[PATCH] dt-bindings: crypto: samsung: Convert SSS and SlimSSS bindings to json-schema
From: Krzysztof Kozlowski
Date: Sat Sep 07 2019 - 07:34:40 EST
Convert Samsung Exynos Security SubSystem (SSS) and SlimSSS hardware
crypto accelerator bindings to DT schema format using json-schema.
Signed-off-by: Krzysztof Kozlowski <krzk@xxxxxxxxxx>

-Samsung SoC SlimSSS (Slim Security SubSystem) module
-
-The SlimSSS module in Exynos5433 SoC supports the following:
--- Feeder (FeedCtrl)
--- Advanced Encryption Standard (AES) with ECB,CBC,CTR,XTS and (CBC/XTS)/CTS
--- SHA-1/SHA-256 and (SHA-1/SHA-256)/HMAC
-
-Required properties:
-
-- compatible : Should contain entry for slimSSS version:
- - "samsung,exynos5433-slim-sss" for Exynos5433 SoC.
-- reg : Offset and length of the register set for the module
-- interrupts : interrupt specifiers of SlimSSS module interrupts (one feed
- control interrupt).
-
-- clocks : list of clock phandle and specifier pairs for all clocks listed in
- clock-names property.
-- clock-names : list of device clock input names; should contain "pclk" and
- "aclk" for slim-sss in Exynos5433.
