| * ASoC: io: New signature for snd_soc_codec_set_cache_io()Xiubo Li2014-03-111-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | Now that all users have been converted to regmap and the config.reg_bits and config.val_bits can be setted by each user through regmap core API. So these two params are redundant here. Since the only control type that left is SND_SOC_REGMAP, so remove it. Drop the control params and add struct regmap *regmap to simplify the code.

* / ASoC: Rename soc_enum.max field with itemsTakashi Iwai2014-02-201-2/+2
|/ | | | | | | | | | | | | | | | | | The name "max" in struct soc_enum is rather confusing since it actually takes the number of items. 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.

| * ASoC: wm8994: Simplify button detection codeMark Brown2012-12-031-50/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the WM8994 driver allows the WM8958 microphone detection code to be replaced in its entirety, providing a default implementation. This doesn't actually reflect the needs of users well. They generally wish to replace only the accessory identification parts of the algorithm (eg, using an external GPIO to provide the equivalent of the JACKDET support in the WM1811A). In preparation for supporting these users better refactor the existing code so that we have separate identification and button detection callbacks, selecting between them rather than using the mic_detecting flag in the existing callback. This also simplifies the code by introducing a more explicit state machine for the detecting and button states. In anticipation of future refactoring the callback is left in the signature for wm8958_mic_detect(), it will be removed at a later stage.
