[alsa-devel] [PATCH 1/6] ASoC: Intel: Add support for Haswell/Broadwell DSP
by Liam Girdwood 24 Feb '14

24 Feb '14

Add support for low level differentiation functions for Haswell and Broadwell SST DSPs. This includes suppoprt for DSP boot and reset, DSP firmware module parsing and DSP memory block map initialisation.

[alsa-devel] [PATCH] ALSA: hda - Add a fixup for HP Folio 13 mute LED

24 Feb '14

HP Folio 13 may have a broken BIOS that doesn't set up the mute LED GPIO properly, and the driver guesses it wrongly, too. Add a new fixup entry for setting the GPIO pin statically for this laptop.

[alsa-devel] [PATCH] ALSA: hda - Avoid codec D3 for keeping mute LED up on Lenovo Yxx0
by Takashi Iwai 24 Feb '14

24 Feb '14

The GPIO line used for the mute LED control on Lenovo Yxx0 laptops is cleared unexpectedly when the codec goes to D3, typically by power-saving. For avoiding it, add a power filter in the fixup.

[alsa-devel] [PATCH v2 1/2] ALSA: Use priority list for managing device list
by Takashi Iwai 24 Feb '14

24 Feb '14

Basically, the device type specifies the priority of the device to be registered / freed, too. However, the priority value isn't well utilized but only it's checked as a group. This results in inconsistent register and free order (where each of them should be in reversed direction). This patch simplifies the device list management code by simply inserting a list entry at creation time in an incremental order for the priority value. Since we can just follow the link for register, disconnect and free calls, we don't have to specify the group; so the whole enum definitions are also simplified as well. The visible change to outside is that the priorities of some object types are revisited. For example, now the SNDRV_DEV_LOWLEVEL object is registered before others (control, PCM, etc) and, in return, released after others. Similarly, SNDRV_DEV_CODEC is in a lower priority than SNDRV_DEV_BUS for ensuring the dependency. Also, the unused SNDRV_DEV_TOPLEVEL, SNDRV_DEV_LOWLEVEL_PRE and SNDRV_DEV_LOWLEVEL_NORMAL are removed as a cleanup.
