[RFC PATCH v2 0/4] Init runtime PM support for dw_mmc

[Shawn Lin]

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.



Shawn Lin (4):
  mmc: dw_mmc: add runtime PM callback
  mmc: dw_mmc-rockchip: add runtime PM support
  mmc: core: expose the capability of gpio card detect
  mmc: dw_mmc-rockchip: disable biu clk and genpd if possible
