Subject: [PATCH 00/10] Ambarella CV75 SoC minimal bring-up
Date: Thu, 30 Jul 2026 18:43:20 +0800 [thread overview]
Message-ID: <20260730104330.81367-1-longzhao@ambarella.com> (raw)
This series adds minimal Ambarella CV75 support sufficient for early
bring-up with a serial console.
It introduces DT bindings and drivers for the RCT clock controller,
pinctrl, and UART, plus ARCH_AMBARELLA, a minimal CV75 EVK device tree,
arm64 defconfig entries, and a MAINTAINERS entry.
The goal of this first submission is a small, reviewable console-capable
baseline. Further SoC peripherals can follow in later series.
The series is based on linux-next. It has been booted on CV75
hardware with the serial console working.
Testing:
- Booted to console on CV75 EVK with initramfs
- scripts/checkpatch.pl --strict
- make dt_binding_check DT_SCHEMA_FILES=ambarella
