Subject: [PATCH v1 3/3] riscv: dts: starfive: Drop unused properties and limit frquency
Date: Wed, 30 Aug 2023 11:18:46 +0800	[thread overview]
Message-ID: <20230830031846.127957-4-william.qiu@starfivetech.com> (raw)
In-Reply-To: <20230830031846.127957-1-william.qiu@starfivetech.com>

Drop unused properties and limit cclk_in to 50M, thus cancelling the
internal frequency and adopting the by-pass mode.

Signed-off-by: William Qiu <william.qiu@starfivetech.com>
