Changes since V2:
 - Change ECC err_mask value with GENMASK macro.
 - Change snfi mediatek,rx-latch-latency to mediatek,rx-latch-latency-ns.
 - Add a separate patch for DTS change.
 - Move common description to top-level pattern properties.
 - Drop redundant parts in dt-bindings.

Changes since V1:
 - Use existing sample delay property.
 - Add restricting for optional nfi_hclk.
 - Improve and perfect dt-bindings documentation.
 - Change existing node name to match NAND controller DT bingings.
 - Fix issues reported by dt_binding_check.
 - Fix issues reported by dtbs_check.

Xiangsheng Hou (9):
  spi: mtk-snfi: Change default page format to setup default setting
  spi: mtk-snfi: Add optional nfi_hclk which is needed for MT7986
  mtd: nand: ecc-mtk: Add ECC support fot MT7986 IC
  dt-bindings: spi: mtk-snfi: Add compatible for MT7986
  spi: mtk-snfi: Add snfi sample delay and read latency adjustment
  dt-bindings: spi: mtk-snfi: Add read latch latency property
  dt-bindings: mtd: Split ECC engine with rawnand controller
  arm/arm64: dts: mediatek: Fix existing NAND controller node name

This should be instead:
    $ref: nand-chip.yaml#
    unevaluatedProperties: false

and then properties below (due to current dtschema limitations) should
list properties from nand-controller.yaml:

      nand-on-flash-bbt: true

Optionally, we could create additional schema - nand-controller-chip,
which would be referenced directly by nand-controller and itself would
ref nand-chip.

no need, 0 is the minimum.
