[PATCH v4 00/11] Fix broken usage of driver_override (and kfree of static memory)
by Krzysztof Kozlowski 15 Mar '22

15 Mar '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 since latest v3 ======================= 1. Wrap comments, extend comment in driver_set_override() about newline. 2. Minor commit msg fixes. 3. Add tags. Changes since latest v2 ======================= 1. Make all driver_override fields as "const char *", just like SPI and VDPA. (Mark) 2. Move "count" check to the new helper and add "count" argument. (Michael) 3. Fix typos in docs, patch subject. Extend doc. (Michael, Bjorn) 4. Compare pointers to reduce number of string readings in the helper. 5. Fix clk-imx return value. Changes since latest 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, merging and stable ================================ 1. All patches, including last three fixes, depend on the first patch introducing the helper. 2. Merging idea: everything via driver core (Greg KH?). 2. The last three commits - fixes - are probably not backportable directly, because of this dependency. I don't know how to express this dependency here, since stable-kernel-rules.rst mentions only commits as possible dependencies.

[PATCH] ASoC: sti: sti_uniperif: Remove driver
by Daniel Palmer 15 Mar '22

15 Mar '22

This driver seems to be in the "only good for attracting bot generated patches" phase of it's life. It doesn't seem like anyone actually tested the patches that have been applied in the last few years as uni_reader_irq_handler() had a dead lock added to it (it locks the stream, then calls snd_pcm_stop_xrun() which will also lock the stream). Seems best just to remove it. Signed-off-by: Daniel Palmer <daniel(a)0x0f.com> --- I've never used this driver, don't have the hardware etc. I just noticed that this looks broken when debugging my own driver that uses snd_pcm_stop_xrun() and was looking at other users to see if I was using it wrong and noticed this was the only place that locked the stream before calling snd_pcm_stop_xrun(). There are probably some other bits of the driver that should be removed but I didn't look that hard. TL;DR; This driver seems broken, seems like nobody uses it. Maybe it should be deleted? .../bindings/sound/st,sti-asoc-card.txt | 164 -- MAINTAINERS | 7 - sound/soc/sti/Kconfig | 12 - sound/soc/sti/Makefile | 5 - sound/soc/sti/sti_uniperif.c | 506 ------ sound/soc/sti/uniperif.h | 1416 ----------------- sound/soc/sti/uniperif_player.c | 1148 ------------- sound/soc/sti/uniperif_reader.c | 436 ----- 8 files changed, 3694 deletions(-) delete mode 100644 Documentation/devicetree/bindings/sound/st,sti-asoc-card.txt delete mode 100644 sound/soc/sti/Kconfig delete mode 100644 sound/soc/sti/Makefile delete mode 100644 sound/soc/sti/sti_uniperif.c delete mode 100644 sound/soc/sti/uniperif.h delete mode 100644 sound/soc/sti/uniperif_player.c delete mode 100644 sound/soc/sti/uniperif_reader.c diff --git a/Documentation/devicetree/bindings/sound/st,sti-asoc-card.txt b/Documentation/devicetree/bindings/sound/st,sti-asoc-card.txt deleted file mode 100644 index a6ffcdec6f6a..000000000000 --- a/Documentation/devicetree/bindings/sound/st,sti-asoc-card.txt +++ /dev/null @@ -1,164 +0,0 @@ -STMicroelectronics sti ASoC cards - -The sti ASoC Sound Card can be used, for all sti SoCs using internal sti-sas -codec or external codecs. - -sti sound drivers allows to expose sti SoC audio interface through the -generic ASoC simple card.

[PATCH v10 0/7] Add pin control support for lpass sc7280
by Srinivasa Rao Mandadapu 15 Mar '22

15 Mar '22

This patch series is to split lpass variant common pin control functions and SoC specific functions and to add lpass sc7280 pincontrol support. It also Adds dt-bindings for lpass sc7280 lpass lpi pincontrol. Changes Since V9: -- Add pinctrl groups macro to Kconfig. Changes Since V8: -- Remove redundant headers included in v8. Changes Since V7: -- Update optional clock voting with conditional check. -- Add const to lpi_pinctrl_variant_data structure. -- Update required headers and remove redundant. -- Change EXPORT_SYMBOL to EXPORT_SYMBOL_GPL -- Fix typo errors. Changes Since V6: -- Update conditional clock voting to optional clock voting. -- Update Kconfig depends on field with select. -- Fix typo errors. Changes Since V5: -- Create new patch by updating macro name to lpi specific. -- Create new patch by updating lpi pin group structure with core group_desc structure. -- Fix typo errors. -- Sort macros in the make file and configuration file. Changes Since V4: -- Update commit message and description of the chip specific extraction patch. -- Sort macros in kconfig and makefile. -- Update optional clock voting to conditional clock voting. -- Fix typo errors. -- Move to quicinc domain email id's. Changes Since V3: -- Update separate Kconfig fields for sm8250 and sc7280. -- Update module license and description. -- Move static variables to corresponding .c files from header file. Changes Since V2: -- Add new dt-bindings for sc7280 lpi driver. -- Make clock voting change as separate patch. -- Split existing pincontrol driver and make common functions as part of separate file. -- Rename lpass pincontrol lpi dt-bindings to sm8250 specific dt-bindings Changes Since V1: -- Make lpi pinctrl variant data structure as constant -- Add appropriate commit message -- Change signedoff by sequence. Srinivasa Rao Mandadapu (7): dt-bindings: pinctrl: qcom: Update lpass lpi file name to SoC specific dt-bindings: pinctrl: qcom: Add sc7280 lpass lpi pinctrl bindings pinctrl: qcom: Update macro name to LPI specific pinctrl: qcom: Update lpi pin group structure pinctrl: qcom: Extract chip specific LPASS LPI code pinctrl: qcom: Add SC7280 lpass pin configuration pinctrl: qcom: Update clock voting as optional Tested this on SM8250 MTP with WSA and WCD codecs.
