Sky Huang 058bd6c9d3 mediatek: filogic: mt7986: fix SPI driving for NAND and increase to 52MHz on ZyXEL EX5601 ... 8mA driving will cause overshoot issue on SPI NAND. Change it to 4mA. - Reference: 003744197a On Linux mainline (mt7986.dtsi), spi's source clock is: clocks = <&topckgen CLK_TOP_MPLL_D2>, which is 208MHz. Usable clock division will be: - 208/4=52MHz - 208/6~=35MHz - 208/8=26MHz and so on If we specify 50MHz for spi-max-frequency, it will actually run under about 35MHz. Most SPI NAND & NOR flashes are capable of running with more than 52MHz, include Micorn MT29F4G01ABAFDWB on ZyXEL EX5601. [Ref: #18752] To reach highest performance on mt7986, use spi-max-frequency = <520000000>. Basically, this setting should work on all mt7986 PCBs since most mt7986 boards follow reference design. However, other boards needs further test to guarantee stability.
