[PATCH v2 0/6] arm64: dts: rockchip: Add ROCK 2A/2F, Sige1 and NanoPi Zero2

[PATCH v2 0/6] arm64: dts: rockchip: Add ROCK 2A/2F, Sige1 and NanoPi Zero2

[Jonas Karlman]

This series adds dt-bindings and initial device tree for the following
Rockchip RK3528A boards:
- Radxa ROCK 2A/2F
- ArmSoM Sige1
- FriendlyElec NanoPi Zero2

The bt/wifi_reg_on pins are described in the device tree using
rfkill-gpio nodes.

Changes in v2:
- Limit sdmmc max-frequency to 100 MHz on ROCK 2A/2F
- Drop clock-output-names prop from rtc node on Sige1 and NanoPi Zero2
- Drop regulator-boot-on from usb 2.0 host regulators on Sige1
- Add bluetooth and wifi nodes on Sige1
- Collect t-b tag for NanoPi Zero2

These boards can be booted from emmc or sd-card using the U-Boot 2025.07
generic-rk3528 target or work-in-progress patches for these boards [1].

The patch "arm64: dts: rockchip: Fix pinctrl node names for RK3528" [2]
is recommended to remove a few CHECK_DTBS=y W=2 node_name_chars_strict
warnings for these boards.

For working bluetooth on ArmSoM Sige1 the patch "arm64: dts: rockchip:
Fix UART DMA support for RK3528" [3] is also required.

Should this label be named as led-0/led-1?

This pinctrl is the same as that of rk3528.dtsi, we can remove it.

BTW there is a fan connector on the board (connected to pwm6m2),
so pwm6 should be enabled.

Is host-wakeup-gpios needed?

The nodes must include 'led' anywhere in their name according to schema:

"""
patternProperties:
  # The first form is preferred, but fall back to just 'led' anywhere in the
  # node name to at least catch some child nodes.
  "(^led-[0-9a-f]$|led)":

Using the color name similar to the the pin labels in schematics made
most sense to me.

Do you want me to change these to conform to the more restricted
^led-[0-9a-f]$ pattern?

I will drop the pinctrl props in a v3.

I only try to enable controllers for devices that are properly described,
so I ignored the pwm-fan and its required pwm6 controller. Mostly
because it make more sense to describe the fan once thermal support is
completed, work [1] currently being blocked by a rk356x otp series [2]
and that depends on a rk3576 thermal series [3].

The host-wakeup interrupt is described using interrupt* props, not
using the deprecated host-wakeup-gpios prop.

Ok, I got it. Is usb2.0 also stuck?

USB2.0 is mostly stuck due to my limited time and possible power-domain,
will try to send the USB2.0 patches to mailing list tomorrow.
