From d5e5265315770bda46c50ecaa64e2b9790f2064c Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 8 Nov 2005 21:37:32 -0800 Subject: [PATCH] v4l: 784: several improvement on i2c ir handling for em2820 - Several Improvement on I2C IR handling for em2820: - moved Pinnacle IR table (ir_codes_em2820) to em2820-input.c - IR struct renamed and moved to a header file. - New file to handle em2820-specific IR. - Some cleanups. - attach now detects I2C IR and calls em2820-specific IR code - IR compat code moved to compat.h - New header with struct IR_i2c there, to allow it to be used by board-specific input handlers. - Some improvements at em28xx board detection: - Board detection message improved to show interface and class. - Now it doesn't touch audio interfaces.
