Nothing prevents you from detailing in ACPI or DT sub-components of a
larger HW block, if there is such a desire, but just make it in a way
that it looks like what would be done for e.g: separate discrete parts,
only the parenting of nodes would change.
So instead of just having a single property, instead create a child node
just for the SGMII phy, with its own compatible string and various other
properties (like interrupt and base register)? That's not a bad idea.
I need help getting this to work.
emac0: ethernet@38800000 {
compatible = "qcom,qdf2432-emac";
reg-names = "base", "csr";
reg = <0x0 0x38800000 0x0 0x10000 >,
<0x0 0x38816000 0x0 0x1000>,
<0x0 0x3881C000 0x0 0x4000>;
interrupts = <0 0x100 0 0 0x104 0>;
interrupt-names = "core0", "sgmii";
sgmii-handle = <&emac_sgmii>;
phy-handle = <&phy0>;
#address-cells = <1>;
#size-cells = <0>;
phy0: ethernet-phy@4 {
reg = <4>;
};
};
emac_sgmii: ethernet-phy@410400 {
compatible = "qcom,qdf2432-emac-phy";
reg = <0x0 0x00410400 0x0 0x100>;
interrupts = <0 0x104 0>;
};
When my driver probes, the platform_device object points to the emac0
node, as always.
How do I parse the emac_sgmii node? How do I get functions like
platform_get_resource() to work? How do I create a new platform_device
object that points to the emac_sgmii node?
