Add i.MX93 mediamix blk ctrl support.
i.MX93 mediamix blk ctrl has registers to set QoS(priority) value.
It support default QoS value and cfg QoS value. Set an initial
value from i.MX design team. If LCDIF/ISI/PXP wanna a different QoS
value in future, they could use interconnect to request bandwidth.

This updates the bindings in order to use names for the boards that
follow the latest convention used by Kontron marketing.
By updating we make sure, that we can maintain this more easily in

This updates the bindings in order to simplify the devicetree
structure and to add names for the boards that follow the latest
convention used by Kontron marketing.
It also gets rid of the N6xxx notation in the compatibles and
file names, as they are not really used anymore and often result
in confusion.
This is a breaking change, but the impact shouldn't be too big
and it makes usage and maintenance easier in the future.

Arm FF-A firmware driver updates for v6.1
Small set of changes in preparation to add support for FF-A v1.1
specification later. It mainly contains:
1. Splitting up ffa_ops into different categories namely information,
message and memory. It helps to make info and memory operations
independent from ffa_device so thata generic memory management
module can use it without specific ffa_dev.
2. Adds support for querying FF-A features and use the same to detect
the support for 64-bit operations.
3. Adds v1.1 get_partition_info support and use the same to set up
32-bit execution mode flag automatically.
4. Adds pointer to the ffa_dev_ops in struct ffa_dev and drop
ffa_dev_ops_get() which enables to drop ffa_ops in optee_ffa
structure using ffa_dev->ops directly. Additionally ffa_dev_ops is
renamed as ffa_ops.

While at it, use dev_err_probe() to further simplify the code. This is also

The DMA subsystem could be entirely disabled in Kconfig and then the
TEGRA20_APB_DMA option isn't available too. Hence kernel configuration
fails if DMADEVICES Kconfig option is disabled due to the unsatisfiable
dependency.
The FUSE driver isn't a critical driver and currently it only provides
NVMEM interface to userspace which isn't known to be widely used, and
thus, it's fine if FUSE driver fails to load.
Let's remove the erroneous Kconfig dependency and let the FUSE driver to
fail the probing if DMA is unavailable.

Simple wake events are neither mapped to GIC interrupts nor have an
associated GPIO line. They are close to GPIO-backed wake events in that
the IRQ hierarchy processing needs to stop at the PMC level, but since
there is no dedicated GPIO line for them, let's turn them into a
separate type.
