This is a copy of rand32_timer.c that uses z_do_read_cpu_timestamp32() instead of k_cycle_get_32(), with some logic to ensure different values when called in rapid succession missing. Like the other driver, its reported values are not random, it's a testing generator only. This appears to have no advantages over rand32_timer.c, just remove it. In QEMU emulation, the reported TSC values tend to have the lowest five bits zeroed. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
