[alsa-devel] [PATCH v2 3/3] ASoC: twl6040: Add jack support for headset and handset
by Olaya, Margarita 07 Dec '10

07 Dec '10

From: Jorge Eduardo Candelaria <jorge.candelaria(a)ti.com> This patch adds support for reporting twl6040 headset and handset jack events. The machine driver retrieves and report the status through twl6040_hs_jack_detect in case of the early interrupt.
