[PATCH v7 0/2] arm64: dts: rockchip: add Vicharak Axon board support

[Hrushiraj Gandhi]

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 v6:
- Dropped vendor-prefixes patch; the vicharak prefix was already
  submitted upstream by another contributor.
- Added Acked-by from Krzysztof Kozlowski to the binding patch.
- Removed redundant status = okay from newly-defined nodes (leds,
  hym8563, pca9554) as noted by Krzysztof Kozlowski.
- Removed stale mmc2 = &sdio alias (sdio was removed in v4).
- Removed leftover #include <dt-bindings/usb/pd.h> (TypeC removed).
- Removed unused fixed regulators: pcie20_avdd0v85, pcie20_avdd1v8,
  pcie30_avdd0v75, pcie30_avdd1v8, sata_vcc_5v0, vcc0_4v0/vcc4v0_sys.

Changes since v5:
- Enabled i2s5_8ch and i2s6_8ch CPU DAIs to resolve probe deferral
  for hdmi0_sound and hdmi1_sound.

Changes since v4:
- Re-enabled combphy2_psu, required PHY for pcie2x1l1.
- Fixed alphabetical sorting of rk3588-vicharak-axon.dtb in Makefile.

Changes since v3:
- Removed sdio_pwrseq and wireless-wlan pinctrl nodes (Wi-Fi removed).
- Removed unused u2phy0, u2phy0_otg, u2phy1, u2phy1_otg nodes.

Changes since v2:
- Split the dt-bindings patch into separate patches as requested.
- Removed invalid enable-gpios from HDMI nodes.
- Fixed copy-paste error in rk806_dvs1_null pinctrl node.

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

[PATCH v7 2/2] arm64: dts: rockchip: add Vicharak Axon board

[Hrushiraj Gandhi]

Add initial support for the Vicharak Axon single-board computer based on
the Rockchip RK3588 SoC.

The board supports:

- eMMC storage
- microSD card
- Gigabit Ethernet
- HDMI output (dual HDMI)
- HDMI input
- USB 2.0 host ports
- PCIe 2.0 slots
- PCIe 3.0 x4 slot
- SATA
- RTC
- Status LEDs

The board uses an RK806 PMIC and provides the regulators required by
the RK3588 SoC.

dt-bindings: arm: rockchip: add Vicharak Axon board

This commit adds the device tree binding for the Vicharak Axon single-board
computer based on the Rockchip RK3588 SoC.

[Severity: Low]
Does the "vicharak" vendor prefix need to be documented in
Documentation/devicetree/bindings/vendor-prefixes.yaml as part of this
change?

It looks like this introduces a new vendor prefix. Without registering it in
the vendor prefixes registry, it might cause a schema validation warning
when running make dt_binding_check.
