Subject: [PATCH v4 0/9] Add MediaTek MT7986 SPI NAND and ECC support

This patch series add MediaTek MT7986 SPI NAND and ECC controller
support, split ECC engine with rawnand controller in bindings and
change to YAML schema.

Changes since V3:
 - Correct mediatek,mtk-nfc.yaml dt-bindings.

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
  dt-bindings: mtd: mediatek,nand-ecc-engine: Add compatible for MT7986
