From 8f7ba051d2abb3d3bde9b95e47246c60b704d2b4 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 22 Feb 2007 16:07:21 +0100 Subject: [ALSA] mpu401 - Add MPU401_INFO_UART_ONLY bitflag Added MPU401_INFO_UART_ONLY bitflag to avoid issueing UART_ENTER command at opening streams. Some devices support only UART mode and give errors to UART_ENTER. A new module option, uart_enter, is added to snd-mpu401 driver. For UART-only devices, set uart_enter=0.
