+Subject: [PATCH] arm64: dts: broadcom: bcm4908: use proper TWD binding
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Block at <ff800400 0x4c> is a TWD that contains timers, watchdog and
+reset. Actual timers happen to be at block beginning but they only span
+across the first 0x28 registers. It means the old block description was
+incorrect (size 0x3c).
+
+Drop timers binding for now and use documented TWD binding. Timers
+should be properly documented and defined as TWD subnode.
+
+Fixes: 2961f69f151c ("arm64: dts: broadcom: add BCM4908 and Asus GT-AC5300 early DTS files")
