Subject: Re: [PATCH 2/4] GMAC: modify CRU config for Rockchip RK3288 SoCs
 integrated GMAC

Hi  Roger,

This  patch should be split into two patch, one for clock ID definition,
one for mac related clocks update.

The Subject for clk-rk3288.c should use below prefix:
clk: rockchip: modify clock for mac ...
