LABBE Corentin fea4045153 crypto: qce - dma_map_sg can handle chained SG
The qce driver use two dma_map_sg path according to SG are chained
or not.
Since dma_map_sg can handle both case, clean the code with all
references to sg chained.

Thus removing qce_mapsg, qce_unmapsg and qce_countsg functions.

Cristian Stoica 5be4d4c94b crypto: replace scatterwalk_sg_next with sg_next
Modify crypto drivers to use the generic SG helper since
both of them are equivalent and the one from crypto is redundant.

Wolfram Sang 3b1b4f540d crypto: qce: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Linus Torvalds f89f4a06a5 Fix up missing dmaengine header inclusion from qce crypto engine
Commit 7bced39751 ("net_dma: simple removal") removed the long-dead
net_dma code, but unintentionally broke the build for the qualcomm
crypto engine (qce) that had accidentally depended on the inclusion of
<linux/dmaengine.h> through the networking header files that used to
have it.

Add the required dmaengine.h include explicitly to fix the breakage.

Stanimir Varbanov ec8f5d8f6f crypto: qce - Qualcomm crypto engine driver
The driver is separated by functional parts. The core part
implements a platform driver probe and remove callbaks.
The probe enables clocks, checks crypto version, initialize
and request dma channels, create done tasklet and init
crypto queue and finally register the algorithms into crypto
core subsystem.

- DMA and SG helper functions
 implement dmaengine and sg-list helper functions used by
 other parts of the crypto driver.

- ablkcipher algorithms
 implementation of AES, DES and 3DES crypto API callbacks,
 the crypto register alg function, the async request handler
 and its dma done callback function.

- SHA and HMAC transforms
 implementation and registration of ahash crypto type.
 It includes sha1, sha256, hmac(sha1) and hmac(sha256).

- infrastructure to setup the crypto hw
 contains functions used to setup/prepare hardware registers for
 all algorithms supported by the crypto block. It also exports
 few helper functions needed by algorithms:
	- to check hardware status
	- to start crypto hardware
	- to translate data stream to big endian form

 Adds register addresses and bit/masks used by the driver
 as well.
