From 308607e5545f964ad3917919201ce4d9491f7fdb Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Wed, 23 Oct 2019 11:39:42 -0700 Subject: ARM: dts: Configure omap3 rng MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Looks like omap3 RNG is similar to the omap2 rng, let's get it working by configring the dts node for it. We must also add rng_ick to core_l4_clkdm as noted by Adam Ford. And please note that the RNG is likely disabled on HS devices. At least n900 does not have it accessible, and instead omap3-rom-rng driver must be used. So let's tag RNG as disabled on n900 as noted by Pali Rohár . On am3517 at least the clocks need to be configured to get it working as noted by Adam Ford, so let's tag it disabled for now.
