You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

So I'm very surprised that you successfully tested this on DB410c. Attempting to play HDMI audio results in: ADV7533: lpass_platform_pcmops_hw_params: invalid interface: 3 ADV7533: lpass_platform_pcmops_trigger: invalid 3 interface apq8016-lpass-cpu 7708000.audio-controller: ASoC: error at soc_component_trigger on 7708000.audio-controller: -22 Attempting to record analog audio results in: Unable to handle kernel NULL pointer dereference at virtual address 00000000000001e4 Internal error: Oops: 96000004 [#1] PREEMPT SMP CPU: 1 PID: 1568 Comm: arecord Not tainted 5.11.0-rc3 #20 Hardware name: Qualcomm Technologies, Inc.

Looking at the changes in "ASoC: qcom: Add support for lpass hdmi driver" there is a quite obvious mistake there. lpass.h now contains #include <dt-bindings/sound/sc7180-lpass.h> and then the SC7810 DAI IDs are hardcoded all over lpass-cpu.c and lpass-platform.c. But apq8016 and ipq806x have completely different DAI IDs so now MI2S_QUATERNARY (HDMI) is invalid and MI2S_TERTIARY (= LPASS_DP_RX in sc7180-lpass.h) is treated as HDMI port. Effectively LPASS is broken on all platforms except SC7810. I have a patch prepared to fix this (will send it tomorrow), but I wonder how you have tested this successfully on DB410c. :) Stephan

June reported this to me some time during Christmas. Look forward to review your patches! --srini > > Stephan >

However, in my patch I tried to avoid doing that for the following two reasons: - Changing dt-bindings after they are added is generally discouraged. but more importantly: - lpass-ipq806x.c does not seem to have PRIMARY, SECONDARY, ... but something completely different. I know nothing about that platform so I would not know how to handle it. I will post my patch and then you can decide. Thanks, Stephan
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.
