From 69ad78208ecf4c392f3d323ed050423847c24104 Mon Sep 17 00:00:00 2001 From: Sjur Braendeland Date: Thu, 17 Jun 2010 06:55:41 +0000 Subject: [PATCH] caif: Add debug connection type for CAIF. Added new CAIF protocol type CAIFPROTO_DEBUG for accessing CAIF debug on the ST Ericsson modems. There are two debug servers on the modem, one for radio related debug (CAIF_RADIO_DEBUG_SERVICE) and the other for communication/application related debug (CAIF_COM_DEBUG_SERVICE). The debug connection can contain trace debug printouts or interactive debug used for debugging and test. Debug connections can be of type STREAM or SEQPACKET.
