This -is because the mux driver (tc7usb40mu) hasn't been merged. -Without that driver, we can't toggle the GPIO going to the mux to -route out the D+/D- lines to the USB hub that's on the board. - -One solution would be to totally revert this change, but that -opens us up to other problems when two USB drivers are operating -the same hardware block at the same time. Let's modify the DT so -that the USB controller is always in host mode and connected to -the hub so that things like USB keyboards and mouses work. This -is the mode that most people prefer anyway with these devices. We -also delete the usb-switch node because the binding was never -accepted upstream. - -In the future, we can add muxing support and then update the DT -to support both modes at runtime. Patches to support this are -already on the mailing list. - -Fixes: ed75d6a96905 ("arm64: dts: qcom: Collapse usb support into one node") -Reported-by: Rob Clark <robdclark@gmail.com> -Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> ---- - -I noticed that I accidently removed the vbus notifier part of the phy. -Without it, we'll change settings that shouldn't changed. The thing -that we don't have is the ID pin on this board, not the vbus. That's -the only difference from v1. - - arch/arm64/boot/dts/qcom/apq8016-sbc-pmic-pins.dtsi | 1 + - arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi | 13 ++++--------- - 2 files changed, 5 insertions(+), 9 deletions(-) - -diff --git a/arch/arm64/boot/dts/qcom/apq8016-sbc-pmic-pins.dtsi b/arch/arm64/boot/dts/qcom/apq8016-sbc-pmic-pins.dtsi -index d94640812194..790b7775b901 100644 ---- a/arch/arm64/boot/dts/qcom/apq8016-sbc-pmic-pins.dtsi -+++ b/arch/arm64/boot/dts/qcom/apq8016-sbc-pmic-pins.dtsi -@@ -17,6 +17,7 @@ - function = PMIC_GPIO_FUNC_NORMAL; - power-source = <PM8916_GPIO_VPH>; - input-disable; -+ output-high; - }; - }; - -diff --git a/arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi b/arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi -index bd310ac1967a..bb9e29e6b164 100644 ---- a/arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi -+++ b/arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi -@@ -213,11 +213,14 @@ - }; - - usb@78d9000 { -- extcon = <&usb_id>, <&usb_id>; -+ extcon = <&usb_id>; - status = "okay"; - adp-disable; - hnp-disable; - srp-disable; -+ dr_mode = "host"; -+ pinctrl-names = "default"; -+ pinctrl-0 = <&usb_sw_sel_pm>; - ulpi { - phy { - v1p8-supply = <&pm8916_l7>; -@@ -342,14 +345,6 @@ - pinctrl-0 = <&usb_id_default>; - }; - -- usb-switch { -- compatible = "toshiba,tc7usb40mu"; -- switch-gpios = <&pm8916_gpios 4 GPIO_ACTIVE_HIGH>; -- extcon = <&usb_id>; -- pinctrl-names = "default"; -- pinctrl-0 = <&usb_sw_sel_pm>; -- }; -- - hdmi-out { - compatible = "hdmi-connector"; - type = "a"; |
