Subject: [PATCH] arm64: dts: ti: k3-am62p-j722s-common-wakeup: Add GP_SW1 efuse node for silicon revision
Date: Mon, 14 Sep 2026 19:13:04 -0500	[thread overview]
Message-ID: <20260915001304.3781247-1-jm@ti.com> (raw)

Add efuse node for GP_SW1 register at offset 0x230. The GP_SW1
efuse register is used to determine AM62Px silicon revision.
Reference efuse cell from chipid node via nvmem-cells.
