| Subject | [PATCH v6] arm64: dts: Add spi bus dts |
| Message-ID | <pYjrb-3Ie-3@gated-at.bofh.it> |
This patch adds MT8173 spi bus controllers into device tree.
Signed-off-by: Leilk Liu <leilk.liu@mediatek.com>
---
Change in this patch:
pinctl and pad-select fields are board specific, so move to
mt8173-evb.dtsi, and status = "okay".
