the codec couldn't provide itself as clock master. The codec

provided so this restriction isn't necessary for slave mode. The
code was also flawed with regards to setting of the frame offset

effect of impacting the min and max channels for the codec, in
soc_pcm_hw_params() through the call to

is clock master, and dynamically determines the BCLK offset

tlv320aic32x4: delay i2c access by 1 ms after hardware reset

As stated in 'TLV320AIC3254 Application Reference Guide' ([1]):

  3.2 Device Startup Lockout Times
    After the TLV320AIC3254 initializes through hardware reset at power-up
    or software reset, the internal registers initialize to default values.
    This initialization takes place within 1ms after pulling the RESET
    signal high. During this initialization phase, no register-read or
    register-write operation should be performed on ADC or DAC coefficient
    buffers. Also, no block within the codec should be powered up during
    the initialization phase.

5 years agoASoC: core: don't increase component module refcount unconditionally
Pierre-Louis Bossart [Fri, 1 Feb 2019 17:22:23 +0000 (11:22 -0600)]
ASoC: core: don't increase component module refcount unconditionally

The ASoC core has for the longest time increased the module reference
counts, even before the transition to the component model. This is
probably fine on most platforms, but it introduces a deadlock case on
Intel devices with the Skylake and SOF drivers which cannot be removed
due to their reference counts being modified by the core.

In these 2 cases, the PCI or ACPI driver .probe creates a platform
device to let the machine driver .probe register the audio
card. Conversely the PCI or ACPI driver .remove will unregister the
platform device which results in the card being removed by the machine
driver .remove.

With ascii art, this can be represented as

modprobe
snd_soc_skl/
soc-pci-dev/sof-acpci-dev  ----------> pci/acpi probe
       ^                                    |
       |                     ---------------|
       |                    |               |
       |                    V               V
    increase            register        register machine
    refcount            component       platform_device
       ^                                    |
       |                                    |
       |                                    V
    component <----   register card  <---- probe
    probe

The issue is that by playing with the component's module reference
counts during the card registration, it's no longer possible to remove
the module which controls the component. This can be shown, e.g. with
the following error:

root@plb-XPS-13-9350:~# lsmod | grep snd_soc_skl
snd_soc_skl           110592  1

root@plb-XPS-13-9350:~# rmmod snd_soc_skl
rmmod: ERROR: Module snd_soc_skl is in use

Increasing the reference count during the component probe is not
useful. If the PCI/ACPI module is removed, the card will be removed
anyway.

To avoid breaking existing platforms and allowing Intel platforms to
safely deal with module load/unload cases, this patch introduces a
flag which needs to be set during the component initialization. This
is a strictly opt-in capability that should only be used when the
handling of the component module does not require a reference count
increase to prevent removal during use.

Note that this solution is not directly applicable to the legacy
Atom/SST driver, which uses a different device hierarchy. There are
however additional refcount issues which prevent the ACPI driver from
being removed. This is a different issue which would need a different
patch.
