Subject: [PATCH v2 2/2] dt-bindings: mediatek: Add assigned clock property and axi clock in example
Date: Thu, 30 Jun 2022 17:01:57 +0800	[thread overview]
Message-ID: <20220630090157.29486-3-xiangsheng.hou@mediatek.com> (raw)
In-Reply-To: <20220630090157.29486-1-xiangsheng.hou@mediatek.com>

For mt8173, it is needed to add the axi clock for dma mode.
And it is may needed to adjust default spi frequency.
