From e34fe384cb7ecdd2643e8bf528e08e1c988abc8a Mon Sep 17 00:00:00 2001 From: Alexander Krutwig Date: Mon, 17 Oct 2016 14:15:34 +0200 Subject: termios: Add TERMIOS_IRQ_SERVER_DRIVEN Add a new interrupt server driven Termios mode (TERMIOS_IRQ_DRIVEN). This mode is identical to the interrupt driven mode except that a mutex is used for device level locking. The intended use case for this mode are device drivers that use the interrupt server, e.g. SPI or I2C connected devices.
