This series adds initial support for the Vicharak Vaaman, an
RK3399-based single-board computer.
Patch 1 documents the "vicharak,vaaman" compatible string in the
Rockchip arm bindings.
Patch 2 adds the board devicetree, enabling the RK808 PMIC with
SYR827/SYR828 CPU-big/GPU regulators, Mali GPU, Gigabit Ethernet,
eMMC, microSD, SARADC/TSADC, and UART2 console.
Tested by booting to a userspace shell over serial and verifying
eMMC/microSD storage and Ethernet.

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, via &gmac)
- eMMC (HS400, enhanced strobe)
- microSD card slot
- SARADC and TSADC
- PWM-based vdd_log regulator
- UART2 serial console
Tested by booting to a userspace shell over the serial console and
verifying eMMC and microSD storage, and Ethernet link-up.
