      ASoC: core: Fix component_list corruption when unloading modules · 4da53393
      由 Jarkko Nikula 提交于 
      This fixes module unload regressions introduced by commits 98e639fb
("ASoC: Track which components have been registered with
snd_soc_register_component()") and b37f1d12 ("ASoC: Let snd_soc_platform
subclass snd_soc_component").

First commit causes component_list to be corrupted when removing codec and
second when removing platform. Reason for both is that components associated
with platform or codec are never removed from the list because for them
registered_as_component field in struct snd_soc_component is always false.

Now list becomes corrupted when snd_soc_unregister_platform() or
snd_soc_unregister_codec() frees the platform or codec structure and where
the associated struct snd_soc_component is embedded.

Fix these by moving component unregistration and cleanup to a new local
function __snd_soc_unregister_component() that takes component as its
argument.

Since component is known for platforms and codecs the
__snd_soc_unregister_component() can be called directly and
snd_soc_unregister_component() takes care to find and unregister only
components that were registered using snd_soc_register_component().

      ASoC: core: Don't break component searching if both id and num_dai are 0 · 3dcba280
      由 Nicolin Chen 提交于 
      The commit e41975ed (ASoC: core: Fix the DAI name getting) added a break
within the "if (id < 0 || id >= pos->num_dai)" while the original design
of the search didn't break the loop if that condition contented but only
mark the ret error and let it go on to search the next component.

In a case like dmaengine which's not a dai but as a component sharing an
identical name with a dai, both the id and pos->num_dai here could be 0.
If we break the search, we may never find the dai we want as it might be
placed behind its dmaengine in the component list.

So this patch fixes the issue above by following the original design to
let the search carry on.

      ASoC: Move standard kcontrol helpers to the component level · 907fe36a
      由 Lars-Peter Clausen 提交于 
      After moving the IO layer inside ASoC to the component level we can now easily
move the standard control helpers also to the component level. This allows to
reuse the same standard helper control implementations for other components.

      ASoC: Move IO abstraction to the component level · e2c330b9
      由 Lars-Peter Clausen 提交于 
      We currently have two very similar IO abstractions in ASoC, one for CODECs, the
other for platforms. Moving this to the component level will allow us to unify
those two. It will also enable us to move the standard kcontrol helpers as well
as DAPM support to the component level.

The new component level abstraction layer is primarily build around regmap.
There is a per component pointer for the regmap instance for the underlying
device. There are four new function snd_soc_component_read(),
snd_soc_component_write(), snd_soc_component_update_bits() and
snd_soc_component_update_bits_async(). They have the same signature as their
regmap counter-part and will internally forward the call one-to-one to regmap.
If the component it not using regmap it will fallback to using the custom IO
callbacks. This is done to be able to support drivers that haven't been
converted to regmap yet, but it is expected that this will eventually be removed
in the future once all component drivers have been converted to regmap.

      ASoC: Add a per component dai list · 1438c2f6
      由 Lars-Peter Clausen 提交于 
      Now that every DAI has a component we can track the DAIs on a per component
basis. This simplifies the DAI lookup when we are only interested in DAIs of a
specific component and also makes it possible to have multiple components with
the same parent device and also register DAIs.

      ASoC: Pass CODEC to snd_soc_register_dais() · 6cc240f3
      由 Lars-Peter Clausen 提交于 
      snd_soc_register_dais() looks up the CODEC that is registering the DAIs by
looping over all registered CODECs. This patch updates the code to
simply pass the CODEC that registers the DAIs to snd_soc_register_dais() thus
avoiding the lookup.

      ASoC: Consolidate snd_soc_register_dai() and snd_soc_register_dais() · 32c9ba54
      由 Lars-Peter Clausen 提交于 
      snd_soc_register_dais() has basically the same code as snd_soc_register_dai(),
but running in a loop. The only difference is that snd_soc_register_dai() calls
fmt_single_name() to generate the DAIs name and snd_soc_register_dais() calls
fmt_multiple_name(). This patch pushes the check in __snd_soc_register_component()
which decides whether to call snd_soc_register_dai() or snd_soc_register_dais()
to snd_soc_register_dais() to decide which naming scheme to use. This allows us
to remove snd_soc_register_dai().

The patch also updates snd_soc_register_dais() to unregister every DAI it finds
for the component rather than trying to unregister one DAI for each DAI that was
registered. Both have the same result since there won't be more DAIs than what
have been registered, but the former is easier to implement.

      ASoC: Consolidate enum and value enum controls · 29ae2fa5
      由 Lars-Peter Clausen 提交于 
      The implementations for enum and value enum controls are almost identical. The
only difference is that the value enum uses an additional look-up table to map
the control value to the register value, while the enum control uses a direct
mapping. Enums and value enums can easily be distinguished at runtime, for value
enums the values field of the snd_soc_enum struct contains the look-up table,
while for enums it is NULL. This patch adds two new small helper functions
called snd_soc_enum_item_to_val() and snd_soc_enum_val_to_item() which map
between register value and control item. If the items field of the snd_soc_enum
struct is NULL the function will do a direct mapping otherwise they'll use the
look-up table to do the mapping. Using these small helper functions it is
possible to use the same kcontrol handlers for both enums and value enums. The
functions are added a inline functions in soc.h so they can also be used by the
DAPM code to accomplish similar consolidation.

      ASoC: core: Set the default I/O up try regmap. · fe2265e4
      由 Xiubo Li 提交于 
      For most CODEC drivers which the REGMAP is used, the soc_probe_codec()
will do the stuff work of snd_soc_codec_set_cache_io(), which the CODEC
drivers' ASoC probe will do too, and almost at the same time.

This patch set the default I/O up try regmap, and then the CODEC drivers'
stuff work of snd_soc_codec_set_cache_io() will be redundant, while if one
CODEC driver needed to set it's own I/O, then it can rewrite the default ones.
Then could we just discard the snd_soc_codec_set_cache_io() from the CODEC
drivers' ASoC probe to simplify the code.

      ASoC: core: add TDM slot parsing from DT supports · 89c67857
      由 Xiubo Li 提交于 
      For some CPU/CODEC DAI devices the TDM slot infomation maybe needed. This
patch adds the slot parsing from DT supports.

TDM slot properties:
    dai-tdm-slot-num : Number of slots in use.
    dai-tdm-slot-width :  Width in bits for each slot.

For instance:
    dai-tdm-slot-num = <2>;
    dai-tdm-slot-width = <8>;

And for each spcified driver, there could be one .of_xlate_tdm_slot_mask()
to specify a explicit mapping of the channels and the slots. If it's absent
the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the
tx and rx masks.

For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit
for an active slot as default, and the default active bits are at the LSB of
the masks.
