[PATCH v2 01/14] crypto: sun4i-ss - simplify optional reset handling

As of commit bb475230b8e5 ("reset: make optional functions really optional"), the reset framework API calls use NULL pointers to describe optional, non-present reset controls. This allows to return errors from devm_reset_control_get_optional and to call reset_control_(de)assert unconditionally. S

[PATCH 1/4] crypto: powerpc - Factor out the core CRC vpmsum algorithm

The core nuts and bolts of the crc32c vpmsum algorithm will also work for a number of other CRC algorithms with different polynomials. Factor out the function into a new asm file. To handle multiple users of the function, a user simply provides constants, defines the name of their CRC function, an

[PATCH 2/4] crypto: powerpc - Re-enable non-REFLECTed CRCs

When CRC32c was included in the kernel, Anton ripped out the #ifdefs around reflected polynomials, because CRC32c is always reflected. However, not all CRCs use reflection so we'd like to make it optional. Restore the REFLECT parts from Anton's original CRC32 implementation (https://github.com/ant

[PATCH 3/4] crypto: powerpc - Add CRC-T10DIF acceleration

T10DIF is a CRC16 used heavily in NVMe. It turns out we can accelerate it with a CRC32 library and a few little tricks. Provide the accelerator based the refactored CRC32 code. Cc: Anton Blanchard Thanks-to: Hong Bo Peng Signed-off-by: Daniel Axtens --- arch/powerpc/crypto/Makefile

[PATCH 4/4] crypto: powerpc - Stress test for vpmsum implementations

vpmsum implementations often don't kick in for short test vectors. This is a simple test module that does a configurable number of random tests, each up to 64kB and each with random offsets. Both CRC-T10DIF and CRC32C are tested. Cc: Anton Blanchard Signed-off-by: Daniel Axtens -- Not super f

aes_ctrby8_avx-x86_64.S uses the C preprocessor for token pasting of character sequences that are not valid preprocessor tokens. While this is allowed when preprocessing assembler files it exposes an incompatibilty between the clang and gcc preprocessors where clang does not strip leading white spa
