Subject: [PATCH 2/3] ARM: OMAP4: hwmod data: add aes
Date: Sat, 10 Jun 2017 01:12:05 +0200	[thread overview]
Message-ID: <20170609231206.19798-3-sre@kernel.org> (raw)
In-Reply-To: <20170609231206.19798-1-sre@kernel.org>

This fixes the following error during kernel boot:

platform 4b501000.aes: Cannot lookup hwmod 'aes'

Unfortunately the AES module is only documented partly
in the OMAP4430 TRM. I found an old patch from Joel,
which I took over and updated for currently mainline.
