[PATCH v2 0/6] hwrng: imx-rngc - use polling instead of interrupt

From: Martin Kaiser
Date: Thu Aug 24 2023 - 15:25:11 EST


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
