+Subject: [PATCH] arm64: dts: qcom: ipq8074: Remove unused gpio from QPIC pins
+
+gpio16 will only be used for LCD support, as its NAND/LCDC data[8]
+so its bit 9 of the parallel QPIC interface, and ONFI NAND is only 8
+or 16-bit with only 8-bit one being supported in our case so that pin
+is unused.
+
+It should be dropped from the default NAND pinctrl configuration
+as its unused and only needed for LCD.
