From 179e8078a768be8c18539bebe44dd94447142ccf Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 5 Aug 2010 21:21:17 -0400 Subject: [PATCH] drm/radeon/kms: rework combios i2c handling Handle asic specific table to hw mappings in combios_setup_i2c_bus() directly. This allows us to remove most of the combios quirks and clean up the i2c bus setup.
