Subject: [PATCH resend 02/12] usb: typec: add basic typec properties
Date: Tue, 26 Sep 2017 12:05:13 +0800 [thread overview]
Message-ID: <1506398723-19359-3-git-send-email-jun.li@nxp.com> (raw)
In-Reply-To: <1506398723-19359-1-git-send-email-jun.li-3arQi8VN3Tc@public.gmane.org>
port-type is required for any typec port; default-role is only required
for drp; power source capable needs src-pdos; power sink capable needs
snk-pdos, max-snk-mv, max-snk-ma, op-snk-mw.

+Generic typec and power delivery properties
+-------------------------------------------
+
+Required properties:
+- port-type: should be one of "source", "sink" or "dual".
+- default-role: preferred power role if drp, should be "sink" or "source".
+- src-pdos: An array of u32 with each entry providing supported power
+ source data object(PDO), the detailed bit definitions of
+ PDO can be found in "Universal Serial Bus Power Delivery
+ Specification" chapter 6.4.1.2 Source_Capabilities Message,
+ the order of each entry(PDO) should follow the PD spec chapter
+ 6.4.1. Required only for power source and power dual role with
+ power delivery support.
+- snk-pdos: An array of u32 with each entry providing supported power
+ sink data object(PDO), the detailed bit definitions of PDO
+ can be found in "Universal Serial Bus Power Delivery
+ Specification" chapter 6.4.1.3 Sink Capabilities Message,
+ the order of each entry(PDO) should follow the PD spec chapter
+ 6.4.1. Required only for power sink and power dual role with
+ power delivery support.
+- max-snk-mv: The max voltage the sink can support in millivoltage, required
+ only for power sink and power dual role with power delivery
+ support.
+- max-snk-ma: The max current the sink can support in milliampere, required
+ only for power sink and power dual role with power delivery
+ support.
+- op-snk-mw: Sink required operating power in milliwatts, if source offered
+ power is less then it, Capability Mismatch is set, required
+ only for power sink and power dual role with power delivery
+ support.
+
+Example:
+
+ptn5110@50 {
+ compatible = "usb,tcpci";
+ reg = <0x50>;
+ interrupt-parent = <&gpio3>;
+ interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
+ port-type = "dual";
+ default-role = "sink";
+ src-pdos = <0x380190c8>;
+ snk-pdos = <0x380190c8 0x3802d0c8>;
+ max-snk-mv = <9000>;
+ max-snk-ma = <1000>;
+ op-snk-mw = <9000>;
+};
