X-Git-Tag: v2.6.23-rc1~215^2~61
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=92a22beb756c53985e8ba98d39f2c8fc834557a4;p=karo-tx-linux.git

[ALSA] hda: add eapd support to additional idt codecs

Added support for EAPD on the 927x, and 9227-8 IDT HDA codecs.
Enabling EAPD powers the internal speaker amp otherwise there is no
sound on systems with an internal amp.
