From ea1e9c04fdffc16ceb9760c6ec5dd2916c19ad46 Mon Sep 17 00:00:00 2001 From: Philippe Reynes Date: Fri, 3 May 2019 19:43:08 +0200 Subject: dt: bcm63158: watchdog should use a 50Mhz clock The watchdog should use a clock at 50 Mhz, so instead of using the clock osc (200 Mhz), we define a reference clock at 50Mhz and use it for both watchdog.
