* ARM: dts: meson: fixing USB support on Meson8b @ 2017-09-20 14:38 Emiliano Ingrassia 2017-09-22 6:59 ` Martin Blumenstingl 0 siblings, 1 reply; 4+ messages in thread From: Emiliano Ingrassia @ 2017-09-20 14:38 UTC (permalink / raw) To: linus-amlogic This patch fixes the Meson8b USB1 dts node, changing the IRQ type from edge rising to level high. This avoids errors like "usb 1-1-port1: cannot reset (err = -110)" on Odroid-C1+ board. The patch also improves the same node adding the description of the digital and analog regulators found in DWC2 USB controller.

The voltage values were taken from a comment regarding the dwc2_hstog_supply_names array, in drivers/usb/dwc2/core.h.

I see - those boards seem to use a real regulator for these supplies (which needs to be turned on, which is why they are configuring it). maybe we should get feedback from the dwc2 maintainers here >> are you trying to fix a separate problem here? >> > > Nothing in particular, just trying to avoid the messages: > "Looking up vusb_d-supply property in node /soc/usb at c90c0000 failed" and > "Looking up vusb_a-supply property in node /soc/usb at c90c0000 failed". > > The voltage values were taken from a comment regarding the dwc2_hstog_supply_names > array, in drivers/usb/dwc2/core.h. > > Do you think that should be in a separate patch or require a better investigation? yes, I think a separate patch would be good if it is really needed then we need something similar for GXBB as well >> can you add the following line before your Signed-off-by please: >> Fixes: e29b1cf87473 ("ARM: dts: meson: add USB support on Meson8 and Meson8b") >> > > Of course. thank you! >> > Signed-off-by: Emiliano Ingrassia <ingrassia@epigenesys.com> >> > --- >> > arch/arm/boot/dts/meson8b.dtsi | 19 +++++++++++++++++++ >> > 1 file changed, 19 insertions(+) >> > >> > diff --git a/arch/arm/boot/dts/meson8b.dtsi b/arch/arm/boot/dts/meson8b.dtsi >> > index bc278da7df0d..3306bff3d44d 100644 >> > --- a/arch/arm/boot/dts/meson8b.dtsi >> > +++ b/arch/arm/boot/dts/meson8b.dtsi >> > @@ -87,6 +87,22 @@ >> > compatible = "arm,cortex-a5-scu"; >> > reg = <0xc4300000 0x100>; >> > }; >> > + >> > + soc { >> > + vusb_d: regulator-vusb_d { >> > + compatible = "regulator-fixed"; >> > + regulator-name = "vusb_d"; >> > + regulator-min-microvolt = <1200000>; >> > + regulator-max-microvolt = <1200000>; >> > + }; >> > + >> > + vusb_a: regulator-vusb_a { >> > + compatible = "regulator-fixed"; >> > + regulator-name = "vusb_a"; >> > + regulator-min-microvolt = <1100000>; >> > + regulator-max-microvolt = <1100000>; >> > + }; >> > + }; >> > }; /* end of / */ >> > >> > &aobus { >> > @@ -214,6 +230,9 @@ >> > >> > &usb1 { >> > compatible = "amlogic,meson8b-usb", "snps,dwc2"; >> > + interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>; >> I checked Amlogic's code: even Meson6 uses IRQ_TYPE_LEVEL_HIGH >> (drivers/amlogic/usb/dwc_otg/310/dwc_otg_pcd_linux.c in Amlogic's 3.10 >> kernel sources) >> can you please update meson.dtsi (instead of just updating >> meson8b.dtsi) and do the same for the usb0 node? >> > > Ok, I just submitted a new patch with the suggested corrections. perfect, I will check that in a minute >> > + vusb_d-supply = <&vusb_d>; >> > + vusb_a-supply = <&vusb_a>; >> > clocks = <&clkc CLKID_USB1_DDR_BRIDGE>; >> > clock-names = "otg"; >> > }; >> > -- >> > 2.14.1 >> > >> > >> > _______________________________________________ >> > linux-amlogic mailing list >> > linux-amlogic at lists.infradead.org >> > http://lists.infradead.org/mailman/listinfo/linux-amlogic >> >> >> Regards, >> Martin > > Regards, > > Emiliano Regards, Martin ^ permalink raw reply [flat|nested] 4+ messages in thread
