Set SNDRV_PCM_HW_PARAM_BUFFER_BYTES contraint that matches with
SNDRV_PCM_HW_PARAM_PERIOD_BYTES constraint.For some reason setting the hw params with snd_pcm_hw_params_*_near()
functions sometimes fails if the period bytes constraint is set
without a matching buffer bytes constraint.Signed-off-by: Jyri Sarha

The HDMI sound uses a simple card created programatically, so
the preferred card id cannot be passed through an alias via DT.
The card id hint is taken from the HDMI HW IP's alias instead,
which does have a DT entry.Signed-off-by: Misael Lopez Cruz
-
The card id hint for the DT case is covered by ASoC core, so
id hint for the non-DT case has to be explicitly handled by
the simple card driver.Signed-off-by: Misael Lopez Cruz

Via slots_reserved module param array one can specify which card slots
should not be considered when assigning card slots automatically.
These reserved slots can only be taken if a card driver specifically
requests the slot via snd_card_create().Signed-off-by: Peter Ujfalusi

An underrun (playback) event occurs when the serializer transfer
data from the XRBUF buffer to the XRSR shift register, but the
XRBUF hasn't been filled. Similarly, the overrun (capture) event
occurs when data from the XRSR shift register is transferred to
the XRBUF but it hasn't been read yet.These events are handled as XRUN events that cause the pcm to stop.
The stream has to be explicitly restarted by the userspace which
ensures that after stopping/starting McASP the data transfer is
aligned with DMA. The other possibility was to internally stop and
start McASP without DMA even knowing about it.Signed-off-by: Misael Lopez Cruz

Active slots count depends on the number of channels in the stream
and the number of active serializers. Each serializer will handle
at most the number of channels specified via 'tdm-slots' parameter
in DT.There are two possible scenarios:
- Single serializer: channel count fits in the max slots supported by
McASP serializers, active slots is same as channel count- Multiple serializers: channel count is bigger than max slots supported
by a serializer. Channel count determines how many serializers are
needed at their max slot count configurationSigned-off-by: Misael Lopez Cruz
Signed-off-by: Peter Ujfalusi -
In IIS (I2S, TDM, etc) mode the maximum number of allowed channels for
either direction can be:
number of serializers for the direction * tdm_slots.
This constraint applicable for the first stream, while consequent stream
should not have more channels then the first stream.Signed-off-by: Peter Ujfalusi
-
Instead of validating the tdm_slots parameter every time at hw_params we
can do it once during probe. If the parameter is not valid (32)
print an error and fix it up.Signed-off-by: Peter Ujfalusi
-
TDM support is achieved using DSP transfer mode and setting a
programmable offset which specifies where data begins with
respect to the frame sync.It requires 256-clock mode if CODEC is master (not currently
supported in the driver). No additional dependency if CODEC
is slave.Signed-off-by: Misael Lopez Cruz

Now that we have a generic card driver we can't rely on the card driver
selecting the CODECs for us so make the CODECs that can be enabled with
OF directly selectable in Kconfig. For the platforms not using OF it's
not clear that we don't still want to have some board specific selection
since the kernel needs to contain code to register the devices; ACPI could
provide this from firmware does not yet support any kind of generic card.It may also be desirable to hide these if OF is not enabled to reduce
noise.Signed-off-by: Mark Brown

commit f3ee07d8b6e061bf34a7167c3f564e8da4360a99 upstream.
ALC269 & co have many vendor-specific setups with COEF verbs.
However, some verbs seem specific to some codec versions and they
result in the codec stalling. Typically, such a case can be avoided
by checking the return value from reading a COEF. If the return value
is -1, it implies that the COEF is invalid, thus it shouldn't be
written.This patch adds the invalid COEF checks in appropriate places
accessing ALC269 and its variants. The patch actually fixes the
resume problem on Acer AO725 laptop.Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=52181

commit f475371aa65de84fa483a998ab7594531026b9d9 upstream.
On some HP laptops, the mute led is controlled by codec gpio.
When some machine resume from s3/s4, the codec gpio data will be
cleared to 0 by BIOS:
Before suspend:
IO[3]: enable=1, dir=1, wake=0, sticky=0, data=1, unsol=0
After resume:
IO[3]: enable=1, dir=1, wake=0, sticky=0, data=0, unsol=0To skip the AFG node to enter D3 can't fix this problem.
A workaround is to restore the gpio data when the system resume
back from s3/s4. It is safe even on the machines without this
problem.BugLink: https://bugs.launchpad.net/bugs/1358116
