Arm FF-A fixes for v6.7

A bunch of fixes addressing issues around the notification support that
was added this cycle. They address issue in partition IDs handling in
ffa_notification_info_get(), notifications cleanup path and the size of
the allocation in ffa_partitions_cleanup().

It also adds check for the notification enabled state so that the drivers
registering the callbacks can be rejected if not enabled/supported.

It also moves the partitions setup operation after the notification
initialisation so that the driver has the correct state for notification
enabled/supported before the partitions are initialised/setup.

It also now allows FF-A initialisation to complete successfully even
when the notification initialisation fails as it is an optional support
in the specification. Initial support just allowed it only if the
firmware didn't support notifications.

Finally, it also adds a fix for smatch warning by declaring ffa_bus_type
structure in the header.

RISC-V Devicetree fixes for v6.7-rc4

Two fixes, both rather minor. The first fixes some dtbs_check warnings
introduced after an update to the bindings, that returns the
architecture to being clean of dtbs_check issues. The second relocates
a soc-specific property to the appropriate location in $soc.dtsi, and
hopefully avoids the same mistake being copy-pasted into more

still some board device trees may not contain the substring and would

The i.MX8MP and i.MX8MQ devices both use the same DWC3 controller and
are both affected by a known issue with the controller due to specific
behaviour when park mode is enabled in SuperSpeed host mode operation.

Under heavy USB traffic from multiple endpoints the controller will
sometimes incorrectly process transactions such that some transactions
are lost, or the controller may hang when processing transactions. When
the controller hangs it does not recover.

This issue is documented partially within the linux-imx vendor kernel
which references a Synopsys STAR number 9001415732 in commits [1] and
additional details in [2]. Those commits provide some additional
controller internal implementation specifics around the incorrect
behaviour of the SuperSpeed host controller operation when park mode is
enabled.

The summary of this issue is that the host controller can incorrectly
enter/exit park mode such that part of the controller is in a state
which behaves as if in park mode even though it is not. In this state
the controller incorrectly calculates the number of TRBs available which
results in incorrect access of the internal caches causing the overwrite
of pending requests in the cache which should have been processed but
are ignored. This can cause the controller to drop the requests or hang
waiting for the pending state of the dropped requests.

The workaround for this issue is to disable park mode for SuperSpeed
operation of the controller through the GUCTL1[17] bit. This is already
available as a quirk for the DWC3 controller and can be enabled via the
'snps,parkmode-disable-ss-quirk' device tree property.

It is possible to replicate this failure on an i.MX8MP EVK with a USB
Hub connecting 4 SuperSpeed USB flash drives. Performing continuous
small read operations (dd if=/dev/sd... of=/dev/null bs=16) on the block
devices will result in device errors initially and will eventually
result in the controller hanging.

The multiplier is already promoted to unsigned long, however the
frequency calculations done when using level indexing mode doesn't
use the multiplier computed. It instead hardcodes the multiplier
value of 1000 at all the usage sites.

Clean that up by assigning the multiplier value of 1000 when using
the perf level indexing mode and update the frequency calculations to
use the multiplier instead. It should fix the possible frequency
truncation for all the values greater than or equal to 4GHz on 64-bit

Clocks for each power domain are split into big categories: pd clocks
and subsys clocks.
According to the binding, all clocks which have a dash '-' in their name
are treated as subsys clocks, and must be placed at the end of the list.
The other clocks which are pd clocks must come first.
Fixed the naming and the placing of all clocks in the power domains.
For the avoidance of doubt, prefixed all subsys clocks with the 'subsys'
prefix. The binding does not enforce strict clock names, the driver
uses them in bulk, only making a difference for pd clocks vs subsys clocks.

The above problem appears to be trivial, however, it leads to incorrect
power up and power down sequence of the power domains, because some
clocks will be mistakenly taken for subsys clocks and viceversa.
One consequence is the fact that if the DIS power domain goes power down
and power back up during the boot process, when it comes back up, there
are still transactions left on the bus which makes the display inoperable.

Some of the clocks for the DIS power domain were wrongly using '_' instead
of '-', which again made these clocks being treated as pd clocks instead of
subsys clocks.

Eric reports errors on emmc with hs400 mode when booting linux on bpi-r3
without uboot [1]. Booting with uboot does not show this because clocks
seem to be initialized by uboot.

Fix this by adding assigned-clocks and assigned-clock-parents like it's
done in uboot [2].

Before suspending the LARBs we're making sure that any operation is
done: this never happens because we are unexpectedly unclocking the
LARB20 before executing the suspend handler for the MediaTek Smart
Multimedia Interface (SMI) and the cause of this is incorrect clocks
on this LARB.

Fix this issue by changing the Local Arbiter 20 (used by the video
encoder secondary core) apb clock to CLK_VENC_CORE1_VENC;
furthermore, in order to make sure that both the PM resume and video
encoder operation is stable, add the CLK_VENC(_CORE1)_LARB clock to
the VENC (main core) and VENC_CORE1 power domains, as this IP cannot
communicate with the rest of the system (the AP) without local
arbiter clocks being operational.

The LED ACT which is included from bcm2711-rpi-4-b doesn't exists
on the Raspberry Pi 400. So the bcm2711-rpi-400.dts tries to
use the delete-node directive in order to remove the complete
node. Unfortunately the usage get broken in commit 1156e3a7
("ARM: dts: bcm283x: Move ACT LED into separate dtsi")
and now ACT and PWR LED using the same GPIO and this prevent
probing of led-gpios on Raspberry Pi 400:

    leds-gpio: probe of leds failed with error -16

So fix the delete-node directive.
