From 934a50bd089789d1ed74f0bef4988a97bd590afe Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 7 Feb 2013 16:31:57 +0100 Subject: atmel_lcdfb: move lcdcon2 register access to compute_hozval Pass atmel_lcd_info structure to compute_hozval and only do the register access on SOCs that actually use it. This will also simplify the removal of the cpu_is macros.
