2017-01-23crypto: mediatek - fix typo and indentationRyder Lee
Dummy patch to fix typo and indentation. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2017-01-23crypto: mediatek - fix incorrect data transfer resultRyder Lee
This patch fixes mtk_aes_xmit() data transfer bug. The original function uses the same loop and ring->pos to handle both command and result descriptors. But this produces incomplete results when src.sg_len != dst.sg_len. To solve the problem, we splits the descriptors into different loops and uses cmd_pos and res_pos to record them respectively.

2017-01-23crypto: mediatek - move HW control data to transformation contextRyder Lee
This patch moves hardware control block members from mtk_*_rec to transformation context and refines related definition. This makes operational context to manage its own control information easily for each DMA transfer.

2017-01-13crypto: mediatek - fix format string for 64-bit buildsArnd Bergmann
After I enabled COMPILE_TEST for non-ARM targets, I ran into these warnings: crypto/mediatek/mtk-aes.c: In function 'mtk_aes_info_map': crypto/mediatek/mtk-aes.c:224:28: error: format '%d' expects argument of type 'int', but argument 3 has type 'long unsigned int' [-Werror=format=] dev_err(cryp->dev, "dma %d bytes error\n", sizeof(*info)); crypto/mediatek/mtk-sha.c:344:28: error: format '%d' expects argument of type 'int', but argument 3 has type 'long unsigned int' [-Werror=format=] crypto/mediatek/mtk-sha.c:550:21: error: format '%u' expects argument of type 'unsigned int', but argument 4 has type 'size_t {aka long unsigned int}' [-Werror=format=] The correct format for size_t is %zu, so use that in all three cases.

2017-01-13crypto: mediatek - don't return garbage err on successful returnColin Ian King
In the case where keylen <= bs mtk_sha_setkey returns an uninitialized return value in err. Fix this by returning 0 instead of err. Issue detected by static analysis with cppcheck. Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2016-12-27crypto: mediatek - Add crypto driver support for some MediaTek chipsRyder Lee
This adds support for the MediaTek hardware accelerator on mt7623/mt2701/mt8521p SoC. This driver currently implement: - SHA1 and SHA2 family(HMAC) hash algorithms. - AES block cipher in CBC/ECB mode with 128/196/256 bits keys.
