From da7ee60b03bd66bb10974d7444aa444de6391312 Mon Sep 17 00:00:00 2001 From: Antti Seppälä Date: Tue, 31 Mar 2015 14:48:12 -0300 Subject: [media] rc: nuvoton-cir: Add support for writing wakeup samples via sysfs filter callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Nuvoton-cir utilizes the encoding capabilities of rc-core to convert scancodes from user space to pulse/space format understood by the underlying hardware. Converted samples are then written to the wakeup fifo along with other necessary configuration to enable wake up functionality.
