Subject: [PATCH v2 3/3] MIPS: CI20: Enable SMP with two CPUs
Date: Mon, 9 Nov 2026 20:31:31 -0800 [thread overview]
Message-ID: <20261110043131.1985993-4-f.fainelli@gmail.com> (raw)
In-Reply-To: <20261110043131.1985993-1-f.fainelli@gmail.com>
From: 周琰杰 (Zhou Yanjie) <zhouyanjie@wanyeetech.com>
Enable both JZ4780 cores now that the generic Ingenic platform provides
secondary CPU reset and mailbox support. The existing device tree
already reserves TCU channels for both per-CPU clock events.
