Subject: [PATCH V4 0/4] Add Xilinx's ZynqMP AES-GCM driver support

This patch set adds support for
- dt-binding docs for Xilinx ZynqMP AES driver
- Adds device tree node for ZynqMP AES driver
- Adds communication layer support for aes in zynqmp.c
- Adds Xilinx ZynqMP driver for AES Algorithm

V4 Changes :
- Addressed review comments.

V3 Changes :
- Added software fallback in cases where HW doesnt have  the capability to handle the request.
- Removed use of global variable for storing the driver data.
- Enabled CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y and executed all  the kernel selftests. Also covered tests with tcrypt module.

V2 Changes :
- Converted RFC PATCH to PATCH
- Removed ALG_SET_KEY_TYPE that was added to support keytype
  attribute. Taken using setkey interface.
- Removed deprecated BLKCIPHER in Kconfig
- Erased Key/IV from the buffer.
- Renamed zynqmp-aes driver to zynqmp-aes-gcm.
- Addressed few other review comments


Kalyani Akula (4):
  dt-bindings: crypto: Add bindings for ZynqMP AES driver
  ARM64: zynqmp: Add Xilinix AES node.
  firmware: xilinx: Add ZynqMP aes API for AES functionality
  crypto: Add Xilinx AES driver
