[PATCH] ASoC: fsl_spdif: Fix unexpected interrupt after suspend
by Shengjiu Wang 23 Jun '21

23 Jun '21

When system enter suspend, the machine driver suspend callback function will be called, then the cpu driver trigger callback (SNDRV_PCM_TRIGGER_SUSPEND) be called, it would disable the interrupt. But the machine driver suspend and cpu dai driver suspend order maybe changed, the cpu dai driver's suspend callback is called before machine driver's suppend callback, then the interrupt is not cleared successfully in trigger callback. So need to clear interrupts in cpu dai driver's suspend callback to avoid such issue.

[PATCH v2 00/12] drm/vc4: hdmi: Enable Channel Mapping, IEC958, HBR Passthrough using hdmi-codec
by Maxime Ripard 23 Jun '21

23 Jun '21

Hi, hdmi-codec allows to have a lot of HDMI-audio related infrastructure in place, it's missing a few controls to be able to provide HBR passthrough. This series adds more infrastructure for the drivers, and leverages it in the vc4 HDMI controller driver. Thanks! Maxime Changes from v1: - Added an extra patch to clarify the iec958 controls iface policy - Added kerneldoc for the new iec958 PCM functions - s/EXPORT_SYMBOL/EXPORT_SYMBOL_GPL - Used the ALSA prefix where relevant - Rebased on drm-misc-next-2021-05-17 Dom Cobley (5): drm/vc4: hdmi: Set HD_CTL_WHOLSMP and HD_CTL_CHALIGN_SET drm/vc4: hdmi: Set HDMI_MAI_FMT drm/vc4: hdmi: Set VC4_HDMI_MAI_CONFIG_FORMAT_REVERSE drm/vc4: hdmi: Remove firmware logic for MAI threshold setting ARM: dts: bcm2711: Tune DMA parameters for HDMI audio Maxime Ripard (7): ALSA: doc: Clarify IEC958 controls iface ALSA: iec958: Split status creation and fill ASoC: hdmi-codec: Rework to support more controls ASoC: hdmi-codec: Add iec958 controls ASoC: hdmi-codec: Add a prepare hook drm/vc4: hdmi: Register HDMI codec drm/vc4: hdmi: Remove redundant variables .../kernel-api/writing-an-alsa-driver.rst | 13 +- arch/arm/boot/dts/bcm2711.dtsi | 4 +- drivers/gpu/drm/vc4/Kconfig | 1 + drivers/gpu/drm/vc4/vc4_hdmi.c | 322 ++++++++---------- drivers/gpu/drm/vc4/vc4_hdmi.h | 5 +- drivers/gpu/drm/vc4/vc4_regs.h | 30 ++ include/sound/hdmi-codec.h | 12 +- include/sound/pcm_iec958.h | 8 + sound/core/pcm_iec958.c | 176 +++++++--- sound/soc/codecs/hdmi-codec.c | 219 +++++++++--- 10 files changed, 508 insertions(+), 282 deletions(-) -- 2.31.1
