From 4d133982271fd063779174d1695e14c7821c6da6 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Thu, 21 Jun 2012 16:04:18 -0400 Subject: I2C: Deprecate I2C_REMAP flag. This is ad-hoc and nonportable. If you really want I2C mapped elsewhere, then mess with the I2C device fields and call afio_remap() yourself. (This is also cleaner for F2).
