The spi nor controller of mt8186 has some differences, it needs one more clk, axi_s, for dma feature. And also needs one extra dummy bit when read flash registers. The version 2 patches fix some typos for bindings file, correct return value of probe function in spi-mtk-nor.c file, and add some comments to explain why add extra dummy bit.
