[PATCH v5 0/2] arm64: dts: rockchip: Add rk3576 evb2 board

[Chaoyi Chen]

From: Chaoyi Chen <chaoyi.chen@rock-chips.com>

Hi,

This series add support for rk3576 evb2 board.

General features for rk3576 evb2 board:
    - Rockchip RK3576
    - LPDDR4/4X
    - eMMC5.1
    - RK806-2x2pcs + DiscretePower
    - 1x HDMI2.1 TX / HDMI2.0 RX
    - 1x full size DP1.4 TX (Only 2 Lanes)
    - 2x 10/100/1000M Ethernet
    - 5x SATA3.0 7Pin Slot
    - 2x USB3.2 Gen1 Host
    - 3x USB2.0 Host
    - WIFI/BT
    - ...

To make the USB hub work, the additional patch from usb-next is required:

Changes in v5:
- Link to v4: https://lore.kernel.org/all/20260121015357.291-1-kernel@airkyi.com/
- Remove disable-wp for sdio.
- Add vmmc-supply for sdmmc.
- Remove tx-internal-delay-ps for RGMII PHY.

Changes in v4:
- Link to v3: https://lore.kernel.org/all/20260112022823.91-1-kernel@airkyi.com/
- Move the USB hub code into a separate patch series, and that series have
  already been merged into usb-next.
- Fix supply and reset for usb hub.
- Add cd-gpios for sdmmc.

Changes in v3:
- Link to v2: https://lore.kernel.org/all/20260107070322.323-1-kernel@airkyi.com/ 
- Add binding for WCH CH334/CH335 hub controller.
- Add alias for mmc.
- Rename some usb vbus regulator.
- Add DP regulator.
- Change gmac phy-mode to rgmii-id.
- Add target-supply for sata.
- Change vcc-supply for ufshc.
- Add usb hub.
- ...

Changes in v2:
- Link to v1: https://lore.kernel.org/all/20260104023703.118-1-kernel@airkyi.com/
- Enable hdmi_sound and sai6.
- Add more cpu-supply.
- Use regulator to control sata power.
- Remove "cap-mmc-highspeed" prop in sdmmc.
- Add regulator supply for ufshc.
- Add the missing vcc3v3_hubreset regulator.
- Add otg capability for usb_drd0_dwc3.
