From 49cf3f29a1ef2e59f1be823e376c1fbac586eb8d Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 1 Jun 2011 19:05:07 +0100 Subject: i8253: Consolidate definitions of PIT_LATCH x86 defines PIT_LATCH as LATCH which in is defined as ((CLOCK_TICK_RATE + HZ/2) / HZ) and again defines CLOCK_TICK_RATE as PIT_TICK_RATE. MIPS defines PIT_LATCH as LATCH which in is defined as ((CLOCK_TICK_RATE + HZ/2) / HZ) and again defines CLOCK_TICK_RATE as 1193182. ARM defines PITCH_LATCH as ((PIT_TICK_RATE + HZ / 2) / HZ) - and that's the sanest thing and equivalent to above definitions so use that as the new definition in .
