From 91ed53491f4fa31879e0965a7e920dc10f78996c Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 23 May 2017 11:08:04 +0200 Subject: [PATCH] i2c: rename core source file to allow refactorization The I2C core became quite huge and its monolithic structure makes maintenance hard. So, prepare to break out some functionality into separate files by renaming the source file. Note that we keep the resulting object name constant to avoid regressions.
