Subject: [PATCH 03/14] Documentation/bindings: crypto: inside-secure: update the compatibles
Date:   Thu, 28 Jun 2018 17:15:33 +0200
Message-Id: <20180628151544.22134-4-antoine.tenart@bootlin.com>
In-Reply-To: <20180628151544.22134-1-antoine.tenart@bootlin.com>
References: <20180628151544.22134-1-antoine.tenart@bootlin.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The compatibles were updated in the Inside Secure SafeXcel cryptographic
driver, as the ones previously used were not specific enough. The old
compatibles are still supported by the driver for backward
compatibility.

This patch updates the documentation accordingly.

 - reg: Base physical address of the engine and length of memory mapped region.
 - interrupts: Interrupt numbers for the rings and engine.
 - interrupt-names: Should be "ring0", "ring1", "ring2", "ring3", "eip", "mem".

+Backward compatibility:
+Two compatibles are kept for backward compatibility, but shouldn't be used for
