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.
