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.
|
