Subject: [PATCH V3 03/11] soc: mediatek: PMIC wrap: add wrapper callbacks for init_reg_clock
Date: Mon, 25 Jan 2016 10:53:16 +0100	[thread overview]
Message-ID: <1453715604-36856-4-git-send-email-blogic@openwrt.org> (raw)
In-Reply-To: <1453715604-36856-1-git-send-email-blogic@openwrt.org>

Split init_reg_clock up into SoC specific callbacks. The patch also
reorders the code to avoid the need for callback function prototypes.
