M4 corresponds to the relationship between ma35d1-cpu800-wb-128m.dts and ma35d1.dts  Issue Date:2025-01-20

"ma35d1.dtsi" determines which ones are used for A35 or M4. If you find the word "SUBM" that means it is for M4.

Please refer to the naming convention:

MA35D1_Buildroot/output/build/arm-trusted-firmware-custom/plat/nuvoton/ma35d1/include/sspcc.h

"ma35d1-cpu800-wb-128m.dts" is the default PIN definition. For example, UART16 is used for M4 in ma35d1.dtsi

  &sspcc {
    gpio_s = <PD6_S>,
        <PD7_S>,
        <PK2_SUBM>,
        <PK3_SUBM>;
