arm64: dts: rockchip: Add Vicharak Vaaman board
Add initial devicetree support for the Vicharak Vaaman, an RK3399-based single-board computer. Supported peripherals: - RK808 PMIC with core/logic/IO regulators - SYR827/SYR828 (vdd_cpu_b/vdd_gpu) CPU-big and GPU regulators - Mali GPU - Gigabit Ethernet (RGMII, RTL8211E PHY via &gmac with mdio subnode) - eMMC (HS400, enhanced strobe) - microSD card slot - SARADC and TSADC - PWM-based vdd_log regulator - UART2 serial console Signed-off-by: Hrushiraj Gandhi <hrushirajg23@gmail.com> Link: https://patch.msgid.link/20260730045947.388660-3-hrushirajg23@gmail.com Signed-off-by: Heiko Stuebner <heiko@sntech.de>
