This patch adds softreset, powerdown and picophy reset controllers for the STiH407 SoC. With this patch three new devices are registered: - 1. st,stih407-powerdown 2. st,stih407-softreset 3. st,stih407-picophyreset All three devices use system configuration registers mapped via regmap to perform the reset or powerdown. The powerdown controller also has an acknowledgement. A separate picophy reset controller manages the different reset channels within the picophy, which have a different polarity to the other system softresets. Managing these different picophy softreset channels is necessary to correctly handle resuming from suspend when USB2 devices are plugged into the USB3 port.
