2025-03-17ASoC: tegra210: Convert to RUNTIME_PM_OPS() & coTakashi Iwai
Use the newer RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros instead of SET_RUNTIME_PM_OPS() and SET_SYSTEM_SLEEP_PM_OPS() together with pm_ptr(), which allows us dropping ugly __maybe_unused attributes. This optimizes slightly when CONFIG_PM is disabled, too.

2024-09-14Merge tag 'asoc-v6.12' of ↵Takashi Iwai
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v6.12 This is a very large set of changes, almost all in drivers rather than the core. Even with the addition of several quite large drivers the overall diffstat is negative thanks to the removal of some old Intel board support which has been obsoleted by the AVS driver, helped a bit by some factoring out into helpers (especially around the Soundwire machine drivers for x86). Highlights include: - More simplifications and cleanups throughout the subsystem from Morimoto-san. - Extensive cleanups and refactoring of the Soundwire drivers to make better use of helpers. - Removal of Intel machine support obsoleted by the AVS driver. - Lots of DT schema conversions. - Machine support for many AMD and Intel x86 platforms. - Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320 SoundWire and rev C, and Texas Instruments TAS2563
2024-09-09ASoC: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all drivers below sound/soc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2024-08-23ASoC: tegra: Fix CBB error during probe()Mohan Kumar
When Tegra audio drivers are built as part of the kernel image, TIMEOUT_ERR is observed from cbb-fabric. Following is seen on Jetson AGX Orin during boot: [ 8.012482] ************************************** [ 8.017423] CPU:0, Error:cbb-fabric, Errmon:2 [ 8.021922] Error Code : TIMEOUT_ERR [ 8.025966] Overflow : Multiple TIMEOUT_ERR [ 8.030644] [ 8.032175] Error Code : TIMEOUT_ERR [ 8.036217] MASTER_ID : CCPLEX [ 8.039722] Address : 0x290a0a8 [ 8.043318] Cache : 0x1 -- Bufferable [ 8.047630] Protection : 0x2 -- Unprivileged, Non-Secure, Data Access [ 8.054628] Access_Type : Write [ 8.106130] WARNING: CPU: 0 PID: 124 at drivers/soc/tegra/cbb/tegra234-cbb.c:604 tegra234_cbb_isr+0x134/0x178 [ 8.240602] Call trace: [ 8.243126] tegra234_cbb_isr+0x134/0x178 [ 8.247261] __handle_irq_event_percpu+0x60/0x238 [ 8.252132] handle_irq_event+0x54/0xb8 These errors happen when MVC device, which is a child of AHUB device, tries to access its device registers. This happens as part of call tegra210_mvc_reset_vol_settings() in MVC device probe(). The root cause of this problem is, the child MVC device gets probed before the AHUB clock gets enabled. The AHUB clock is enabled in runtime PM resume of parent AHUB device and due to the wrong sequence of pm_runtime_enable() in AHUB driver, runtime PM resume doesn't happen for AHUB device when MVC makes register access. Fix this by calling pm_runtime_enable() for parent AHUB device before of_platform_populate() in AHUB driver. This ensures that clock becomes available when MVC makes register access.

2023-03-20ASoC: tegra: tegra210_ahub: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2020-07-20ASoC: tegra: Add Tegra210 based AHUB driverSameer Pujar
The Audio Hub (AHUB) comprises a collection of hardware accelerators for audio pre/post-processing and a programmable full crossbar (XBAR) for routing audio data across these accelerators in time and in parallel. AHUB supports multiple interfaces to I2S, DSPK, DMIC etc., XBAR is a switch used to configure or modify audio routing between HW accelerators present inside AHUB. This patch registers AHUB component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes AHUB interfaces, which can be used to connect different components in the ASoC layer. Currently the driver takes care of XBAR programming to allow audio data flow through various clients of the AHUB. Makefile and Kconfig support is added to allow to build the driver. The AHUB component can be enabled in the DT via below compatible bindings. - "nvidia,tegra210-ahub" for Tegra210 - "nvidia,tegra186-ahub" for Tegra186 and Tegra194 Signed-off-by: Sameer Pujar <spujar@nvidia.com> Link: https://lore.kernel.org/r/1595134890-16470-6-git-send-email-spujar@nvidia.com Signed-off-by: Mark Brown <broonie@kernel.org>
