From 38a1981ce31dc4c527cbc0137f638543261b471a Mon Sep 17 00:00:00 2001 From: Sricharan R Date: Wed, 18 Sep 2013 16:50:11 +0530 Subject: [PATCH] ARM: OMAP2+: DRA7: realtime_counter: Add ratio registers for 20MHZ sys-clk frequency The real time counter also called master counter, is a free-running counter. It produces the count used by the CPU local timer peripherals in the MPU cluster. The timer counts at a rate of 6.144 MHz. The ratio registers are missing for a sys-clk of 20MHZ which is used by DRA7 socs. So because of this, the counter was getting wrongly programmed for a sys-clk of 38.4Mhz(default). So adding the ratio registers for 20MHZ sys-clk.
