From b3d12e9bca1b23a537d77af2ae019cddc59f2031 Mon Sep 17 00:00:00 2001 From: Nikita Kiryanov Date: Tue, 3 Feb 2015 13:32:22 +0200 Subject: lcd: atmel: move atmel-specific fb_put_word to atmel_lcdfb Reduce the amount of platform-specific code in common/lcd.c by moving Atmel implementation of fb_put_word() to atmel_lcdfb.c. Since we must also have a default implementation for everybody else, make the remainder of the code into a weak function.
