Subject: [PATCH v3 1/3] arm64: dts: amlogic: meson-axg: Disable nfc node by default
Date: Wed, 17 Jun 2026 16:22:32 +0800 [thread overview]
Message-ID: <20260617082239.645562-2-jerrysteve1101@gmail.com> (raw)
In-Reply-To: <20260617082239.645562-1-jerrysteve1101@gmail.com>
nand_rb0 and emmc_ds share one pad. Before enabling nand_rb0 for nfc,
disable nfc nodes by default to resolve pinctrl resource contention.
No mainline AXG boards enable nfc currently thus no extra DTS adjustments
are needed.
