Add USB phy and controller related nodes
Signed-off-by: Varadarajan Narayanan <quic_varada@quicinc.com>
---
Changes in v8:
- Change clocks order to match the bindings
Changes in v7:
- Change com_aux -> cfg_ahb
Changes in v6:
- Introduce fixed regulators for the phy
- Resolved all 'make dtbs_check' messages
Changes in v5:
- Fix additional comments
- Edit nodes to match with qcom,sc8280xp-qmp-usb3-uni-phy.yaml
- 'make dtbs_check' giving the following messages since
ipq9574 doesn't have power domains. Hope this is ok
/local/mnt/workspace/varada/varda-linux/arch/arm64/boot/dts/qcom/ipq9574-al02-c7.dtb: phy@7d000: 'power-domains' is a required property

From schema: /local/mnt/workspace/varada/varda-linux/Documentation/devicetree/bindings/usb/qcom,dwc3.yaml
Changes in v4:
- Use newer bindings without subnodes
- Fix coding style issues
Changes in v3:
- Insert the nodes at proper location
Changes in v2:
- Fixed issues flagged by Krzysztof
- Fix issues reported by make dtbs_check
- Remove NOC related clocks (to be added with proper
interconnect support)

The node names do not look generic enough. Please take a look at other
platforms.

This also doesn't look correct. This regulator should not just fill the
gap. Does it represent a generic voltage network on the board?
Please do not add 'dummy' voltage regulators if there is no real voltage
wire.

These are real voltage wires. I used dummy since they are
always-on and cannot be increased/decreased (i.e. fixed).
Would something along the following lines be appropriate?
vreg_ae10_3p3: s3300 {
compatible = "regulator-fixed";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-boot-on;
regulator-always-on;
regulator-name = "usb-phy-vdd";
};
vreg_ad8_1p8: s1800 {
compatible = "regulator-fixed";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-boot-on;
regulator-always-on;
regulator-name = "usb-phy-pll";
};
vreg_ad9_0p925: s0925 {
compatible = "regulator-fixed";
regulator-min-microvolt = <925000>;
regulator-max-microvolt = <925000>;
regulator-boot-on;
regulator-always-on;
regulator-name = "usb-phy";
};
Thanks

Still not fully correct. Please use regulator name that corresponds to
the power grid on the board schematics. I don't think that you have a
separate power grids for USB PHY.

Naming suggests that these voltages are generated by some PMIC. Is
this correct? If so, please describe the PMIC instead.

SS PHY needs two supplies and HS PHY needs three supplies. 3.3V
and 0.925V are from fixed DC - DC regulators and 1.8V is
generated from MP5496 PMIC. Would the following node definitions
be ok?
usb_hs_vreg0: usb_hs_vreg0 {
compatible = "regulator-fixed";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-boot-on;
regulator-always-on;
regulator-name = "usb-phy-vdd";
};
usb_hs_vreg1: usb_hs_vreg1 {
compatible = "regulator-fixed";
regulator-min-microvolt = <925000>;
regulator-max-microvolt = <925000>;
regulator-boot-on;
regulator-always-on;
regulator-name = "usb-phy";
};
&rpm_requests {
regulators {
compatible = "qcom,rpm-mp5496-regulators";
.
.
.
ipq9574_l2: l2 {
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-boot-on;
regulator-always-on;
};
};
};
Thanks

Again. The voltage rails on the board are not USB-specific, are they? So
why are you declaring usb-phy regulators? Would another consumer of 3.3V
rail use the same usb-phy-vdd regulator?

Ok. Will rename them as follows
usb_hs_vreg0 -> fixed_3p3
usb_hs_vreg1 -> fixed_0p925
regulator-name = "usb-phy-vdd"; -> fixed_3p3
regulator-name = "usb-phy"; -> fixed_0p925
