[alsa-devel] [PATCH v2 0/6] DT: Fix spelling of standard properties
by Geert Uytterhoeven 24 Oct '16

24 Oct '16

Hi all, This patch series fixes misspellings of various standard DT properties in DT binding documentation, DTS files, and error messages. While most of these are harmless, some of them may cause hard-to-debug failures. Changes compared to v2: - Dropped patches that have been applied already, - Add Rob Herring's Acked-by, - Split off "[PATCH v2 4/6] ASoC: davinci-mcbsp: DT fix s/interrupts-names/interrupt-names/" from the unrelated "[PATCH 06/14] dmaengine: bcm2835: DT spelling s/interrupts-names/interrupt-names/", - Add new patch "[PATCH v2 3/6] arm64: dts: lg1313: DT fix s/#interrupts-cells/#interrupt-cells/". Please apply where appropriate. Thanks! P.S. I used the following to detect misspellings: words="(address|clock|cooling|dma|gpio|index|interrupt|mbox|msi|nvmem|phy|phys|power-domain|pwm|reset|size|sleep|sound-dai|thermal-sensor)" git grep -Ew "${words}s-names" git grep -E "[^-]\<${words}-name\>[^-]" git grep -Ew "#${words}s-cells" # false positive phys-cells git grep -E "#${words}-cell\>[^-]" git grep -w adress-cells git grep -Ew "interrupts-(map|parent)" Geert Uytterhoeven (6): ARM: dts: STiH407: DT fix s/interrupts-names/interrupt-names/ arm64: dts: lg1312: DT fix s/#interrupts-cells/#interrupt-cells/ arm64: dts: lg1313: DT fix s/#interrupts-cells/#interrupt-cells/ ASoC: davinci-mcbsp: DT fix s/interrupts-names/interrupt-names/ dt: booting-without-of: DT fix s/#interrupt-cell/#interrupt-cells/ powerpc: dts: acadia: DT fix s/#interrupts-parent/#interrupt-parent/ Documentation/devicetree/bindings/sound/davinci-mcbsp.txt | 2 +- Documentation/devicetree/booting-without-of.txt | 2 +- arch/arm/boot/dts/stih407-pinctrl.dtsi | 2 +- arch/arm64/boot/dts/lg/lg1312.dtsi | 2 +- arch/arm64/boot/dts/lg/lg1313.dtsi | 2 +- arch/powerpc/boot/dts/acadia.dts | 2 +- 6 files changed, 6 insertions(+), 6 deletions(-) -- 1.9.1 Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert(a)linux-m68k.org In personal conversations with technical people, I call myself a hacker.

[alsa-devel] [PATCH 0/7] ALSA: Add rewinds disabled, delays, max_inflight_bytes
by Subhransu S. Prusty 21 Oct '16

21 Oct '16

Set of patches to fix issues with delays, hw_ptr fuzziness [1] and increased buffering w/ DSPs 1. Rewinds can be disabled when data written in ring buffer will never be validated. This allow for new HDaudio SPIB DMA functionality(allow fetch up to the application pointer, no rewind supported) 2. Report max in-flight bytes to avoid problems with stale data (like late wake-ups, rewinds) 3. add new estimate for USB startup delay.
