      ALSA: dice: Split transaction functionality into a file · 7c2d4c0c
      由 Takashi Sakamoto 提交于 
      This commit adds a file with some helper functions for transaction, and move
some codes into the file with some arrangements.

For Dice chipset, well-known FCP or AV/C commands are not used to control
devices. It's achieved by read/write transactions into specific addresses.

Dice's address area is split into 5 areas. Each area has its own role. The
offset for each area can be got by reading head of the address area. By
reading these areas, drivers can get to know device status. By writing these
areas, drivers can change device status.

Dice has a specific mechanism called as 'notification'. When device status is
changed, Dice devices tells the event by sending transaction. This notification
is sent to an address which drivers register in advance. But this causes an
issue to drivers.

To handle the notification, drivers need to allocate its own callback function
to the address region in host controller. This region is exclusive. For the
other applications, drivers must give a mechanism to read the received
notification. For this purpose, Dice driver already implements hwdep interface.

Dice chipset doesn't allow drivers to register several addresses. In this
reason, when this driver is applied to a device, the other drivers should
_not_ try to register its own address to the device.

      ALSA: dice: Move file to its own directory · 14ff6a09
      由 Takashi Sakamoto 提交于 
      In followed commits, dice driver is split into several files. For easily
managing these files, this commit adds subdirectory and move file into
the directory.

      ALSA: dice: Rename structure and its members · 732d153f
      由 Takashi Sakamoto 提交于 
      Currently, dice driver supports AMDTP out-stream. In followed commits, AMDTP
in-stream will be supported but current name of members in dice structure
are not propper. This commit renames these members to proper name.

Additionally, for easily distinguishing local symbols from structure tag,
rename dice tag into snd_dice.

      ALSA: hda - Allow forcibly enabling/disabling snoop · 7c732015
      由 Takashi Iwai 提交于 
      User can pass snoop option to enable/disable the snoop behavior, but
currently azx_check_snoop_available() always turns it off for some
devices.  For better debuggability, change the parameter as bint, and
allow user to enable/disable forcibly the snoop when specified via the
module option.

      ALSA: hda - Add AZX_DCAPS_SNOOP_OFF (and refactor snoop setup) · 37e661ee
      由 Takashi Iwai 提交于 
      Add a new driver_caps bit, AZX_DCAPS_SNOOP_OFF, to set the snoop off
as default.  This new bit is used for the checks in
azx_check_snoop_available().  Most of case-switches are replaced with
the new dcaps in each entry.

While working on it, for avoiding to spend more bits, combine three
bits AZX_DCAPS_SNOOP_SCH, AZX_DCAPS_SNOOP_ATI and
AZX_DCAPS_SNOOP_NVIDIA bits into a flat type of two bits.  This
reduces the bits usages, and assign AZX_DCAPS_OFF to this empty bit
now.
