Subject: [PATCH 3/3] clk: rockchip: include downstream muxes into fractional dividers

From: [email-masked] (Caesar Wang)
Date: Sat, 12 Dec 2015 11:35:27 +0800

Hi Heiko,

There are any chance to add the RK3036 SoCs for muxes into fractional 
dividers?
As the attachment for my test patchs. (fetch from 
https://github.com/rockchip-linux/kernel -b develop-v4.1)

I have fetch this series pacthes for my Kylin board.

Anyway, I will send the patch for RK3036 if this patch has merged into 
mainline.

? 2015?08?22? 01:48, Heiko Stuebner ??:
