On the hikey960 platform, only one domain is supported,
and you can see that the media business is all used by the domain created by the ion.
After adding IPU (AI) to Hikey970 platform, it uses its own domain,
so the underlying layer needs to support multiple page mapping of domain,
otherwise IPU and DRM mapping will conflict, resulting in IPU recognition of image failure.

Now that we call dma_map in the dma_buf API callbacks there is no need

Technically, calling dma_buf_map_attachment should return a buffer
properly dma_mapped. Add calls to dma_map_sg to begin_cpu_access to
ensure this happens. As a side effect, this lets Ion buffers take
advantage of the dma_buf sync ioctls.

Bugfix for the commit of a20c7f36bd3d ("PCI: Do not allocate more buses than available in
parent").With this patch enumeration stops digging deeper downstream as soon as bus num 0x01 has been assigned, which is always the case for a bridge device.This results in all devices behind a bridge bus to remain undetected, as these would be connected to bus 0x02 or higher.

This patch implement the AUX area interfaces required to
use the TMC (configured as an ETR) from the Perf sub-system.
The ETR is configured to work with contiguous memory only.
Although not optimal, it allows the IP block to be used
while the scatter-gather mode of operation is being worked
on.
The heuristic is heavily borrowed from the ETB10 and TMC-ETF
implementation.

The tmc_etr_enable_hw() fills the buffer with 0's before enabling
the hardware. So, we don't need an explicit memset() in
tmc_enable_etr_sink_sysfs() before calling the tmc_etr_enable_hw().
This patch removes the explicit memset from tmc_enable_etr_sink_sysfs.

The mode of operation of the TMC tracked in drvdata->mode is defined
as a local_t type. This is always checked and modified under the
drvdata->spinlock and hence we don't need local_t for it and the
unnecessary synchronisation instructions that comes with it. This
change makes the code a bit more cleaner.
Also fixes the order in which we update the drvdata->mode to
CS_MODE_DISABLED. i.e, in tmc_disable_etX_sink we change the
mode to CS_MODE_DISABLED before invoking tmc_disable_etX_hw()
which in turn depends on the mode to decide whether to dump the
trace to a buffer.

When using coresight from the perf interface sinks are specified
as part of the perf command line. As such the sink needs to be
disabled once it has been acknowledged by the coresight framework.
Otherwise the sink stays enabled, which may interfere with other
sessions.
This patch removes the sink selection check from the build path
process and make it a function on it's own. The function is
then used when operating from sysFS or perf to determine what
sink has been selected.

As the next patches will provide support for the hikey3660's sensor,
several functions with the same purpose but for different platforms will
be introduced.
In order to make a clear distinction between them, let's prefix the
function names with the platform name.
This patch has no functional changes, only name changes.
