They have the same codes for managing this buffer. Moving this to the core/pcm files so that they can use that directly. Remove the code from Tegra PCM and use these new library function. This is enabled only for ARM specific and can be extended to other architecture if they support the writecombine dma buffer. This patch is based on detail discussion on patch: [PATCH] ASoC: snd_dmaengine: add common api for pcm_mmap And suggestion from Lars and Takashi. Laxman Dewangan (3): ALSA: pcm: add apis for writecombine dma buffer allocation ASoC: add apis for creating/free pcm dma buffer ASoC: tegra: use core/pcm library for pcm buffer allocation include/sound/pcm.h | 17 ++++++++ include/sound/soc.h | 13 ++++++ sound/core/pcm_native.c | 53 +++++++++++++++++++++++++ sound/soc/soc-core.c | 50 +++++++++++++++++++++++ sound/soc/tegra/tegra_pcm.c | 92 ++----------------------------------------- 5 files changed, 137 insertions(+), 88 deletions(-)
