[PATCH 0/2] Do not handle MCLK device clock in simple-card-utils
by Sameer Pujar 16 Mar '21

16 Mar '21

With commit 1e30f642cf29 ("ASoC: simple-card-utils: Fix device module clock") simple-card-utils can control MCLK clock for rate updates or enable/disable. But this is breaking some platforms where it is expected that codec drivers would actually handle the MCLK clock. One such example is following platform. - "arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var3-ads2.dts" In above case codec, wm8904, is using internal PLL and configures sysclk based on fixed MCLK input. In such cases it is expected that, required PLL output or sysclk, is just passed via set_sysclk() callback and card driver need not actually update MCLK rate. Instead, codec can take ownership of this clock and do the necessary configuration. So the original commit is reverted and codec driver for rt5659 is updated to fix my board which has this codec.

[PATCH] ASoC: wm8962: Relax bit clock divider searching
by Shengjiu Wang 16 Mar '21

16 Mar '21

With S20_3LE format case, the sysclk = rate * 384, the bclk = rate * 20 * 2, there is no proper bclk divider for 384 / 40, because current condition needs exact match. So driver fails to configure the clocking: wm8962 3-001a: Unsupported BCLK ratio 9 Fix this by relaxing bitclk divider searching, so that when no exact value can be derived from sysclk pick the closest value greater than expected bitclk.

[PATCH v0] ASoC: rsnd: core: Check convert rate in rsnd_hw_params
by mdurnev＠gmail.com 16 Mar '21

16 Mar '21

From: Mikhail Durnev <mikhail_durnev(a)mentor.com> snd_pcm_hw_params_set_rate_near can return incorrect sample rate in some cases, e.g. when the backend output rate is set to some value higher than 48000 Hz and the input rate is 8000 Hz. So passing the value returned by snd_pcm_hw_params_set_rate_near to snd_pcm_hw_params will result in "FSO/FSI ratio error" and playing no audio at all while the userland is not properly notified about the issue. If SRC is unable to convert the requested sample rate to the sample rate the backend is using, then the requested sample rate should be adjusted in rsnd_hw_params. The userland will be notified about that change in the returned hw_params structure.

[PATCH v2 0/7] ASoC: codecs: add wcd938x support
by Srinivas Kandagatla 16 Mar '21

16 Mar '21

This patchset adds support for Qualcomm WCD938X codec. Qualcomm WCD9380/WCD9385 Codec is a standalone Hi-Fi audio codec IC connected over SoundWire. This device has two SoundWire devices, RX and TX respectively supporting 4 x ADCs, ClassH, Ear, Aux PA, 2xHPH, 7 x TX diff inputs, 8 DMICs and MBHC. Even though this device has two SoundWire devices, only tx device has access to main codec Control/Status Registers! This patchset along with other SoundWire patches on the list have been tested on SM8250 MTP device. Am planning to send support for MBHC once this driver gets accepted! Thanks, srini Many thanks for reviewing v1. Changes since v1: - updated PA gain to a proper TLV control - move various if else checks to switch case. - return error on check failure rather than fallback to default - cleaned up micbias pull up control - fixed all the gain tlvs correctly - update dt-bindings to use microvolt for button thresholds - removed unnecessary debug at various places.
