      ENGR00233731 ALSA: add DMABUF allocating for different driver · fbd07a2c
      Nicolin Chen authored
       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.
       This Patch add new allocation code that detects the driver before allocating
      its DMABUF.

      ENGR00233577 ASRC: add spinlock to protect ASRC pair resource · bbdb7813
      Chen Liangjun authored
      when quit from ASRC driver with CTRL + C, driver close() would free
      output buffer and close clock. However, it is possible that the buffer
      is accessed by work task(work task is trigger by interrupt and it would
      not be stopped by CTRL + C). So ASRC driver should promise that  its
      pair resource(buffer, SDMA channel, and clock) would not be accessed
      after it is released.
      In this patch, add protect for pair resource.

      ENGR00233728 mx6 usb: change usb driver load from arch_initcall to module_init · 3042d8dc
      make shi authored
      We should use module_init as usb driver initialization entry point.
      To avoid the following crash when sabreauto board bootup:

      pgd = 80004000

      Some board for example sabreauto board usb power gpio is use a io
      i2c expander gpio, gpio i2c driver load use subsys_initcall as driver
      initialization entry point, so gpio is not accessible at early bootup.

      ENGR00233663 HDMI: add support for ALSA DMIX · 6b9084c3
      Chen Liangjun authored
      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.
