Does the module here refer to the hw component or to the linux kernel
module?

*sigh* Please at least give me a chance to reply to the conversation on
the previous versions of the series before sending more, that's the
second time with this series :/
Right now this looks worse to me than what we started with given the
comment is even broader. I have not changed my mind re: what I said on
the previous version.

Thanks,
Conor.

The module here refers to the hardware component.

My bad, I should have waited for your response. I will hold on posting next
version until your response is received.

OK, so in the previous version [1] your reply was to have specific compatibles
as bindings with "ti-am654-icss-iep" as a fall back. I will go with this only.

Does the below looks good to you? Here "ti,am642-icss-iep" and
"ti,j721e-icss-iep" are different compatibles for different SoCs where as
"ti,am654-icss-iep" is the fall back. Compatible "ti,am654-icss-iep" will go in
the driver.

properties:
  compatible:
    oneOf:
      - items:
          - enum:
              - ti,am642-icss-iep
              - ti,j721e-icss-iep
          - const: ti,am654-icss-iep

      - items:
          - const: ti,am654-icss-iep

examples:
  - |

    /* AM65x */
    icssg0_iep0: iep@2e000 {
        compatible = "ti,am654-icss-iep";
        reg = <0x2e000 0x1000>;
        clocks = <&icssg0_iepclk_mux>;
    };

    /* J721E */
    icssg0_iep0: iep@2f000 {
        compatible = "ti,j721e-icss-iep","ti,am654-icss-iep";
        reg = <0x2e000 0x1000>;
        clocks = <&icssg0_iepclk_mux>;
    };


    /* AM64x */
    icssg0_iep0: iep@2b000 {
        compatible = "ti,am642-icss-iep", "ti,am654-icss-iep";
        reg = <0x2e000 0x1000>;
        clocks = <&icssg0_iepclk_mux>;
    };


Please let me know if the compatible property and the example looks OK to you.
Also please let me know if some other change is required. I will send next
revision after your confirmation.

This one doesn't need to be an items list, since there is only one item.
It should be able to just be const:. I much prefer this approach.

Thanks,
Conor.

Yeah, that looks okay to me, thanks.
