Changes in v2:
The power supply is applied to the OTG port.

Hi Heiko,
your approach makes sense, i just tried it and the Type-C port is
still powered-on, like with the previous patch.
But sadly still no data flow.
I have got a gru/kevin and also bought a USB-C to SATA bridge
for it. The bridge works fine on kevin with kernel 4.4, still not
tested with mainline.
But when plugged into the Sapphire there is an LED that shows it
is powered-on and nothing else. On the linux side, dmesg shows no
messages.
Comparing the USB portion of the DTS wrt Firefly i see no
significant differences.
Are there other Sapphire board users that can confirm if the
Type-C port works or not? That would help to discard a HW issue.
Enric was working on a similar board, maybe he remember some
peculiarities.
Hi,
i have taken another look at the USB3 Type-C port of the Sapphire board
and made a little bit of progress. Now there is some data transfer, but
still not working.
Applying this patch:
--- a/arch/arm64/boot/dts/rockchip/rk3399-sapphire.dtsi
+++ b/arch/arm64/boot/dts/rockchip/rk3399-sapphire.dtsi

pinctrl-0 = <&vcc5v0_typec0_en>;

};
and having a memory stick plugged into the port from power-up, the
following happens:
1.- The memory stick LED lights on and kernel reports:
[ 4.782999] scsi 0:0:0:0: Direct-Access USB DISK

2.- 4 seconds later the memory stick LED lights off and kernel reports:
[ 9.082822] phy phy-ff770000.syscon:usb2-phy@e450.2: charger =
USB_DCP_CHARGER
3.- After a minute the kernel reports:
[ 71.666761] usb 5-1: USB disconnect, device number 2
The usb vbus is present all the time, so, it does not look
like an issue of the vcc5v0_typec0 regulator.
Please, can you help me debugging this issue?
Regards,
Vicenç.
