Rander Wang 130bce3afb ALSA: hdac: clear link output stream mapping
Fix potential DMA hang upon starting playback on devices in HDA mode
on Intel platforms (Gemini Lake/Whiskey Lake/Comet Lake/Ice Lake). It
doesn't affect platforms before Gemini Lake or any Intel device in
non-HDA mode.

The reset value for the LOSDIV register is all output streams valid.
Clear this register to invalidate non-existent streams when the bus
is powered up.

Takashi Iwai 19abfefd4c ALSA: hda: Direct MMIO accesses
HD-audio drivers access to the mmio registers indirectly via the
corresponding bus->io_ops callbacks.  This is because some platform
(notably Tegra SoC) requires the word-aligned access.  But it's rather
a rare case, and other platforms suffer from the penalties by indirect
calls unnecessarily.

This patch is an attempt to optimize and cleanup for this situation.
Now the special aligned access is used only when a new kconfig
CONFIG_SND_HDA_ALIGNED_MMIO is set.  And the HD-audio core itself
provides the aligned MMIO access helpers instead of the driver side.
If Kconfig isn't set (as default), the standard helpers like readl()
or writel() are used directly.

A couple of places in ASoC Intel drivers have the access via io_ops
reg_writel(), and they are replaced with the direct writel() calls.

And now with this patch, the whole bus->io_ops becomes empty, so it's
dropped completely.  The bus initialization functions are changed
accordingly as well to drop the whole bus->io_ops.

Takashi Iwai 619a1f195f ALSA: hda: Remove page allocation redirection
The HD-audio core allocates and releases pages via driver's specific
dma_alloc_pages and dma_free_pages ops defined in bus->io_ops.  This
was because some platforms require the uncached pages and the handling
of page flags had to be done locally in the driver code.

Since the recent change in ALSA core memory allocator, we can simply
pass SNDRV_DMA_TYPE_DEV_UC for the uncached pages, and the only
difference became about this type to be passed to the core allocator.
That is, it's good time for cleaning up the mess.

This patch changes the allocation code in HD-audio core to call the
core allocator directly so that we get rid of dma_alloc_pages and
dma_free_pages io_ops.  If a driver needs the uncached pages, it has
to set bus->dma_type right after the bus initialization.

This is merely a code refactoring and shouldn't bring any behavior
changes.

ALSA: hdac: Fix codec name after machine driver is unloaded and reloaded
Currently on each driver reload internal counter is being increased. It
causes failure to enumerate driver devices, as they have hardcoded:
.codec_name = "ehdaudio0D2",
As there is currently no devices with multiple hda codecs and there is
currently no established way to reliably differentiate, between them,
always assign bus->idx = 0;

This fixes a problem when we unload and reload machine driver idx gets
incremented, so .codec_name would've needed to be set to "ehdaudio1D2"
after first reload and so on.

ALSA: hdac: fix memory release for SST and SOF drivers
During the integration of HDaudio support, we changed the way in which
we get hdev in snd_hdac_ext_bus_device_init() to use one preallocated
with devm_kzalloc(), however it still left kfree(hdev) in
snd_hdac_ext_bus_device_exit(). It leads to oopses when trying to
rmmod and modprobe. Fix it, by just removing kfree call.

SOF also uses some of the snd_hdac_ functions for HDAudio support but
allocated the memory with kzalloc. A matching fix is provided
separately to align all users of the snd_hdac_ library.

snd_hdac_display_power() doesn't handle the concurrent calls carefully
enough, and it may lead to the doubly get_power or put_power calls,
when a runtime PM and an async work get called in racy way.

This patch addresses it by reusing the bus->lock mutex that has been
used for protecting the link state change in ext bus code, so that it
can protect against racy display state changes.  The initialization of
bus->lock was moved from snd_hdac_ext_bus_init() to
snd_hdac_bus_init() as well accordingly.

ASoC: Updates for v4.7

The updates this time around are almost all driver code:

 - Further slow progress on the topology code.
 - Substantial updates and improvements for the da7219, es8328, fsl-ssi
   Intel and rcar drivers.

Vinod Koul 4446085d21 ALSA: hdac: add link pm and ref counting
The HDA links can be switched off when not is use, similarly
command DMA can be stopped as well. This calls for a reference
counting mechanism on the link by it's users to manage the link
power. The DMA can be turned off when all links are off

For this we add two APIs
	snd_hdac_ext_bus_link_get
	snd_hdac_ext_bus_link_put

They help users to turn up/down link and manage the DMA as well

Jeeja KP a9c48f7f59 ALSA: hdac: Add support for hda DMA Resume capability
Skylake sports new capability of DMA resume, DRSM where we can
resume the DMA. This capability is defined by presence of
AZX_DRSM_CAP_ID.

If this capability is present, we use this capability.
So we add:

snd_hdac_ext_stream_drsm_enable() - DMA resume caps
snd_hdac_ext_stream_set_dpibr() - set the DMA position
snd_hdac_ext_stream_set_lpib() - set the lpib
