2016-02-20ASoC: qcom: add mic supportSrinivas Kandagatla2-76/+204
This patch adds mic support to the lpass driver, most of the driver is reused as it is, only the register level access is changed depending on te direction of the stream.

2016-02-20ASoC: qcom: add generic bit masks for RDMA and WRDMASrinivas Kandagatla2-58/+79
This patch adds generic masks for accessing bits in rdma/wrdma registers. Doing this would simplify the driver and adding capture support would be much simpler. Also there is no point in having same bit masks for bits in both rdma and wrdma registers. This patch also deletes the RDMA specific bit masks and makes the code use the generic bit masks.

2016-02-20ASoC: qcom: rename rdma_ch_bit_map to dma_ch_bit_mapSrinivas Kandagatla2-4/+4
rdma_ch_bit_map can be reused for wrdma channel allocations as wrdma channel numbering start after rdma channel numbers. With capture support referring rdma_ch_bit_map for wrdma channel allocation is confusing, so renaming rdma_ch_bit_map to dma_ch_bit_map makes sense.

2016-02-20Merge tag 'asoc-fix-v4.5-rc4' into asoc-qcomMark Brown50-335/+759
ASoC: Fixes for v4.5 A rather large batch of fixes here, almost all in the Intel driver. The changes that got merged in this merge window for Skylake were rather large and as well as issues that you'd expect in a large block of new code there were some problems created for older processors which needed fixing up. Things are largely settling down now hopefully.

2016-02-18ALSA: oxfw: use workqueue instead of tasklet for scs1xTakashi Sakamoto1-6/+6
This commit replaces tasklet with workqueue for scs1x functionality of ALSA oxfw driver. This driver transfers MIDI message specific for SCS.1m and SCS.1d. This task is currently done in software IRQ context of tasklet. In a view of system, this context is limited resources and some important drivers (at least, more important than ALSA oxfw driver) use the context as its bottom-harf. If the work to transfer MIDI messages is done within a time, it's better to use the other context for the work. Actually, with recent CPUs, the work will be scheduled within a time.

2016-02-18ALSA: pcm: Fix rwsem deadlock for non-atomic PCM streamTakashi Iwai1-2/+14
A non-atomic PCM stream may take snd_pcm_link_rwsem rw semaphore twice in the same code path, e.g. one in snd_pcm_action_nonatomic() and another in snd_pcm_stream_lock(). Usually this is OK, but when a write lock is issued between these two read locks, the problem happens: the write lock is blocked due to the first reade lock, and the second read lock is also blocked by the write lock. This eventually deadlocks. The reason is the way rwsem manages waiters; it's queued like FIFO, so even if the writer itself doesn't take the lock yet, it blocks all the waiters (including reads) queued after it. As a workaround, in this patch, we replace the standard down_write() with an spinning loop. This is far from optimal, but it's good enough, as the spinning time is supposed to be relatively short for normal PCM operations, and the code paths requiring the write lock aren't called so often.

Modify portman driver to use the new parallel port device model. The advantage of using the device model is that the device gets binded to the hardware, we get the feature of hotplug, we can bind/unbind the driver at runtime. The changes are in the way the driver gets registered with the parallel port subsystem and the temporary device to probe portman card is removed and portman_probe() is used in the probe callback.

The commit [7f0973e973cd: ALSA: seq: Fix lockdep warnings due to double mutex locks] split the management of two linked lists (source and destination) into two individual calls for avoiding the AB/BA deadlock. However, this may leave the possible double deletion of one of two lists when the counterpart is being deleted concurrently. It ends up with a list corruption, as revealed by syzkaller fuzzer.

Last patch added infrastructure to render over all the ports, PCM<->cvt<- pin mapping and user selection of controls. But we still have restriction of playback on the default port alone, so remove that. This patch removes the hardcoding of cvt<->pin map from the dai. Cvt and pin for a dai are now derived from the already stored pcm list of device opened. We query connection list of a pin from codec to validate the cvt<->pin map.

2016-02-15ASoC: hdac_hdmi: Add jack reportingJeeja KP2-3/+163
Jack is created based on pcm devices enumerated, so we will create Jack as "HDMI/DP, pcm=x Jack". This style is expected by current usermode like PulseAudio and CRAS. This patch exports an API which can be used to register Jack based on PCM. This API also establishes the map between PCM and cvt. Further cvt to pin mapping is established with the help of usermode selection based on the board topology. During device probe as the PCMs may not be registered, initial pin sense don't report jack events. So, first time jack reporting is done during user selection of mux control.

2016-02-15ASoC: hdac_hdmi: Create widget/route based on nodes enumeratedSubhransu S. Prusty1-22/+219
In skylake, HDMI codec enumerates 3 pins and 3 cvts. Stream can be routed from any cvt to any pin based on the connection list queried from the pin. This patch removes the static modelling of widget/route and creates it dynamically based on the codec widgets enumerated. Mux widgets are added to represent the map between a cvt and pin. Ideally the mux widgets should be created based on the connection list queried from the pin widget. But due to HW behavior, if an external display is not connected on a port, querying the connection list returns zero. So create mux widgets to map all the cvt to all pins. At runtime, playback support on a pin can be verified based on the connection list query. Few function in driver have additional arguments now to support this. Signed-off-by: Subhransu S.
