This patch adds MT8173 spi bus controllers into device tree. Signed-off-by: Leilk Liu <leilk.liu@mediatek.com> --- Change in this patch: 1. "pad-select" is a vendor property, so change it to "mediatek,pad-select". 2. modify the property of clocks and clock-names. --- arch/arm64/boot/dts/mediatek/mt8173.dtsi | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+)
