The DSP may send the same interrupt multiple times before it's handled
in the interrupt thread. Rather than masking it in the thread, mask it
in the handler directly.
This patch also removes useless checks that cannot happen, and masks
that are set don't need to be re-tested.

Hi Mark
Current ALSA SoC is handling dai_link related operation,
but it is implmemented directly without using function/macro,
and at random place.
This v4 patch-set creates new snd_soc_link_xxx() functions
which handles dai_link related operation,
and implmement these at new soc-link.c.
v3 -> v4
- add Reviewed-by from Ranjani and Pierre-Louis
- fix bisection error at [2/7]
v2 -> v3
- add missing #include <sound/soc-link.h> in soc-link.c
v1 -> v2
- #include <sound/soc-link.h> is added on each c source file
instead of soc.h
- not have extra error message after snd_soc_link_xxx(),
because it already indicate it via snc_link_ret()
- snd_soc_link_compr_xxx() doesn't have rtd parameter,
because it can be created from cstream

Hello,
extended firmware manifest is a method to retrieve capabilities
directly from the firmware file instead of routing the information via
the DSP and reading it back via IPC (latter mechanism still supported
but will be deprecated).
This feature was briefly merged to 5.8 with the series sent on
2020-Apr-15, but due to a regression hit with exporting uapi headers,
the patches got dropped.
Here's an update with the uapi header issue fixed, rebased to latest
'for-5.8' and a few minor fixes. This has been sitting in sof-dev for
some weeks and no further issues have been found. We also added
a check for the uapi-export case to SOF CI, so such errors would
not slip through again in the future.
Tooling support to create firmware files with an extended header
is available in SOF firmware repository (see the rimage tool) and
this part is already merged.

With dedicated power domain for asrc, power can be disabled after
probe and pm runtime suspend, then the value of all registers need to
be restored in pm runtime resume. So we can merge suspend/resume function
to runtime_suspend/resume function and enable regcache only in end of
probe.

This makes it possible to select CONFIG_SND_MMP_SOC_SSPA directly, as
opposed to via CONFIG_SND_MMP_SOC, and for the driver to bind to a device
tree node. That makes the driver useful on Device Tree based systems,
with audio-graph-card or simple-card.
The aforementioned card drivers control the master clock themselves and
don't call the set_dai_sysclk() or set_dai_pll(), thus the respective
handlers don't serve any purpose anymore. Instead, they return early and
the hw_params() handler sets the appropriate bitclk itself.
The register range is split into two -- for the RX block and for the TX
block. On a MMP2 there are two pairs of them; the first one has the
clock controller in the middle, while the second just has a hole:
0xd42a0c00 - 0xd42a0c30 RX1
0xd42a0c30 - 0xd42a0c40 Clocks
0xd42a0c80 - 0xd42a0cb0 TX1
0xd42a0d00 - 0xd42a0d30 RX2
0xd42a0d80 - 0xd42a0cb0 TX2
For this reason, mmp_sspa_write_reg() and mmp_sspa_read_reg() are
replaced with direct calls to I/O routines.
Tested on a MMP2-based OLPC XO-1.75 laptop with rt5631 coded, mmp_tdma DMA
engine and MMP2 clock controller glued together with audio-graph-card.
