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. Signed-off-by: William Zhang <william.zhang@broadcom.com> --- Changes in v6: - Add other nand ecc properties to the exclude check list - Update the brcm,nand-ecc-use-strap property description Changes in v5: - Update the description for this ecc strap property - Add check to make sure brcm,nand-ecc-use-strap and nand-ecc-strength/brcm,nand-oob-sector-size can not be used at the same time Changes in v4: - Move ecc strap property to this separate patch and remove some non-binding related text from the description Changes in v3: None Changes in v2: None .../bindings/mtd/brcm,brcmnand.yaml | 24 +++++++++++++++++++ 1 file changed, 24 insertions(+)
