From 280962d413e873c7b2ff82b0767d04c60cbe0615 Mon Sep 17 00:00:00 2001 From: William Zhang Date: Thu, 22 Feb 2024 19:47:51 -0800 Subject: dt-bindings: mtd: brcmnand: Add ecc strap property Add brcm,nand-ecc-use-strap to get ecc and spare area size settings from board boot strap for broadband board designs because they do not specify ecc setting in dts but rather using the strap setting.
