From cfe10d38aa1ae6aaa8979f3eb3695db57863ccd9 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Wed, 22 Aug 2018 10:36:29 -0700 Subject: [PATCH] arm64: dts: qcom: sdm845-mtp: Add nodes for USB Set the various nodes to "okay" and hook up the regulators. NOTE: For now the main USB port (the one that goes out the Type C connector) is forced to host. Eventually someone will need to get the Type C detection hooked up and get this all integrated with the PMI8998 PMIC. The reason for forcing to "host" in the meantime is that this will leave us with one "host" and one "peripheral" port. In order for host mode this to work, we assume that the bootloader left things configured enough for us. Apparently the magic for that is is to do these writes on pmi8998: - pm_comm_write_byte(2, 0x1153, 0x2C, 0); - pm_comm_write_byte(2, 0x1152, 0x07, 0); - pm_comm_write_byte(2, 0x1140, 0x00, 0); - pm_comm_write_byte(2, 0x1140, 0x01, 0); Signed-off-by: Douglas Anderson Reviewed-by: Stephen Boyd Reviewed-by: Bjorn Andersson Signed-off-by: Andy Gross --- arch/arm64/boot/dts/qcom/sdm845-mtp.dts | 61 +++++++++++++++++++++++++++++++++ 1 file changed, 61 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sdm845-mtp.dts b/arch/arm64/boot/dts/qcom/sdm845-mtp.dts index ef53c4a..eedfaf8 100644 --- a/arch/arm64/boot/dts/qcom/sdm845-mtp.dts +++ b/arch/arm64/boot/dts/qcom/sdm845-mtp.dts @@ -356,6 +356,67 @@ status = "okay"; }; +&usb_1 { + status = "okay"; +}; + +&usb_1_dwc3 { + /* Until we have Type C hooked up we'll force this as host. */ + dr_mode = "host"; +}; + +&usb_1_hsphy { + status = "okay"; + + vdd-supply = <&vdda_usb1_ss_core>; + vdda-pll-supply = <&vdda_qusb_hs0_1p8>; + vdda-phy-dpdm-supply = <&vdda_qusb_hs0_3p1>; + + qcom,imp-res-offset-value = <8>; + qcom,hstx-trim-value = ; + qcom,preemphasis-level = ; + qcom,preemphasis-width = ; +}; + +&usb_1_qmpphy { + status = "okay"; + + vdda-phy-supply = <&vdda_usb1_ss_1p2>; + vdda-pll-supply = <&vdda_usb1_ss_core>; +}; + +&usb_2 { + status = "okay"; +}; + +&usb_2_dwc3 { + /* + * Though the USB block on SDM845 can support host, there's no vbus + * signal for this port on MTP.
