From 9c661c498eaa200304a770c469ec180a2a6c0485 Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Wed, 21 Mar 2012 19:40:07 +0100 Subject: [PATCH] srd: Drop ebr30a_i2c_demux in favor of i2cdemux. The i2cdemux protocol decoder is the more generic version of the obsolete ebr30a_i2c_demux decoder, and should be able (now or later) to do everything that ebr30a_i2c_demux can do. --- configure.ac | 1 - decoders/Makefile.am | 1 - decoders/ebr30a_i2c_demux/Makefile.am | 26 ----- decoders/ebr30a_i2c_demux/__init__.py | 36 ------- decoders/ebr30a_i2c_demux/ebr30a_i2c_demux.py | 96 ------------------- 5 files changed, 160 deletions(-) delete mode 100644 decoders/ebr30a_i2c_demux/Makefile.am delete mode 100644 decoders/ebr30a_i2c_demux/__init__.py delete mode 100644 decoders/ebr30a_i2c_demux/ebr30a_i2c_demux.py diff --git a/configure.ac b/configure.ac index 452a707..8b783e6 100644 --- a/configure.ac +++ b/configure.ac @@ -153,7 +153,6 @@ AC_CONFIG_FILES([Makefile libsigrokdecode.pc decoders/Makefile decoders/dcf77/Makefile - decoders/ebr30a_i2c_demux/Makefile decoders/edid/Makefile decoders/i2c/Makefile decoders/i2cdemux/Makefile diff --git a/decoders/Makefile.am b/decoders/Makefile.am index c78e515..44b9a53 100644 --- a/decoders/Makefile.am +++ b/decoders/Makefile.am @@ -21,7 +21,6 @@ # Please keep this list in alphabetical order.
