Just:

         - mediatek,mt8195-spi-slave

Just 'maxItems: 1'

-   -  <&topckgen CLK_TOP_UNIVPLL1_D8>: specify parent clock 78MHZ.
-  The second should be <&topckgen CLK_TOP_SPI_SEL>. It's clock mux.
-  The third is <&pericfg CLK_PERI_SPI0>. It's clock gate.
-
-- clock-names: shall be "parent-clk" for the parent clock, "sel-clk" for the
-  muxes clock, and "spi-clk" for the clock gate.
-
-Optional properties:
--cs-gpios: see spi-bus.txt.
-
-- mediatek,pad-select: specify which pins group(ck/mi/mo/cs) spi
-  controller used. This is an array, the element value should be 0~3,
-  only required for MT8173.
-    0: specify GPIO69,70,71,72 for spi pins.
-    1: specify GPIO102,103,104,105 for spi pins.
-    2: specify GPIO128,129,130,131 for spi pins.
-    3: specify GPIO5,6,7,8 for spi pins.

-
