Factory default is ICSS1 Ethernet ports (i.e. Jumper not populated). Use the GPIO to detect the jumper setting and configure the pinmux accordingly. Also select the right DT blob based on the chosen configuration. J51 absent -> ICSS1 Ethernet, no LCD on VOUT -> am571x-idk.dtb J51 present -> LCD on VOUT, no ICSS1 Ethernet -> am571x-idk-lcd-osd.dtb At present we only support the assume it is the Legacy LCD. LCD detection mechanism needs to be added later to differentiate between legacy vs new LCD. For ICSS1 Ethernet pins use the following convention to set the pinmux as PMT data is not yet finalized. - If pin is output, set as PIN_OUTPUT - If pin is input and external pull resistor present set as PIN_INPUT - If pin is input and external pull resistor absent, set pull to same as that of the external PHY's internall pull. - Do not use SLEW_CONTROLon any pin.
