From 0f622e8cae379ee17e1ffe867336b74c5b16f958 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 29 Mar 2011 15:54:50 -0700 Subject: omap2+: Rename timer-gp.c into timer.c to combine timer init functions We can keep everything sys_timer and gptimer.c related code in timer.c as the code will be very minimal. Later on we can also remove timer-mpu.c, as it can be called from omap4_timer_init function. This allows us to get rid of confusing existing files. We currently have timer-gp.c, timer-mpu.c, and patches have been posted to add dmtimer.c. There's no need to have these multiple files, we can put everything into timer.c.
