ASoC: codecs: lpass: fix the order or clks turn off during suspend

2023-04-13T15:02:36Z

[ Upstream commit a4a3203426f4b67535d6442ddc5dca8878a0678f ] The order in which clocks are stopped matters as some of the clock like NPL are derived from MCLK. Without this patch, Dragonboard RB5 DSP would crash with below error: qcom_q6v5_pas 17300000.remoteproc: fatal error received: ABT_dal.c:278:ABTimeout: AHB Bus hang is detected, Number of bus hang detected := 2 , addr0 = 0x3370000 , addr1 = 0x0!!! Turn off fsgen first, followed by npl and then finally mclk, which is exactly the opposite order of enable sequence.

ASoC: codecs: lpass: fix incorrect mclk rate

2023-03-10T08:28:39Z

[ Upstream commit e7621434378c40b62ef858c14ae6415fb6469a8e ] For some reason we ended up with incorrect mclk rate which should be 1920000 instead of 96000, So far we were getting lucky as the same clk is set to 192000 by wsa and va macro. This issue is discovered when there is no wsa macro active and only rx or tx path is tested. Fix this by setting correct rate.

ASoC: codecs: rx-macro: handle swr_reset correctly

Reset soundwire block on frame sync generation clock reset. Without this we are hitting read/write timeouts randomly during runtime pm. Along with this remove a swr_reset redundant flag.

ASoC: codecs: Fix an error handling path in (rx|tx|va)_macro_probe()

Merge tag 'asoc-v5.18' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2022-03-21T15:19:21Z

ASoC: Updates for v5.18 Quite a quiet release for ASoC, lots of work on drivers and platforms but nothing too groundbreaking but not much on the core itself: - Start of moving SoF to support multiple IPC mechanisms. - Use of NHLT ACPI table to reduce the amount of quirking required for Intel systems. - Some building blocks for use in forthcoming Intel AVS driver for legacy Intel DSP firmwares. - Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas RZ/V2L, Texas Instruments TAS585M

ASoC: codecs: Add power domains support in digital macro codecs

2022-02-28T13:30:37Z

Add support for enabling required power domains in digital macro codecs. macro and dcodec power domains are being requested as clocks by HLOS in ADSP based architectures and ADSP internally handling as powerdomains. In ADSP bypass case need to handle them as power domains explicitly.

ASoC: codecs: rx-macro: setup soundwire clks correctly

2022-02-25T13:51:07Z

For SoundWire Frame sync to be generated correctly we need both MCLK and MCLKx2 (npl). Without pm runtime enabled these two clocks will remain on, however after adding pm runtime support its possible that NPl clock could be turned off even when SoundWire controller is active. Fix this by enabling mclk and npl clk when SoundWire clks are enabled.
