From 2d7fdbe23c990a843177e3bff9a093d2f5fa4e02 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Tue, 1 Jul 2014 11:33:16 +0200 Subject: [PATCH] ARM: at91: PIT: Use DIV_ROUND_CLOSEST to compute the cycles Until now, the pit_cycle computation was dividing the rate by HZ, rounding to the closest integer, but without using the appropriate macro.
