2014-07-23ENGR00324009 Revert "ENGR00323404-1 ASoC: fsl_sai: Reset FIFOs after ↵Nicolin Chen
disabling TE/RE" Patch "ASoC: fsl_sai: Reset FIFOs after disabling TE/RE" may accidentally increase the underrun rate of SAI. To keep an equal quality as previous release, we decide to revert this patch and find a thorough way to reset the FIFO later. This reverts commit b85f840a60de8d0a5ca8fbe7eda15f611ff5b622.

2014-07-14ALSA: usb-audio: Fix deadlocks at resumingTakashi Iwai
The recent addition of the USB audio mixer suspend/resume may lead to deadlocks when the driver tries to call usb_autopm_get_interface() recursively, since the function tries to sync with the finish of the other calls. For avoiding it, introduce a flag indicating the resume operation and avoids the recursive usb_autopm_get_interface() calls during the resume.

2014-07-14ALSA: usb-audio: Save mixer status only once at suspendTakashi Iwai
The suspend callback of usb-audio driver may be called multiple times per suspend when multiple USB interfaces are bound to a single sound card instance. In such a case, it's superfluous to save the mixer values multiple times. This patch fixes it by checking the counter. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2014-05-13ASoC: core: Add signed register volume control logicMarkus Pargmann
Some codecs use signed volume control representation with non standard register sizes, e.g. 6 or 7 bit signed integers. 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.

The sysclk, which could be connected to IPG clock, is one of the eight clocks on the inner clock mux of SPDIF. Previously we forbade the usage of this clock due to imperfect clock selecting function. This patch adds the sysclk_df divisor so as to complete sysclk function. [ In order to potect those clocks from other modules and the situation when SPDIF root clock is shared with other module (ASRC on imx6sx for example) that demands us to fix the clock and not to change its rate, starting from now on, we no longer use clk_round() and clk_set_rate(). ] Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com>
