"fsl,imx51-src" is the only compatible the driver matches on, but we
have these combinations on compatible SRCs in the device trees:

  "fsl,imx50-src", "fsl,imx51-src"
  "fsl,imx51-src"
  "fsl,imx53-src", "fsl,imx51-src"
  "fsl,imx6q-src", "fsl,imx51-src"
  "fsl,imx6sl-src", "fsl,imx51-src"
  "fsl,imx6sll-src", "fsl,imx51-src"
  "fsl,imx6sx-src", "fsl,imx51-src"
  "fsl,imx6ul-src", "fsl,imx51-src"

That could be described using oneOf and and an items list of const
values per SoC like in the qcom bindings.

Yes, I noticed this and will add all of them in V2 per SoC, thanks.

-Freescale i.MX System Reset Controller
-======================================
-
-Please also refer to reset.txt in this directory for common reset
-controller binding usage.
-
-Required properties:
-- compatible: Should be "fsl,<chip>-src"
-- reg: should be register base and length as documented in the
-  datasheet
-- interrupts: Should contain SRC interrupt and CPU WDOG interrupt,
-  in this order.
-- #reset-cells: 1, see below
-
-example:
-
-src: src@20d8000 {
-        compatible = "fsl,imx6q-src";
-        reg = <0x020d8000 0x4000>;
-        interrupts = <0 91 0x04 0 96 0x04>;
-        #reset-cells = <1>;
-};
-
-Specifying reset lines connected to IP modules
-==============================================
-
-The system reset controller can be used to reset the GPU, VPU,
-IPU, and OpenVG IP modules on i.MX5 and i.MX6 ICs. Those device
-nodes should specify the reset line on the SRC in their resets
-property, containing a phandle to the SRC device node and a
-RESET_INDEX specifying which module to reset, as described in
-reset.txt
-
-example:
-
-        ipu1: ipu@2400000 {
-                resets = <&src 2>;
-        };
-        ipu2: ipu@2800000 {
-                resets = <&src 4>;
-        };
-
-The following RESET_INDEX values are valid for i.MX5:
-GPU_RESET     0
-VPU_RESET     1
-IPU1_RESET    2
-OPEN_VG_RESET 3
-The following additional RESET_INDEX value is valid for i.MX6:
-IPU2_RESET    4
