From b99b8832e4c90be199647bdd03a96d08b2000dce Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 24 May 2017 11:06:16 +0800 Subject: [PATCH] ARM: sun8i: a83t: Add device node and pinmux setting for RSB controller The A83T has an RSB controller for talking to the PMIC and audio codec. Add a device node for it. Since there is only one usable pinmux setting, for it, add that as well.
