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.
