Merge series "ASoC: SOF: small fixes for 5.10" from Kai Vehmanen <kai.vehmanen@linux.intel.com>:
Series that adds debug support for IMX platforms, more details to FW version information, adds missing -EACCESS handling to pm_runtime_get_sync() calls and a set of minor cosmetic, trace verbosity and coding style issues. Guennadi Liakhovetski (3): ASoC: SOF: (cosmetic) remove redundant "ret" variable uses ASoC: SOF: remove several superfluous type-casts ASoC: SOF: fix range checks Iulian Olaru (1): ASoC: SOF: imx: Add debug support for imx platforms Karol Trzcinski (1): ASoC: SOF: Add `src_hash` to `sof_ipc_fw_version` structure Pierre-Louis Bossart (3): ASoC: SOF: debug: update test for pm_runtime_get_sync() ASoC: SOF: control: update test for pm_runtime_get_sync() ASoC: SOF: Intel: hda: reduce verbosity of boot error logs include/sound/sof/info.h | 4 +- sound/soc/sof/control.c | 62 +++++++++++++-------------- sound/soc/sof/debug.c | 2 +- sound/soc/sof/imx/Kconfig | 8 ++++ sound/soc/sof/imx/Makefile | 3 ++ sound/soc/sof/imx/imx-common.c | 72 ++++++++++++++++++++++++++++++++ sound/soc/sof/imx/imx-common.h | 16 +++++++ sound/soc/sof/imx/imx8.c | 23 +++++++++- sound/soc/sof/imx/imx8m.c | 17 +++++++- sound/soc/sof/intel/hda-loader.c | 16 +++---- sound/soc/sof/intel/hda.c | 12 ++++-- sound/soc/sof/intel/hda.h | 2 + sound/soc/sof/sof-audio.c | 6 +-- sound/soc/sof/sof-priv.h | 8 ++++ sound/soc/sof/topology.c | 44 ++++++++++--------- 15 files changed, 226 insertions(+), 69 deletions(-) create mode 100644 sound/soc/sof/imx/imx-common.c create mode 100644 sound/soc/sof/imx/imx-common.h -- 2.27.0
