Subject: [PATCH v2 0/3] Add inline encryption support
QCOM SDCC controller having Inline Crypto Engine support
Inline Crypto Engine do encryption/decryption on fly.
dm-inlinecrypt driver will be use to do encryption/decryption
with Inline Crypto Engine.
v2:
* Added new driver dm-inlinecrypt
* Dropped patch "md: dm-crypt: Set cc->iv_size to 4 bytes"
* squash patch "blk-crypto: Add additional algo modes for Inline"
encryption and patch "md: dm-crypt: Add additional algo modes for
inline encryption" to the dm-inlinecrypt driver.
* tested with dmsetup command as below
dmsetup create test-crypt --table '0 251904 inline-crypt aes128-xts-
plain a7f67ad520bd83b9725df6ebd76c3eeea7f67ad520bd83b9725df6ebd76c3eee

v1:
* This series of patches add additional modes for inline encryption
This series of patches depends on [1] Add inline encryption support for
dm-crypt
[1]: https://lore.kernel.org/all/b45d3b40-2587-04dc-9601-a9251dacf806@opensource.wdc.com/T/#ma01f08a941107217c93680fa25e96e8d406df790
* These patches tested on IPQ9574 with eMMC ICE for raw partition
encryption/decryption.
e.g:
dmsetup create test-crypt --table '0 251904 crypt aes128-xts-plain64
