From baaa7dd7061521509792ca158508b2c4554a7184 Mon Sep 17 00:00:00 2001 From: Nikita Kiryanov Date: Tue, 3 Feb 2015 13:32:20 +0200 Subject: lcd: move platform-specific structs to their own headers common/lcd code is full of platform-specific code and definitions, which ideally should reside with the respective driver code. Take a step towards that goal by moving platform-specific structs from lcd.h to their own header files. The structs for the generic case (the #else for all the platform-specific cases) is retained in lcd.h as the default case.
