Hi Jaehoon and Ulf, This a patchset going to support runtime PM for dw_mmc. Basically it is a prototype design with some redundant code there. But I think it's okay to send it out for sure I am not heading in the wrong direction. For v2, it could support to disable biu_clk and power-off genpd if we find the gpio cd is used.
