[PATCH v4 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 v4:
- Remove disable-wp prop from sdio0
- Collect r-b and t-b tags

Changes in v3:
- Rename led nodes to led-0/led-1
- Remove pinctrl* props from sdio0
- Collect a-b tags

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].

For working bluetooth on ArmSoM Sige1 the patch "arm64: dts: rockchip:
Fix UART DMA support for RK3528" [2] is required.
