| Series | [v2,1/4] spi: LS7A: Add Loongson LS7A SPI controller driver support | expand |
在 2020/12/8 15:44, Qing Zhang 写道: > add spi and amd node support. Hi Qing, Thanks for your patch. What is AMD node? Also given that different boards may have different flash, is it a wise idea to hardcode here?
