From 8a398d757dd0f56c8ac621104b198ff66eef7a7a Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Thu, 21 Mar 2013 14:03:14 +0000 Subject: MIPS: BCM63XX: remove duplicate spi register definitions BCM6338 and BCM6348, and BCM6358 and everything after that share the same register layout. To not have to redefine them for each new chip and keep the code size small, only use the definitions for the first chip with the certain layout.
