Subject: [PATCH v3 0/2] Use GCR.U timer device as clocksource

HTEC Public

This series adds bindings for the GCR.U timer device and corresponding
driver support. Accessing the memory mapped mtime register in the GCR.U
region should be faster than trapping to M mode each time the timer
needs to be read.


Aleksa Paunovic (2):
  dt-bindings: timer: mti,gcru
  Allow for riscv-clock to pick up mmio address.
