From 4418ba9a0bb105f00259d10ceb16f9e27199e9b0 Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Wed, 20 Jan 2016 11:40:43 +0100
Subject: [PATCH 040/102] soc: mediatek: PMIC wrap: add mt6323 slave support
Add support for MT6323 slaves. This PMIC can be found on MT2701 and MT7623
EVB. The only function that we need to touch is pwrap_init_cipher().
