From b34b9547cee41575a4fddf390f615570759dc999 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sun, 18 Feb 2024 18:41:37 +0100 Subject: clocksource/drivers/arm_global_timer: Fix maximum prescaler value The prescaler in the "Global Timer Control Register bit assignments" is documented to use bits [15:8], which means that the maximum prescaler register value is 0xff.
