This patch adds basic A3SP pm domain support. Now, below devices can be controled by PM DMAC1/2/3, IPMMU, DDM, FLCTL, SYS-HPB, BBIF1, MSIOF1/2, SCIFA,SCIFB, IIC1, IrDA, USBH, USBDMAC, SDHI0/1/2, TPU, DREQPAK (Sys), MMCIF, RSPI, SIM, USBF Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J.
