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 v5: - Enabled `i2s5_8ch` and `i2s6_8ch` CPU DAIs to resolve probe deferral issues for `hdmi0_sound` and `hdmi1_sound`. 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 Hrushiraj Gandhi (3): dt-bindings: vendor-prefixes: add vicharak dt-bindings: arm: rockchip: add Vicharak Axon board arm64: dts: rockchip: add Vicharak Axon board .../devicetree/bindings/arm/rockchip.yaml | 5 + .../devicetree/bindings/vendor-prefixes.yaml | 2 + arch/arm64/boot/dts/rockchip/Makefile | 1 + .../dts/rockchip/rk3588-vicharak-axon.dts | 991 ++++++++++++++++++ 4 files changed, 999 insertions(+) create mode 100644 arch/arm64/boot/dts/rockchip/rk3588-vicharak-axon.dts -- 2.47.3
