Subject: [PATCH] arm64: dts: qcom: ipq8074: Remove unused gpio from QPIC pins
Date: Wed, 13 Mar 2024 11:27:06 +0100 [thread overview]
Message-ID: <20240313102713.1727458-1-frut3k7@gmail.com> (raw)
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.
