From 9885b1bd953640abb7c1de158a2475f23ee13fc8 Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Tue, 6 Mar 2018 00:20:59 +0200 Subject: [PATCH] dt-bindings: rng: Document Freescale i.MX21 and i.MX31 RNGA compatibles Freescale i.MX21 and i.MX31 SoCs contain a Random Number Generator Accelerator module (RNGA), which is replaced by RNGB and RNGC modules on later i.MX SoC series, the change adds a new compatible property to describe the controller. Since all versions of Freescale RNG modules are legacy, apparently the documentation file has no more potential for further extensions, nevertheless generalize it by removing explicit RNGC specifics.
