2016-08-11ASoC: mediatek: mark symbols static where possibleBaoyou Xie
We get 2 warnings about global functions without a declaration in the ASoC mediatek module when building with W=1: sound/soc/mediatek/common/mtk-afe-fe-dai.c:26:5: warning: no previous prototype for 'mtk_regmap_update_bits' [-Wmissing-prototypes] int mtk_regmap_update_bits(struct regmap *map, int reg, unsigned int mask, ^ sound/soc/mediatek/common/mtk-afe-fe-dai.c:34:5: warning: no previous prototype for 'mtk_regmap_write' [-Wmissing-prototypes] int mtk_regmap_write(struct regmap *map, int reg, unsigned int val) In fact, all of those functions are only used in the file in which they are declared and don't need a declaration, but can be made static. so this patch marks it 'static'.

2015-12-22ASoC: mediatek: Turn AFE on/off in runtime resume/suspendKoro Chen
AFE is actually allowed to be turn on before configuration of DAIs since each DAI has its own enabling control. Turn on/off AFE in runtime resume/suspend to avoid AFE being shut down when closing a DAI while other DAIs are still active.

2015-12-08ASoC: mediatek: Use current HW pointer for pointer callbackKoro Chen
Previously we recorded "last interrupt position" and used it in pointer callback. This is not correct implementation, and it causes underruns when user space monitors buffer level to decide when to send next data chunk in low latency application. Remove position recording in IRQ handler and also hw_ptr in struct mtk_afe_memif used to record that, and let pointer callback reports current HW pointer instead.

2015-09-14ASoC: mediatek: Increase periods_min in captureKoro Chen
In capture, there is chance that hw_ptr reported at IRQ is a little smaller than period_size due to internal AFE buffer. In the case of ping-pong buffer: |xxxxxxxxxxxxxxxxxxxxxxxxxxxx--|-----------------------------| hw_ptr < period_size This available buffer will not be read since its size is smaller than avail_min (which is period_size by default), and read thread continues to sleep. If the next hw_ptr is just a little larger than buffer_size, overrun occurs. One more period can hold the possible unread buffer.

2015-08-17ASoC: mediatek: Remove AIF widgets for backend DAIsKoro Chen
DAPM core already creates widgets for DAIs. It is not necessary to declare them by SND_SOC_DAPM_AIF_IN/SND_SOC_DAPM_AIF_OUT. Furthermore, original codes use backend DAI's stream name to be the AIF widget name. It causes the same widget to be created twice, and after commit 92fa12426741 ("ASoC: dapm: Add new widgets to the end of the widget list") the first created widget (by snd_soc_dapm_new_controls) is used, not the 2nd created one (by snd_soc_dapm_new_dai_widgets), so audio path is broken.

This adds suspend/resume callbacks, which are common for each DAI.
