* | ASoC: wm0010: Use WARN_ON() instead of BUG_ON()Takashi Iwai2013-11-061-1/+2
|/ | | | | | | Use WARN_ON() and handle the error cases accordingly. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: wm0010: Use DMA-safe memory for SPI transfersDimitris Papastamos2013-08-011-6/+6
| | | | | | | | We should be allocating our buffers for the SPI transfers from the DMA zone. Signed-off-by: Dimitris Papastamos <dp@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: wm0010: Fix resource leakDimitris Papastamos2013-07-311-12/+12
| | | | | | | | | If kzalloc() fails for `img' then we are going to leak the memory for `out'. We are freeing the memory of all the tx/rx transfers but the tx/rx buf pointers will be NULL if we drop out earlier.

* ASoC: wm0010: Clear IRQ as wake source and include missing headerCharles Keepax2013-06-031-0/+3
| | | | | | | | Both clear the IRQ as being a wake source when we are finished with it and include a missing header file that is required. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: wm0010: Set IRQ as a wake sourceCharles Keepax2013-05-301-0/+7
| | | | | | | | | The DSPs IRQ should be a wake source as several of the possible algorithms may run whilst the AP is asleepi and require to wake the AP to push or pull more data, such as compressed playback.

| | | | | | | | | | | | | | | | Fix to return -ENOMEM in the memory malloc of 'out' and 'img_swap' error handling case instead of 0, as done elsewhere in this function. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* ASoC: codecs: remove __dev* attributesBill Pemberton2012-12-091-3/+3
| | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit.

* ASoC: wm0010: Ignore interrupts in power down modeMark Brown2012-11-271-1/+0
| | | | | | | The device should not be generating interrupts when it does not have power so ignore incoming interrupts. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: wm0010: Add checking for .dfw info record version.Scott Ling2012-11-231-1/+24
| | | | | | | | | | | The info record at the start of the dsp firmware file has been expanded to incorporate additional version information. We need to check the version to make sure we understand the layout of the information in the record. The srec2image tool is currently used to create this record during creation of the .dfw file.

* ASoC: wm0010: Allow slow GPIO for resetMark Brown2012-09-261-3/+5
| | | | | | | We never set the GPIO from atomic context so there's no reason why we can't support a GPIO that needs to sleep when configuring. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

The WM0010 is a compact digital signal processor that has been highly optimised for low-power audio applications. Extensive memory resources and core optimisation allow the device to manage all audio processing algorithms efficiently and autonomously, while the host processor sleeps or performs other tasks.
