Same comment as clocks. The parent can be the provider.

Why no header like clocks?

+Cortina Gemini Reset Controller
+
+This reset controller is found in Cortina Systems CS3516 and
+the predecessor StorLink SL3516.
+
+Required properties:
+- compatible: "cortina,gemini-reset"
+- #reset-cells: Must be 1
+
+The Gemini reset controller must be a child node of the
+system controller. Apart from this it follows the standard reset
+controller bindings.
+
+Valid reset line values:
+
+0:  DRAM controller
+1:  Flash controller
+2:  IDE controller
+3:  RAID controller
+4:  Security module
+5:  GMAC0 (ethernet)
+6:  GMAC1 (ethernet)
+7:  PCI host bridge
+8:  USB0 USB host controller
+9:  USB1 USB host controller
+10: General DMA controller
+11: APB bridge
+12: LPC (Low Pin Count) controller
+13: LCD module
+14: Interrupt controller 0
+15: Interrupt controller 1
+16: RTC module
+17: Timer module
+18: UART controller
+19: SSP controller
+20: GPIO0 GPIO controller
+21: GPIO1 GPIO controller
+22: GPIO2 GPIO controller
+23: Watchdog timer
+24: External device reset
+25: CIR module (infrared)
+26: SATA0 SATA bridge
+27: SATA1 SATA bridge
+28: TVE TV Encoder module
+29: Reserved
+30: CPU1 reset
+31: Global soft reset
+
+Example:
+
+syscon: syscon@40000000 {
+	compatible = "cortina,gemini-syscon", "syscon", "simple-mfd";
+	reg = <0x40000000 0x1000>;
+
+	reset-controller {
