From 0ef99f8202c5078a72c05af76bfaed2ea4daab19 Mon Sep 17 00:00:00 2001 From: Claudiu Beznea Date: Mon, 11 Oct 2021 14:27:14 +0300 Subject: clk: at91: clk-master: fix prescaler logic When prescaler value read from register is MASTER_PRES_MAX it means that the input clock will be divided by 3. Fix the code to reflect this.
