[PATCH v8 0/2] arm64: dts: rockchip: add Vicharak Axon board support

[Hrushiraj Gandhi <hrushirajg23@gmail.com>]

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

Note on vendor prefix: the 'vicharak' prefix was submitted separately
[1], and Krzysztof asked us to drop it from our series [2].

Changes since v7:
- Renamed rk806 DVS pinctrl nodes to have '-pins' suffix to comply
  with the rockchip,rk806.yaml binding (e.g. 'dvs1-null-pins').
  Removed unused DVS pin state nodes (only the three dvs*-null-pins
  states actively used in pinctrl-0 are kept).
- Removed dangling pinctrl-1/pmic-power-off state after removing
  the unused dvs1-pwrdn node.
- Moved 'compatible' before 'reg' in the PMIC node per DT convention.
- Dropped vendor-prefixes.yaml patch (handled separately, see above).
- Verified with dtbs_check: no warnings.
