[alsa-devel] [PATCH v2 0/12] Discover and probe dependencies
by Tomeu Vizoso 17 Jul '15

17 Jul '15

Hi, this is version 2 of a series that probes devices in dependency order so as to avoid deferred probes. While deferred probing is a powerful solution that makes sure that you eventually get a working system at the end of the boot, can make it very time consuming to find out why a device didn't probe and can also introduce big delays in when a device actually probes by sending it to the end of the deferred queue. So far I have only tested on a Tegra124 Chromebook. Thanks, Tomeu Changes in v2: - Instead of delaying all probes until late_initcall, only delay matches of platform devices that have a firmware node attached. - Allow bindings implementations register a function instead of using class callbacks, as not only subsystems implement firmware bindings. - Move strends to string.h - Document that consumers of backlight devices can use the 'backlight' property to hold a phandle to the backlight device. - Allocate the list of dependencies and pass it to the function that fills it.

[alsa-devel] [PATCH 1/4] ASoC: max9877: Make driver global regmap struct local
by Lars-Peter Clausen 16 Jul '15

16 Jul '15

Use a stack local variable to handle function local state rather than a global static variable. The later has a potential for race conditions if the probe function runs for two devices concurrently.

[alsa-devel] [PATCH 1/2] V4 regmap: Use reg_sequence for multi_reg_write / register_patch
by Nariman Poushin 16 Jul '15

16 Jul '15

Add support for writing sequences of registers / patches with specified delays (in microseconds). Logically separates the functionality using sequences of register writes from the functions that take register defaults, as adding a delay field on the reg_defaults can increase memory usage substantially. This also updates all the clients of multi_reg_write/register_patch.

[alsa-devel] [PATCH] ALSA: hda/realtek: Enable headphone amp on HP Folio 9480m
by Keith Packard 16 Jul '15

16 Jul '15

This laptop needs GPIO4 pulled high to enable the headphone amplifier. I modelled the patch on the existing GPIO4 code which pulls the line low for the same purpose.
