- Subject: [PATCH] dts: bcm2711: Don't mark timer regs unconfigured
- The DT property arm,cpu-registers-not-fw-configured tells the kernel
- that the ARM architectural timer has not been configured by the
- firmware. This prevents the use of a vDSO - a faster alternative to a
- syscall for some common kernel operations.
- However, on Pi 4 the firmware does configure the timer, so this property
- is unnecessary. Delete it.
- Also remove it from the bcm2712.dtsi where it should never have been,
- since it is only relevant to 32-bit ARM kernels.
