2013-03-12ENGR00234501 ASoC: spdif: fix Ubuntu reboot hang issueNicolin Chen
spdif driver registered kcontrol for ALSA subsystem controlling, while some of those kcontrol functions lack of clk_enable() before register-accessing. So system would definitely hang when those functions're called, which did happen during reboot test on Ubuntu due to its pulse-audio. This patch added paired clk_en/disable() to those functions so as to pevent system hang issue.

2013-03-08ENGR00253290-2 ASoC: imx-wm8962: fix continuous playback distortion issueNicolin Chen
If DAC volume's set to a value that's lower than 0xd8, contineously FLL setting of wm8962 in machine driver would cause playback distortion issue, which happens to ENGR219882. so we have to put some another code in machine driver to prevent distortion issue.

2013-03-08ENGR00253290-1 ASoC: wm8962: fix over-gained audio playback issueNicolin Chen
We put some code to set default volumes in codec driver, but later we found that one of volume was higher than 0db, which would cause over-gained volume. So this patch removed DAC default volume setting, and reverted the volume interface of it to let user control the register from user space.

Patch ENGR00233056 added DMABUF size setting for hw_param and changed SSI's buffer allocating size. But didn't add allocation for ESAI and SPDIF, which might cause some dma transmitting issue.

2012-11-15ENGR00233663 HDMI: add support for ALSA DMIXChen Liangjun
when using DMIX for ALSA playback, ALSA would not update write index into driver but maintain it in ALSA LIB level. However, HDMI driver need write index for HDMI header packing. In this case, HDMI driver would fail to do HDMI header pack and user hear no sound when using DMIX in HDMI audio playback. In this patch, use read index(hw_ptr) for HDMI header packing.

HDMI driver can be divided into 3 parts: machine driver, platform driver, codec driver.To support HDMI AUDIO loadable module build, HDMI machine driver should be built as loadable.

HDMI hardware fix: signal of HDMI DMA DONE is hard connected to SDMA event line. SDMA event is triggered by edge.

2012-09-14ENGR00224245 HDMI AUDIO: stop/start PCM while unplug,blank/plug, unblankChen Liangjun
When unplug, blank happens, HDMI audio can't play properly. So in driver, audio pcm would be disconnected when event above happens. However, pulse audio can't process disconnect event properly and if an blank or unplug event happens, HDMI sink would lost and can't be back again. In this patch, instead of disconnecting audio PCM stream, triggering stop audio pcm while unplug and blank, triggering start again while plug and unblank if the audio pcm is triggerd stop in the unplug/blank event.

2012-09-13ENGR00223816 HDMI AUDIO: fix kernel panic cause by accessing unavailable memoryChen Liangjun
HDMI audio driver is responsible for add IEC header into audio sample. In HDMI audio driver, a variable named rtd->appl_bytes is maintained to stand for how many audio sample have already processed. appl_bytes stands for how many audio sample the user space have already feed into kernel driver. So we use the connt = appl_bytes - rtd->appl_bytes to decide how many data need to be processed. And the processed data would be write into an preallocated buffer called hw_buf in driver. When doing seek operation, the appl_bytes changes in an wide range. So it is possible that the count value is far larger than the size of hw_buf and the memory access un-existed address error would happens. In this patch, Add check operation for count to avoid kernel panic.

When use no ideal-ratio mode for ESAI playback, CPU should provide accurate clock for input clock, which means input clock should be divided by input sample rate. However, all our clock is from 24M crystal and if the input sample rate equal to 44.1k or so, CPU can't provide these clock.

2012-08-16ENGR00219931 ESAI ASRC: fix channel swap bug while playback 6 channelChen Liangjun
Channel swap caused by 2 reason: 1. To avoid ASRC underflow error, ASRC driver would prefill ASRC input FIFO with 160 samples. However, 160 can't be divided by 6. In this case, channel data miss alignment. In this patch, prefill ASRC input FIFO with 120, which can be divided by 2,4,6,8. 2. While start P2P playback, ESAI driver would first start SDMA, then ASRC, and last ESAI. While start ESAI, the data is not ready, thus ESAI underrun would happens and channel data miss alignment. In this patch, delay 1 ms between ASRC's start and ESAI's start. Signed-off-by: Chen Liangjun <b36089@freescale.com>

2012-08-01ENGR00218958 ESAI ASRC: fix system hang cause by accessing ASRC with no clockChen Liangjun
In ESAI_ASRC, to use ASRC for p2p playback, ESAI driver would maintain an variable to keep track of ASRC pair number allocated. So every time ESAI driver want to use ASRC, he would first init the variable to a value (0 in ESAI driver)stand for unvalid pair number and then request an valid pair number. At last, open the ASRC clock for ASRC register access. However, ASRC driver treat 0 as an valid pair number. Thus, if an ESAI ASRC playback is failed, ESAI driver would check whether the pair number is valid. If the pair number is valid, ESAI driver would access ASRC register to do some clean work. Thus, the init 0 value would be treat as an valid pair number and ASRC register would be access without ASRC clock. In the case, an system hang happens. In this patch, init pair number variable to -1 after its allocation. Signed-off-by: Chen Liangjun <b36089@freescale.com>

2012-07-30ENGR00218807 ESAI: fix bootup issue cause by accessing unexist addressChen Liangjun
To support p2p playback, ESAI driver would copy platform data to esai_asrc struct. The platform data only exist on boards that supports ESAI. However, for ARM2 board, it supports ESAI but not necessary get the codec CS42888. Thus the probe() in ESAI driver would also try to copy the platform data from board init file. The p2p playback now only support ARD board, so the ESAI probe() for ARM2 would access unexisted address and cause an kernel dump. In the patch, check the platform data address before copy.

In the origin code, ESAI driver supoprt audio p2p playback by setting input PCM data's sample rate thought amixer interface.It is ugly and request user application call amixer control interface everytime before and playback. In this patch, user can call the audio p2p playback by writing data to an special virtual device. Driver would automatically get the params of input PCM. At the same time, driver would get the output sample rate and word data. With the data abover, driver can set ASRC properly and audio p2p palyback is support. This patch mainly focus on: 1 clean old p2p playback way for ESAI. 2 Setup the output sample rate and word width to virtual device's substream_runtime's private data. Everytime the virtual device is called, the data abover is used for config ASRC, ESAI, and codec. Signed-off-by: Chen Liangjun <b36089@freescale.com>
