This DT property can be removed and ecc step size can be assigned in driver with 512 value. Signed-off-by: Abhishek Sahu --- Currently there is no user in mainline linux kernel for QPIC. Following patches for this node is in review https://patchwork.kernel.org/patch/10426405/ https://patchwork.kernel.org/patch/10426385/ If these changes got merged then I will submit another change to remove the nand-ecc-step-size from actual DTS. * Changes from v2: NEW CHANGE Documentation/devicetree/bindings/mtd/qcom_nandc.txt | 3 --- 1 file changed, 3 deletions(-) diff --git a/Documentation/devicetree/bindings/mtd/qcom_nandc.txt b/Documentation/devicetree/bindings/mtd/qcom_nandc.txt index f246aa0..1123cc6 100644 --- a/Documentation/devicetree/bindings/mtd/qcom_nandc.txt +++ b/Documentation/devicetree/bindings/mtd/qcom_nandc.txt @@ -45,7 +45,6 @@ Required properties: number (e.g., 0, 1, 2, etc.) - #address-cells: see partition.txt - #size-cells: see partition.txt -- nand-ecc-step-size: must be 512. see nand.txt for more details.
