When CONFIG_TIMER_EARLY is selected and the timer driver implements timer_early_get_count() and timer_early_get_rate() this leads to an EAGAIN error one some configurations in...
common/board_f.c:initf_dm()
initf_dm() invokes dm_timer_init(), but this function returns with an EAGAIN error in, because the DM virtual root driver isn't initialized yet in...
drivers/timer/timer-class.c:dm_timer_init()
Moved error handling to...
lib/time.c
For details you can read the description in the patches.
Affected drivers: drivers/timer/andes_plmt_timer.c drivers/timer/sifive_clint_timer.c drivers/timer/riscv_timer.c
I don't know who maintains these base libraries and base functions, so I used the copyright holders. For the driver I added the required maintainers to CC.
