From 4951db7edc9460e5102b9c00b67ceddb09dfbe4c Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Thu, 20 Nov 2014 10:43:23 +0100 Subject: hwrng: atmel - add DT support Add DT support. Make the driver depend on CONFIG_OF as at91sam9g45 was the only SoC making use of the TRNG block and this SoC is now fully migrated to DT.
