 We can disable in base dtsi itself.

+			serial_1_pins: serial1_pinmux {
+				mux {
+					pins = "gpio8", "gpio9";
+					function = "blsp_uart1";

+
+			spi_0_pins: spi_0_pinmux {
+				mux {
+					pins = "gpio13", "gpio14",
"gpio15";
+					function = "blsp_spi0";
+					bias-disable;
+				};
+				cs1 {
+					pins = "gpio12";
+					function = "gpio";
+				};
+				host_int1 {
+					pins = "gpio10";
+					function = "gpio";
+					input;
+				};
+				cs2 {
+					pins = "gpio45";
+					function = "gpio";
+				};
+				host_int2 {
+					pins = "gpio61";
+					function = "gpio";
+					input;
+				};
+				rst {
+					pins = "gpio36";
+					function = "gpio";
+					output-high;
+				};

 Normally spi pins should contains spi protocol related pins
 could you please explain what is the role of host_pin and rst
 pins and which driver will use these.

 From pinmux, it looks like multiple gpio based cs are being
 used so do we need to specify cs-gpios like dk01-c2.

 Thanks,
 Abhishek
