Subject: [PATCH 0/5] STM32 CRC update

This set of patches update the STM32 CRC driver.
It contains bug fix.

First fixes issue if we enable STM32 CRC32 hardware accelerator with
ext4 (with metadata-chksum enable) and other fs that use same direct
access to update crc32 API without previous init.
Second fixes some issues raise by the extra self-test.
Third fixes wrong hw usage if there is multiple IP on the SOC.
Forth fixes "sleep while atomic" in tcrypt test, and some other places
(ext4)
Last fixes concurrent accesses. As state is saved in the hardware cell
and not in stack as other CRC32 drivers, we need to create atomic
section to protect concurrent CRC32 calculus.

This patch series applies to cryptodev/master.

Nicolas Toromanoff (5):
  crypto: stm32/crc: fix ext4 chksum BUG_ON()
  crypto: stm32/crc: fix run-time self test issue.
  crypto: stm32/crc: fix multi-instance
  crypto: stm32/crc: don't sleep in runtime pm
  crypto: stm32/crc: protect from concurrent accesses
