[PATCH v2 00/17] Enable Qualcomm Crypto Engine on sm8250
From: Bhupesh Sharma
Date: Wed May 05 2021 - 17:38:01 EST
Changes since v1:
=================
- v1 can be seen here: https://lore.kernel.org/linux-arm-msm/20210310052503.3618486-1-bhupesh.sharma@xxxxxxxxxx/
- v1 did not work well as reported earlier by Dmitry, so v2 contains the following
changes/fixes:
~ Enable the interconnect path b/w BAM DMA and main memory first
before trying to access the BAM DMA registers.
~ Enable the interconnect path b/w qce crytpo and main memory first
before trying to access the qce crypto registers.
~ Make sure to document the required and optional properties for both
BAM DMA and qce crypto drivers.
~ Add a few debug related print messages in case the qce crypto driver
passes or fails to probe.
~ Convert the qce crypto driver probe to a defered one in case the BAM DMA
or the interconnect driver(s) (needed on specific Qualcomm parts) are not
yet probed.
Qualcomm crypto engine is also available on sm8250 SoC.
It supports hardware accelerated algorithms for encryption
and authentication. It also provides support for aes, des, 3des
encryption algorithms and sha1, sha256, hmac(sha1), hmac(sha256)
authentication algorithms.
Tested the enabled crypto algorithms with cryptsetup test utilities
on sm8250-mtp and RB5 board (see [1]).
While at it, also make a minor fix in 'sdm845.dtsi', to make
sure it confirms with the other .dtsi files which expose
crypto nodes on qcom SoCs.
