[alsa-devel] [PATCH V3 0/3] Add audio support on smdk5420
by Padmavathi Venna 09 Aug '13

09 Aug '13

Samsung has different versions of I2S introduced in different platforms. Each version has some new support added for multichannel, secondary fifo, s/w reset control, internal mux for rclk src clk and tdm support. Each newly added change has a quirk. So this patch adds all the required quirks as driver data and based on compatible string from dtsi fetches the quirks. This also adds i2s support on exynos5420. Changes since V2: - Seperated out driver side changes and dts changes in two patch sets. - Replaced samsung,s3c6410-i2s-v4 with samsung,s3c6410-i2s-multi for more clarity as suggested by Tomasz Figa. Changes since V1: - Pass quirks as driver data and fetch the quirks based on compatible string from dtsi file as suggested by Tomasz Figa and Mark Brown - Make the I2S driver more flexible with respect to register access as suggested by Tomasz Figa and Mark Brown - Add 5420 support in the driver. - Modify the dtsi files with the corresponding compatible strings and removed the i2s quirks from 5250 dtsi file. - Updated the i2s Documentation with relevent changes and i2s versioning info. - Add i2s nodes on exynos5420.dtsi - Enable sound support on smdk5420 This patch set is made based on Mark Brown for-next branch on sound.git.

[alsa-devel] Found a typo
by Torino 09 Aug '13

09 Aug '13

Dear Alsa developers, within Saucy (13.10), "alsa-utils", string nr. 124 it says "Channel %d doesn't match with hw_parmas" whereas in other strings like nr. 84 or 126 it says "hw_params". I hope it was correct informing you via this mailing list. Best Regads, Torino (from the German Übersetzer-Team)

[alsa-devel] [PATCH] ALSA: usb-audio: do not trust too-big wMaxPacketSize values
by Clemens Ladisch 08 Aug '13

08 Aug '13

The driver used to assume that the streaming endpoint's wMaxPacketSize value would be an indication of how much data the endpoint expects or sends, and compute the number of packets per URB using this value. However, the Focusrite Scarlett 2i4 declares a value of 1024 bytes, while only about 88 or 44 bytes are be actually used. This discrepancy would result in URBs with far too few packets, which would not work correctly on the EHCI driver. To get correct URBs, use wMaxPacketSize only as an upper limit on the packet size.

[alsa-devel] [PATCH v4 0/1] ASoc: kirkwood: extend the kirkwood audio subsystem for DT usage
by Jean-Francois Moine 08 Aug '13

08 Aug '13

This patch series adds DT support to the kirkwood/mvebu audio subsystem. History v4 - change the DT name to "mrvl,mvebu-audio" - remove previous patches 1..3 which have been applied by Russell King v3 - change the DT name from "kirkwood-i2s" to "mvebu-pcm-audio" - apply to linux-next - let NULL as the internal i2s clock for compatibility - change i2s external clock name to "extclk" instead of "external" - cancel previous patch 1/4. Russell's patch should be applied instead. v2 - fix compilation errors -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
