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.

Still something more need to support:
(1) Support switching sd detect to gpio irq wakeup when calling
runtime PM.
(2) Then we could disable/enable biu_clk and add off/on genpd
for runtime PM
(3) remove dw_mci_suspend/resume and migrate dw_mci variant driver
to use dw_mci_runtime_suspend/resume(Although I am not so sure)



Shawn Lin (2):
mmc: dw_mmc: add runtime PM callback
mmc: dw_mmc-rockchip: add runtime PM support
