver so that

 Misc:
 Update the maintainer pattern for my dts entry, so that it covers
 the specific platforms listed , rather than including all riscv
 platforms with the list platforms excluded.

08846522d9 arm64: dts: rockchip: Correct GPIO polarity on brcm BT nodes
Paragraph "3.4 Power up Timing Sequence" of the AzureWave-CM256SM
datasheet mentions the following about the BT_REG_ON pin, which is
connected to GPIO0_C4_d:

  When this pin is low and WL_REG_ON is high,
  the BT section is in reset.

Therefor set that pin to GPIO_ACTIVE_HIGH so that it can be pulled low
for a reset.
If set to GPIO_ACTIVE_LOW, the following errors are observed:

  Bluetooth: hci0: command 0x0c03 tx timeout
  Bluetooth: hci0: BCM: Reset failed (-110)

So fix the GPIO polarity by setting it to ACTIVE_HIGH.
This also matches what other devices with the same BT device have.

f8c8791924 soc: qcom: pmic_glink: Handle GLINK intent allocation rejections
Some versions of the pmic_glink firmware does not allow dynamic GLINK
intent allocations, attempting to send a message before the firmware has
allocated its receive buffers and announced these intent allocations
will fail. When this happens something like this showns up in the log:

    pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to send altmode request: 0x10 (-125)
    pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to request altmode notifications: -125
    ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI read request: -125
    qcom_battmgr.pmic_glink_power_supply pmic_glink.power-supply.0: failed to request power notifications

GLINK has been updated to distinguish between the cases where the remote
is going down (-ECANCELED) and the intent allocation being rejected
(-EAGAIN).

Retry the send until intent buffers becomes available, or an actual
error occur.

To avoid infinitely waiting for the firmware in the event that this
misbehaves and no intents arrive, an arbitrary 5 second timeout is
used.

This patch was developed with input from Chris Lew.

a387e73fed rpmsg: glink: Handle rejected intent request better
GLINK operates using pre-allocated buffers, aka intents, where incoming
messages are aggregated before being passed up the stack. In the case
that no suitable intents have been announced by the receiver, the sender
can request an intent to be allocated.

The initial implementation of the response to such request dealt
with two outcomes; granted allocations, and all other cases being
considered -ECANCELLED (likely from "cancelling the operation as the
remote is going down").

But on some channels intent allocation is not supported, instead the
remote will pre-allocate and announce a fixed number of intents for the
sender to use. If for such channels an rpmsg_send() is being invoked
before any channels have been announced, an intent request will be
issued and as this comes back rejected the call fails with -ECANCELED.

Given that this is reported in the same way as the remote being shut
down, there's no way for the client to differentiate the two cases.

In line with the original GLINK design, change the return value to
-EAGAIN for the case where the remote rejects an intent allocation
request.

It's tempting to handle this case in the GLINK core, as we expect
intents to show up in this case. But there's no way to distinguish
between this case and a rejection for a too big allocation, nor is it
possible to predict if a currently used (and seemingly suitable) intent
will be returned for reuse or not. As such, returning the error to the
client and allow it to react seems to be the only sensible solution.

In addition to this, commit 'c05dfce0b8 ("rpmsg: glink: Wait for
intent, not just request ack")' changed the logic such that the code
always wait for an intent request response and an intent. This works out
in most cases, but in the event that an intent request is rejected and no
further intent arrives (e.g. client asks for a too big intent), the code
will stall for 10 seconds and then return -ETIMEDOUT; instead of a more
suitable error.

This change also resulted in intent requests racing with the shutdown of
the remote would be exposed to this same problem, unless some intent
happens to arrive. A patch for this was developed and posted by Sarannya
S [1], and has been incorporated here.

To summarize, the intent request can end in 4 ways:
- Timeout, no response arrived => return -ETIMEDOUT
- Abort TX, the edge is going away => return -ECANCELLED
- Intent request was rejected => return -EAGAIN
- Intent request was accepted, and an intent arrived => return 0

This patch was developed with input from Sarannya S, Deepak Kumar Singh,
and Chris Lew.

4fbb73416b arm64: dts: imx8mp-phyboard-pollux: Set Video PLL1 frequency to 506.8 MHz
The LVDS panel on this device uses 72.4 MHz pixel clock, set IMX8MP_VIDEO_PLL1
to 72.4 * 7 = 506.8 MHz so the LDB serializer and LCDIFv3 scanout engine can
reach accurate pixel clock of exactly 72.4 MHz.

Without this patch, the Video PLL1 frequency is the default set in imx8mp.dtsi
which is 1039.5 MHz, which divides down to inaccurate pixel clock of 74.25 MHz
which works for this particular panel by sheer chance.

Stop taking that chance and set correct accurate pixel clock frequency instead.

 - btusb: Fix not being able to reconnect after suspend

 - btusb: Fix regression with fake CSR controllers 0a12:0001

Note: normally the bluetooth fixes go through the networking tree, but
this missed the weekly merge, and two of the commits fix regressions
that have caused a fair amount of noise and have now hit stable too:

  https://lore.kernel.org/all/4e1977ca-6166-4891-965e-34a6f319035f@leemhuis.info/

So I'm pulling it directly just to expedite things and not miss yet
