This patch adds generic signed register volume control logic to soc-core. Instead of a fixed width signed register control, this implementation uses a 'min' value and the signed bit location to translate it to an absolute volume. Using the 'sign_bit' we can calculate a correct mask for the register values and translate it back into signed integers of standard size.

With "max", one might try to assign (nitems - 1) value. Rename the field to a more appropriate one, "items", which is also used in struct snd_ctl_elem_info, too. This patch also rewrites some code like "if (x > e->nitems - 1)" with "if (x >= e->nitems)". Not only the latter improves the readability, it also fixes a potential bug when e->items is zero.

This patch adds unlocked versions of all the functions replacing the existing implementations with one that holds the lock internally. We also fix up the places where the lock was actually held on the caller side.

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.

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.

This patch uses snd_soc_enum_item_to_val() and snd_soc_enum_val_to_item(), which where earlier introduced during the consolidation of enum and value enum controls, to hide this difference. This allows us to use the same code path for both MUXs and value MUXs and a lot of nearly duplicated code can be removed.

This patch adds code, which is similar to what we already do for DAPM mixer controls to support virtual mixer controls, to DAPM enum controls. The new code will check if the enum does a hardware backing register and skip over reading and writing to the register if it has not. This allows us to use the same code path for both MUXs and virtual MUXs and a lot of nearly identical code can be removed.
