From bd829e9d1d7de3178d67d94043f43527213a63a0 Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Sun, 19 Dec 2010 19:10:28 -0300 Subject: [PATCH] [media] cx23885, cx25840: Provide IR Rx timeout event reports (Resending because Mauro reported losing some emails on IRC) Provide CX2388[578] IR receive timeout (RTO) reports in the final space raw event sent up the chain to the raw IR pulse decoders. This should allow the lirc decoder to actually measure the inter-transmission gap properly.
