From a6ab6402c4e5ffd3379ba6adfbd2c74101a879c0 Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Tue, 6 Mar 2018 00:21:00 +0200 Subject: [PATCH] hwrng: mxc-rnga - add driver support on boards with device tree The driver works well on i.MX31 powered boards with device description taken from board device tree, the only change to add to the driver is the missing OF device id, the affected list of included headers and indentation in platform driver struct are beautified a little.
