From: Levin Du <[email protected]>
ROC-RK3399-PC is the first power efficient 4GB DDR4 single board
computer with USB 3.0 and Gigabit Ethernet in a form factor compatible
with the Raspberry Pi. It is based on the Rockchip RK3399 SoC, powered
by the Type-C port.
The devicetree currently supports peripherals of:
- Ethernet
- HDMI
- SD Card
- UART2 debug
- USB3
- eMMC

maybe "is a power efficient" instead of "the first" ;-)

I don't think we want to hard-code linux bootargs in the generic devicetree

As Rob noted in the px30 evb patch, there is now a property helping
to drop these long lists of brightness levels, see
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=1e5e7cc794b5a332c23216dade0a2e937d694b7f

The mp8859 seems to be an i2c-device, as also shown by the
nearly empty mp8859 entry below, so shouldn't this regulator
be defined there?

Adding to the Heiko information. Did you try to just remove brightness-levels?
Without this property, the driver computes a default table with the
brightness levels filled with the numbers provided by the CIE 1931
algorithm. That algorithm is used to dim a led for human perception.
Note that the patches needed did not land yet, are in linux-next, and
you will also be interested in apply this patch [1].

Question here. Since mp8859 driver is not mainlined yet. Shall I leave
the regulator here (mp8859 defaults to output 5V) and remove the
mp8859 from the i2c?

This just comes in need of setting GPIO2_A4 (HUB_RST) to high
This dummy regulator should be removed.
I modify the pinctrl of hub_rst to output high:
hub_rst: hub-rst {
rockchip,pins = <2 RK_PA4 RK_FUNC_GPIO &pcfg_output_high>;
};
and add hub_rst to the pinctrl-0 of vcc5v0_host:
vcc5v0_host: vcc5v0-host-regulator {
compatible = "regulator-fixed";
enable-active-high;
gpio = <&gpio1 RK_PA0 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&vcc5v0_host_en &hub_rst>;
regulator-name = "vcc5v0_host";
regulator-always-on;
vin-supply = <&vcc_sys>;
};
Tested show that it works. But is it the recommended way to set this
gpio (HUB_RST) high? BTW, vcc5v0_host is the usb host voltage,
and HUB_RST needs to set high for the usb hub chip to work.

It seems no existing user of fusb302 yet. I take that fcs,int-n
from the driver code. But I look up the binding doc, and come
with this result:
fusb1: usb-typec@22 {
compatible = "fcs,fusb302";
reg = <0x22>;
pinctrl-names = "default";
pinctrl-0 = <&fusb1_int>;
interrupt-parent = <&gpio1>;

Yep, sounds good ... also please add a comment of sorts that this is
temporary until the mp8859 has its own dt-binding.

It seems you can also model usb-hirarchy internals via the devicetree.
I guess for these things like soc-gpios and such. See
Documentation/devicetree/bindings/usb/usb-device.txt
While I don't know if this can handle such reset gpios yet, you
could at least move the pinctrl setting there.

looks good, except please move the interrupt* properties between reg
and pinctrl
