[PATCH 1/9] ASoC: amd: vg: fix for pm resume callback sequence
by Vijendar Mukunda 25 Feb '22

25 Feb '22

The previous condition is used to cross check only the active stream status for I2S HS instance playback and capture use cases. Modified logic to invoke sequence for two i2s controller instances.

[PATCH v2 00/16] ASoC: codecs: add pm runtime support for Qualcomm codecs
by Srinivas Kandagatla 25 Feb '22

25 Feb '22

This patchset adds support for runtime pm on tx/rx/wsa/wcd lpass macro, wsa881x and wcd938x codecs that are wired up on SoundWire bus. During pm testing it was also found that soundwire clks enabled by lpass macros are not enabling all the required clocks correctly, so last 3 patches corrects them. Tested this on SM8250 MTP along SoundWire In band Headset Button wakeup interrupts. Changes since v1: - move to handing clks individually from clk bluk apis - tidy up the clk provider side code by using devm variants - added error handling.

[PATCH] sound/soc/amd: Use platform_get_irq_byname() to get the interrupt
by Meng Tang 25 Feb '22

25 Feb '22

platform_get_resource_byname(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq_byname().

[PATCH v2 00/11] Fix broken usage of driver_override (and kfree of static memory)
by Krzysztof Kozlowski 25 Feb '22

25 Feb '22

Hi, This is a continuation of my old patchset from 2019. [1] Back then, few drivers set driver_override wrong. I fixed Exynos in a different way after discussions. QCOM NGD was not fixed and a new user appeared - IMX SCU. It seems "char *" in driver_override looks too consty, so we tend to make a mistake of storing there string literals. Changes of latest since v1 (not the old 2019 solution): ======================================================= https://lore.kernel.org/all/708eabb1-7b35-d525-d4c3-451d4a3de84f@rasmusvill… 1. Add helper for setting driver_override. 2. Use the helper. Dependencies (and stable): ========================== 1. All patches, including last three fixes, depend on first patch introducing the helper. 2. The last three commits - fixes - are probably not backportable directly, because of this dependency. I don't know how to express it here, since stable-kernel-rules.rst mentions only commits as possible dependencies.
