Subject: Re: [PATCH v3 0/4] clk: Baikal-T1 DDR/PCIe resets and some xGMAC
 fixes

Hello Stephen, Michael

The series has been here for about two months with no comments. Seeing
the dependent patches won't be merged in before the next merge window,
could you please merge this series in through your repo?
