From 2d94dfc438853dca9b390a3f32fe5331c336fd28 Mon Sep 17 00:00:00 2001 From: Aswath Govindraju Date: Thu, 12 Jan 2023 17:28:46 +0100 Subject: [PATCH] arm64: dts: ti: k3-am625-sk: Add support for USB AM62 SoC has two instances of USB and they are brought on to the board in the following way, -> USB0 instance - This is brought out to a USB TypeC connector on board through TPS6598 PD controller. The PD controller should decide the role based on CC pin in the connector. Unfortunately the irq line for the TPS isn't hooked up which is a mode not yet support by the driver (some patches were submitted earlier this year[0]). So for now the PD controller is left out and peripheral mode chosen. -> USB1 instance - This is brought out to a USB TypeA connector on board. Therefore, add the required device tree support for the above in the board dts file. 0: https://lore.kernel.org/lkml/f714ee55-ef47-317d-81b9-57020dda064b@ti.com/T/ Signed-off-by: Aswath Govindraju Signed-off-by: Sjoerd Simons Tested-by: Martyn Welch Signed-off-by: Vignesh Raghavendra Link: https://lore.kernel.org/r/20230112162847.973869-4-sjoerd@collabora.com --- arch/arm64/boot/dts/ti/k3-am625-sk.dts | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-am625-sk.dts b/arch/arm64/boot/dts/ti/k3-am625-sk.dts index 4f179b146cab..6bc7d63cf52f 100644 --- a/arch/arm64/boot/dts/ti/k3-am625-sk.dts +++ b/arch/arm64/boot/dts/ti/k3-am625-sk.dts @@ -24,6 +24,8 @@ spi0 = &ospi0; ethernet0 = &cpsw_port1; ethernet1 = &cpsw_port2; + usb0 = &usb0; + usb1 = &usb1; }; chosen { @@ -284,6 +286,12 @@ AM62X_IOPAD(0x01d4, PIN_INPUT, 7) /* (B15) UART0_RTSn.GPIO1_23 */ >; }; + + main_usb1_pins_default: main-usb1-pins-default { + pinctrl-single,pins = < + AM62X_IOPAD(0x0258, PIN_OUTPUT, 0) /* (F18) USB1_DRVVBUS */ + >; + }; }; &wkup_uart0 { @@ -464,3 +472,22 @@ }; }; }; + +&usbss0 { + status = "okay"; + ti,vbus-divider; +}; + +&usbss1 { + status = "okay"; +}; + +&usb0 { + dr_mode = "peripheral"; +}; + +&usb1 { + dr_mode = "host"; + pinctrl-names = "default"; + pinctrl-0 = <&main_usb1_pins_default>; +}; -- 2.11.0
