From 2603fe21b764eb7412598c8c6cd6199fb8b1d9c5 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Mon, 3 Nov 2014 21:35:48 +0100 Subject: [PATCH] ALSA: es18xx: Add GPO controls Add GPO0 and GPO1 (General Purpose Outputs) controls to mixer. These can be used on some cards to control amplifier mute (seen in ES1868 datasheet) or additional onboard chips such as QX2130 QXpander processor. These GPOs are present on ES1868, ES1869, ES1887 and ES1888 chips. Tested on ES1868 with QX2130. Signed-off-by: Ondrej Zary Signed-off-by: Takashi Iwai --- Reading git-format-patch failed
