From 81bd0ad07c27ee221c48f5553acf53a86827b439 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Fri, 28 Jul 2017 11:37:57 +0200 Subject: [PATCH] rockchip: rk3368: syscon: SGRF support for OF_PLATDATA In TPL we will need to configure security in the SGRF of the RK3368. This change adds support for the SGRF as a syscon device, so we can retrieve its address range through the syscon API in TPL (and can avoid having to hard-code the address).
