This patch set is required for HDMI audio support on HiKey. This patchset hasn't yet seen the light of lkml, so I suspect there will be a few revisions, but I wanted to send it out for an initial review.
The work is mostly that of Andy Green's, but I've taking a swing at forward porting and cleaning it up where I saw fit. So credit to Andy and blame to me. Apologies in advance, as I'm not super familiar with either DMA or ASoC driver. The one bit missing to have audio fully working is changes to the adv7511 driver, but most of those changes are still out of tree, so I'll submit those changes once they land. Feedback would be very much appreicated! thanks -john Cc: Zhangfei Gao <zhangfei....@linaro.org> Cc: Jingoo Han <jg1....@samsung.com> Cc: Krzysztof Kozlowski <k.kozlow...@samsung.com> Cc: Maxime Ripard <maxime.rip...@free-electrons.com> Cc: Vinod Koul <vinod.k...@intel.com> Cc: Dan Williams <dan.j.willi...@intel.com> Cc: Liam Girdwood <lgirdw...@gmail.com> Cc: Mark Brown <broo...@kernel.org> Cc: Jaroslav Kysela <pe...@perex.cz> Cc: Takashi Iwai <ti...@suse.com> Cc: Wei Xu <xuw...@hisilicon.com> Cc: Rob Herring <robh...@kernel.org> Cc: Andy Green <a...@warmcat.com> Cc: Dave Long <dave.l...@linaro.org> Cc: Guodong Xu <guodong...@linaro.org> Andy Green (5): k3dma: Fix hisi burst clipping k3dma: Fix dma err offsets k3dma: Fix "nobody cared" message seen on any error k3dma: Add cyclic mode for audio ASoC: hisilicon: Add hi6210 i2s audio driver for hdmi audio John Stultz (2): Kconfig: Allow k3dma driver to be selected for more then HISI3xx platforms dts: hi6220: Add k3-dma and i2s/hdmi audio support arch/arm64/boot/dts/hisilicon/hi6220.dtsi | 36 ++ drivers/dma/Kconfig | 1 - drivers/dma/k3dma.c | 149 ++++++- sound/soc/Kconfig | 1 + sound/soc/Makefile | 1 + sound/soc/hisilicon/Kconfig | 5 + sound/soc/hisilicon/Makefile | 2 + sound/soc/hisilicon/hi6210-hdmi-card.c | 131 ++++++ sound/soc/hisilicon/hi6210-i2s.c | 641 ++++++++++++++++++++++++++++++ sound/soc/hisilicon/hi6210-i2s.h | 276 +++++++++++++ 10 files changed, 1222 insertions(+), 21 deletions(-) create mode 100644 sound/soc/hisilicon/Kconfig create mode 100644 sound/soc/hisilicon/Makefile create mode 100644 sound/soc/hisilicon/hi6210-hdmi-card.c create mode 100644 sound/soc/hisilicon/hi6210-i2s.c create mode 100644 sound/soc/hisilicon/hi6210-i2s.h -- 1.9.1
