Subject: [PATCH 2/2] arm64: dts: rockchip: Add Vicharak Vaaman2 board
Date: Sat, 27 Jun 2026 15:08:30 +0530 [thread overview]
Message-ID: <20260627093831.80495-3-hrushirajg23@gmail.com> (raw)
In-Reply-To: <20260627093831.80495-1-hrushirajg23@gmail.com>
Add device tree for the Vicharak Vaaman2, a single-board computer
based on the Rockchip RK3588 SoC.
The board features:
- RK3588 SoC with 4x Cortex-A76 (big) + 4x Cortex-A55 (little)
- eMMC storage via SDHCI (HS400)
- microSD card via SDMMC
- RK806 PMIC on SPI2 providing all required power domains
- Two RK8602/RK8603 CPU regulators on I2C0 (big clusters)
- RK8602 NPU regulator on I2C1
- HYM8563 RTC on I2C0
- Status LED on GPIO2_C5 (active-low, heartbeat trigger)
- UART2 as serial console at 1500000 baud
- SARADC with 1.8V reference
