[alsa-devel] [PATCH] ASoC: Use the correct DAPM context when cleaning up final widget set
by Mark Brown 09 Mar '11

09 Mar '11

Now we've got multi-component we need to make sure that the DAPM context (and hence register I/O context) we use to apply the pending updates at the end of a DAPM sequence is the one we were processing rather than the one that was used to initate the state change.

[alsa-devel] [PATCH 1/2] ASoC: Provide CODEC clocking operations and API calls
by Mark Brown 08 Mar '11

08 Mar '11

When multi component systems use DAIless amplifiers which require clocking configuration it is at best hard to use the current clocking API as this requires a DAI even though the device may not even have one. Address this by adding set_sysclk() and set_pll() operations and APIs for CODECs. In order to avoid issues with devices which could be used either with or without DAIs make the DAI variants call through to their CODEC counterparts if there is no DAI specific operation. Converting over entirely would create problems for multi-DAI devices which offer per-DAI clocking setup.
