Since pci-imx doesn't support runtime power gating this is still always-on unless PCI is disabled/unused. But it's reasonable for an imx board to not have PCI. The current pd_pcie is actually only for PCIE_PHY, the PCIE ip block is actually inside the DISPLAY domain. This is handled by adding the pcie node in both power domains, using multi-pd support. Series is against linux-next. The last patch needs runtime PM in all drivers or it will cause hangs. This means Shawn should hold back on it until the PCI and mxsfb dependencies get merged (both might take a long time). So you can just review that patch and I will resend it later, perhaps in another cycle.
