Use polling and wait actively for the self test and the initial seeding of the rngc to complete. This is much simpler than using an interrupt and a completion. v2: - set reasonable timeouts - separate commit for the removal of interrupt handling - readl_poll_timeout does not wait in the foreground Martin Kaiser (6): hwrng: imx-rngc - reasonable timeout for selftest hwrng: imx-rngc - reasonable timeout for initial seed hwrng: imx-rngc - use polling to detect end of self test hwrng: imx-rngc - read status register for error checks hwrng: imx-rngc - use polling for initial seed hwrng: imx-rngc - remove interrupt handler drivers/char/hw_random/imx-rngc.c | 100 ++++++------------------------ 1 file changed, 18 insertions(+), 82 deletions(-) -- 2.39.2
