This API allows clients to manually inform the DMAC when they need more
data copied. The DMAC can then copy the desired amount of data.

Due to misplaced parentheses the computation gives half of correct
result and omits rounding. Currently this macro is not used by code
in SOF git repository. Developers who may use format.h macros should
check their code.

On Apollolake, the interrupt number for different channels of
the same controller are different, here add implementation of
it: register interrupt handler for each channel, and don't
need check channel in its specific handler anymore.

Use Linux checkpatch.pl to check for style problems on each commit
rather than waste time on mailing lists.
The hooks are installed by default with autogen.sh if there are
no pre-existing hooks, e.g. if a global template is used.
Commits can still be forced by using git commit -n (or --no-verify) if
you absolutely need to bypass checkpatch.pl in a work branch.
Note that both checkpatch.pl and spelling.txt are provided under
a GPL v2 license.

Allow interrupts to have a parent and child relationship in order to
support nested interrupts between different HW interrupt controllers.
This patch allows child handler to be registered for secondary interrupt
controllers and allow multiple child interrupt sources to share a single
interrupt pin.

Coverity issue: 254842 Uninitialized scalar variable
The variable will contain an arbitrary value left from earlier
computations.
In parse_page_descriptors: Use of an uninitialized variable (CWE-457)
The elem.src variable is not initialized, but in
dma_trace_host_buffer() the code reads this initialized value.
Break
*e = *elem;
in
e->dest = elem->dest;
e->size = elem->size;
to only access relevant fields.
