This series adds initial device tree support for the Vicharak Axon
single-board computer, which is based on the Rockchip RK3588 SoC.

The Vicharak Axon is a feature-rich SBC targeting developer and embedded
use cases. It ships with:

  - Rockchip RK3588 (4x Cortex-A76 + 4x Cortex-A55)
  - RK806 PMIC providing all SoC power domains
  - eMMC 5.1 (on-board) and microSD slot
  - Gigabit Ethernet via RGMII (RTL8211F)
  - Dual HDMI 2.1 output and one HDMI 2.0 input (receiver)
  - PCIe 3.0 x4 and two PCIe 2.0 slots
  - SATA 3.0
  - USB 2.0 host ports (EHCI/OHCI)
  - NXP PCA9554 I/O expander for status LEDs
  - Haoyu HYM8563 RTC

Changes since v4:
- Re-enabled `combphy2_psu` which is a required PHY for `pcie2x1l1`. (It was incorrectly removed in v4 during the unused PHY cleanup).
- Fixed alphabetical sorting of `rk3588-vicharak-axon.dtb` in the Makefile.

Changes since v3:
- Completely removed `sdio_pwrseq` and `wireless-wlan` pinctrl nodes as Wi-Fi/SDIO was already removed.
- Removed unused `u2phy0`, `u2phy0_otg`, `u2phy1`, `u2phy1_otg` nodes to fix orphaned PHY warnings, since the USB 2.0 host ports utilize `u2phy2` and `u2phy3`.

Changes since v2:
- Split the dt-bindings patch into two separate patches: one for the vendor prefix and one for the board binding as requested by Heiko.
- Removed invalid `enable-gpios` property from HDMI nodes (ignored by dw-hdmi-qp binding)
- Fixed copy-paste error in `rk806_dvs1_null` pinctrl node (gpio_pwrctrl2 -> gpio_pwrctrl1)

Changes since v1:
- Renamed the dts file from rk3588-axon.dts to rk3588-vicharak-axon.dts
- Added binding patches for the board (rockchip.yaml) and vendor (vendor-prefixes.yaml)
- Renamed regulator nodes to the standard `regulator-name` pattern
- Removed `mem-supply` properties and phandles from cpu nodes (vendor-kernel specific)
- Fixed pcie20_avdd0v85 vin-supply mismatch
- Removed obsolete `regulator-compatible` property
- Removed invalid `regulator-init-microvolt` property
- Removed dangling `enable-active-high` properties from fixed regulators
- Cleaned up unneeded i2c3 / es8388 nodes
- Added missing `vpcie3v3-supply` properties to PCIe nodes
