[alsa-devel] [PATCH 2/3] ASoC: add SOC_DOUBLE_R_EXT_TLV control type

Joonyoung Shim jy0922.shim at samsung.com
Wed Jul 15 13:33:50 CEST 2009


This is a macro for double controls with special callback function and
TLV. The SOC_DOUBLE_R_EXT_TLV needs two registers and one shift for
double controls.
