New subject: [alsa-devel] [PATCH 1/5] ASoC: Push workqueue data into snd_soc_card

ASoC v2 does not use the struct snd_soc_device at runtime, using struct snd_soc_card as the root of the card. Begin removing data from snd_soc_device by pushing the workqueue data into snd_soc_card, using a backpointer to the snd_soc_device to keep things going for the time being.

New subject: [alsa-devel] [PATCH] leds: Add WM8350 LED driver

The voltage and current regulators on the WM8350 AudioPlus PMIC can be used in concert to provide a power efficient LED driver. This driver implements support for this within the standard LED class.

Platform initialisation code should configure the LED hardware in the init callback provided by the WM8350 core driver. The callback should use wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and wm8350_dcdc_set_slot() to configure the operating parameters of the regulators for their hardware and then then use wm8350_register_led() to instantiate the LED driver.

This driver was originally written by Liam Girdwood, though it has been extensively modified since then.

New subject: [alsa-devel] [PATCH 3/5] ASoC: TWL4030: Add input selection and gain controls

From: Grazvydas Ignotas notasas@gmail.com

The TWL4030 codec device has two ADCs. Both of them can have several inputs routed to them, but TRM says that only one source can be selected for every ADC, even though every source has a dedicated bit in the registers.

This patch adds input source controls. It modifies default register values to have no inputs selected and ADCs disabled. When some input is selected, control handlers enable apropriate input amplifier and ADC. If a microphone is selected, bias power is automatically enabled. When some input is deselected, unused chip parts are disabled.

Microphone and line input recording tested on OMAP3 pandora board.

The voltage and current regulators on the WM8350 AudioPlus PMIC can be used in concert to provide a power efficient LED driver. This driver implements support for this within the standard LED class.

Gah, sorry - this was lying about in the directory when I did git send-email. It's not in the branch advertised.
