Merge series "Qualcomm's lpass-hdmi ASoC driver to support audio over dp port" from Srinivasa Rao Mandadapu <srivasam@codeaurora.org>:
These patches are to support audio over DP port on Qualcomm's SC7180 LPASS Asoc. It includes machine driver, cpu driver, platform driver updates for HDMI path support, device tree documention, lpass variant structure optimization and configuration changes. These patches depends on the DP patch series https://patchwork.kernel.org/project/dri-devel/list/?series=332029 https://lore.kernel.org/patchwork/project/lkml/list/?series=464856 changes since V10: -- Moved hdmi regmap functions from lpass-hdmi.c to lpass-cpu.c -- Moved QCOM_REGMAP_FIELD_ALLOC macro from lpass-hdmi.c to lpass.h changes since V9: -- Removed unused structures lpass_hdmi.h changes since V8: -- Removed redundant structure wrapper for reg map field memebrs -- Updated lpass_hdmi_regmap_volatile API with appropriate registers as true and others as false. changes since V7: -- Fixed typo errors -- Created Separate patch for buffer size change changes since V6: -- Removed compile time define flag, which used for enabling HDMI code, based on corresponding config param is included. -- Updated reg map alloc API with reg map bulk API. -- Removed unnecessary line splits changes since V5: -- Removed unused struct regmap *map in lpass_platform_alloc_hdmidmactl_fields. -- DMA alloc and free API signature change in lpass-apq8016.c, lpass-ipq806x.c -- Keeping API "irqreturn_t lpass_platform_hdmiif_irq" under ifdef macro Changes Since v4: -- Updated with single compatible node for both I2S and HDMI. Changes Since v3: -- Removed id in lpass variant structure and used snd_soc_dai_driver id. Changes Since v2: -- Audio buffer size(i.e. LPASS_PLATFORM_BUFFER_SIZE) in lpass-platform.c increased. Changes Since v1: -- Commit messages are updated -- Addressed Rob Herring review comments V Sujith Kumar Reddy (7): ASoC: Add sc7180-lpass binding header hdmi define ASoC: dt-bindings: Add dt binding for lpass hdmi Asoc:qcom:lpass-cpu:Update dts property read API Asoc: qcom: lpass:Update lpaif_dmactl members order ASoC: qcom: Add support for lpass hdmi driver Asoc: qcom: lpass-platform : Increase buffer size ASoC: qcom: sc7180: Add support for audio over DP .../devicetree/bindings/sound/qcom,lpass-cpu.yaml | 74 ++-- include/dt-bindings/sound/sc7180-lpass.h | 1 + sound/soc/qcom/Kconfig | 5 + sound/soc/qcom/Makefile | 2 + sound/soc/qcom/lpass-apq8016.c | 4 +- sound/soc/qcom/lpass-cpu.c | 249 ++++++++++++- sound/soc/qcom/lpass-hdmi.c | 258 ++++++++++++++ sound/soc/qcom/lpass-hdmi.h | 102 ++++++ sound/soc/qcom/lpass-ipq806x.c | 4 +- sound/soc/qcom/lpass-lpaif-reg.h | 49 ++- sound/soc/qcom/lpass-platform.c | 395 +++++++++++++++++---- sound/soc/qcom/lpass-sc7180.c | 116 +++++- sound/soc/qcom/lpass.h | 124 ++++++- 13 files changed, 1240 insertions(+), 143 deletions(-) create mode 100644 sound/soc/qcom/lpass-hdmi.c create mode 100644 sound/soc/qcom/lpass-hdmi.h -- Qualcomm India Private Limited, on behalf of Qualcomm Innovation Center, Inc., is a member of Code Aurora Forum, a Linux Foundation Collaborative Project.
