Subject: [PATCH 06/14] ARM: rockchip: Add RK3562 KickPi K3 board support
Date: Fri, 16 Jan 2026 20:40:40 +0100 [thread overview]
Message-ID: <20260116-barebox-kickpi-v1-6-d11fbccd527a@gmail.com> (raw)
In-Reply-To: <20260116-barebox-kickpi-v1-0-d11fbccd527a@gmail.com>
KICKPI-K3 is a development board based on Rockchip RK3562, the main
control chip. It has a quad-core 64-bit Cortex-A53 processor, a main
frequency of up to 2.0GHz, low power consumption, and high performance.
