[alsa-devel] [PATCH 7/8] ASoC: pxa: tosa: Convert to table based DAPM and control setup

[Lars-Peter Clausen]

Use table based setup to register the controls and DAPM widgets and routes. This
on one hand makes the code a bit shorter and cleaner and on the other hand the
board level DAPM elements get registered in the card's DAPM context rather than
in the CODEC's DAPM context.
