From f5c20eb32a93e936f7067bb0ce9efffc08d5bb59 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Tue, 8 Mar 2022 12:47:49 +0000 Subject: [PATCH] ARM: dts: bcm2711-rpi-ds: Disable the BCM2835 STC Although BCM2711 still includes the old BCM2835 system timer, the newer per-core local timers are preferred because they are more efficient to access and can generate core-specific interrupts. Make the usage clear by disabling the driver for the old STC.
