Subject: [PATCH V4 10/11] soc: mediatek: PMIC wrap: add mt6323 slave support
Date: Wed, 27 Jan 2016 12:29:08 +0100	[thread overview]
Message-ID: <1453894149-44127-10-git-send-email-blogic@openwrt.org> (raw)
In-Reply-To: <1453894149-44127-1-git-send-email-blogic@openwrt.org>

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().
