A few fixes addressing:

- Link-time error with __exit annotation for virtio_scmi_exit
- Unnecessary nested irqsave/irqrestore spinlocks in virtio transport
- Missing SMP barriers to protect accesses to SCMI virtio device

Fixes for omaps for v5.15

Few regression fixes for omaps for the v5.15-rc cycle. There is a fix
for boot time hangs that can happen on some am335x devices that started
when the pruss devicetree nodes were added. The other fixes are less
critical:

- Fix compiler warning for sysc_init_soc() that got recently introduced

- Fix external abort for am335x pruss as otherwise some am335x will hang

- Use CLKDM_NOAUTO quirk also for dra7 dcan1

- Fix older NAND device node regression for omap3-sdp

Only one single SCMI Virtio device is currently supported by this driver
and it is referenced using a static global variable which is initialized
once for all during probing and nullified at virtio device removal.

Add proper SMP barriers to protect accesses to such device reference to
ensure that the initialzation state of such device is correctly observed by
all PEs at any time.

Return -EBUSY, instead of -EINVAL, and a descriptive error message if more
than one SCMI Virtio device is ever found and probed.

Merge in a fix for pruss reset issue caused by enabling pruss for am335x.

gcc warns that accessing a pointer based on a numeric constant may
be an offset into a NULL pointer, and would therefore has zero
accessible bytes:

arch/arm/common/sharpsl_param.c: In function ‘sharpsl_save_param’:
arch/arm/common/sharpsl_param.c:43:9: error: ‘memcpy’ reading 64 bytes from a region of size 0 [-Werror=stringop-overread]

      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In this particular case, the warning is bogus since this is the actual
pointer, not an offset on a NULL pointer. Add a local variable to shut
up the warning and hope it doesn't come back.

Qualcomm driver fixes for v5.15

This restricts the QCOM_SCM driver to depend on ARCH_QCOM, to reduce
it's presence after becoming a loadable module.

It then fixes a regression in the mdt_loader, where firmware with the
hash segment marked as PT_LOAD would no longer be accepted, preventing
several MSM8974 and SDM660 devices from loading remoteproc firmware.

Lastly it corrects the drvdata associated with the socinfo device during

It then moves the reserved-memory changes done to get IPA working on the

With commit c709135e ("pinctrl: at91-pio4: add support for slew-rate")
and commit cbde6c82 ("pinctrl: at91-pio4: Fix slew rate disablement")
the slew-rate is enabled by default for each configured pin. The datasheet
specifies at chapter "Output Driver AC Characteristics" that HSIO
drivers (use in SDMMCx and QSPI0 peripherals), don't have a slewrate
setting but are rather calibrated against an external 1% resistor mounted
on the SDMMCx_CAL or QSPI0_CAL pins. Depending on the target signal
frequency and the external load, it is possible to adjust their target
output impedance. Thus set slew-rate = <0> for SDMMC (QSPI is not enabled
at the moment in device tree).

In suspend/resume procedure for AT91 architecture different controllers
(PMC, SHDWC, RAM, RAM PHY, SFRBU) are accessed to do the proper settings
for power saving. Commit f0bbf179 ("ARM: at91: pm: add self-refresh
support for sama7g5") introduced the access to RAMC PHY controller for
SAMA7G5. The access to this controller is done after RAMC ports are
closed, thus any TLB walk necessary for RAMC PHY virtual address will
fail. In the development branch this was not encountered. However, on
current kernel the issue is reproducible.

To solve the issue the previous mechanism of pre-loading the TLB with
the RAMC PHY virtual address has been used. However, only the addition
of this new pre-load breaks the functionality for ARMv5 based
devices (SAM9X60). This behavior has been encountered previously
while debugging this code and using the same mechanism for pre-loading
address for different controllers (e.g. pin controller, the assumption
being that other requested translations are replaced from TLB).

To solve this new issue the TLB flush + the extension of pre-loading
the rest of controllers to TLB (e.g. PMC, RAMC) has been added. The
rest of the controllers should have been pre-loaded previously, anyway.

SAMA7G5-EK board has DDR3L type of memory soldered. This needs 1.35V. The
1.35V for DDR3L rail at run-time is selected by the proper configuration
on SELV2 pin (for 1.35V it needs to be in high-z state). When suspended
the MCP16502 PMIC soldered on SAMA7G5-EK will use different sets of
configuration registers to provide proper voltages on its rail. Run-time
configuration registers could be configured differently than suspend
configuration register for MCP16502 (VSEL2 affects only run-time
configuration). In suspend states the DDR3L memory soldered on SAMA7G5-EK
switches to self-refresh. Even on self-refresh it needs to be powered by
a 1.35V rail. Thus, make sure the PMIC is configured properly when system
is suspended.

Before commit 0e30f472

 ("mtd: spi-nor: add support for DTR protocol"),
for all PP command, it only support 1-1-1 mode, no matter the tx setting
in dts. But after the upper commit, the logic change. It will choose
the best mode(fastest mode) which flash device and spi-nor host controller
both support.

qspi and fspi host controller do not support read 1-4-4 mode. so need to
set the tx to 1, let the common code finally select read 1-1-4 mode.

Though the spi-nor device on imx6sx-sdb/imx6ul(l/z)-14x14-evk board
do not support PP-1-4-4/PP-1-1-4, but if tx is 4 in dts file, it will also
impact the read mode selection. For the spi-nor device on the upper mentioned
boards, they support read 1-4-4 mode and read 1-1-4 mode according to the
device internal sfdp register. But qspi host controller do not support
read 1-4-4 mode. so need to set the tx to 1, let the common code finally
select read 1-1-4 mode, PP-1-1-1 mode.

Starting with v5.15-rc1, we may now see some am335x beaglebone black
device produce the following error on pruss probe:

Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0326000

This has started with the enabling of pruss for am335x in the dts files.

Turns out the is caused by the PRM reset handling not waiting for the
reset bit to clear. To fix the issue, let's always wait for the reset
bit to clear, even if there is a separate reset status register.

We attempted to fix a similar issue for dra7 iva with a udelay() in
commit effe89e4 ("soc: ti: omap-prm: Fix occasional abort on reset
deassert for dra7 iva"). There is no longer a need for the udelay()
for dra7 iva reset either with the check added for reset bit clearing.

Commit 078fb7aa ("arm: dts: vexpress: Fix addressing issues with
'motherboard-bus' nodes") broke booting on a couple of 32-bit VExpress
boards. The problem is #address-cells size changed, but interrupt-map
was not updated. This results in the timer interrupt (and all the
other motherboard interrupts) not getting mapped.

As the 'interrupt-map' properties are all just duplicates across boards,
just move them into vexpress-v2m.dtsi and vexpress-v2m-rs1.dtsi.
Strictly speaking, 'interrupt-map' is dependent on the parent
interrupt controller, but it's not likely we'll ever have a different
parent than GICv2 on these old platforms. If there was one,
'interrupt-map' can still be overridden.
