Subject: [PATCH 15/18] crypto: caam - do not use mem and emi_slow clock for imx7x
Date: Mon, 3 Sep 2018 13:24:05 +0200 [thread overview]
Message-ID: <20180903112408.2086-16-m.niestroj@grinn-global.com> (raw)
In-Reply-To: <20180903112408.2086-1-m.niestroj@grinn-global.com>
Pick commit 699e491bac84a2069c7abeacf2f4367ecb19fa9c from Linux
upstream.
crypto: caam - do not use mem and emi_slow clock for imx7x
I.MX7x only use two clocks for the CAAM module, so make sure we do not try to
use the mem and the emi_slow clock when running in that imx7d and imx7s machine
type.
