Mikrobus boards config should not live here. It is supposed to be independent of the system and arch. 2. I am going to be cleaning up and sending this once at least the dt-bindings are approved. I have included it in the patch to provide some idea about how it will supposedly look like (and anyone who might want to test this stuff). I will try to remember to add it in diffstat in the future. >> + mikrobus_spi_pins_gpio: mikrobus-spi-gpio-pins { >> + pinctrl-single,pins = < >> + AM62X_IOPAD(0x0194, PIN_INPUT, 7) /* (B19) MCASP0_AXR3.GPIO1_7 */ >> + AM62X_IOPAD(0x0198, PIN_INPUT, 7) /* (A19) MCASP0_AXR2.GPIO1_8 */ >> + AM62X_IOPAD(0x01ac, PIN_INPUT, 7) /* (E19) MCASP0_AFSR.GPIO1_13 */ >> + AM62X_IOPAD(0x01b0, PIN_INPUT, 7) /* (A20) MCASP0_ACLKR.GPIO1_14 */ >> + >; >> + }; > we could potentially get rid of these if we get the gpio-ranges correct > on pinctrl?

Will look into this before sending an actual patch for beagleplay dts as well. Ayush Singh
