Subject: [PATCH v7 0/2] Add support for nuvoton ma35 nand controller

This patch series adds the mtd nand driver for the nuvoton ma35 ARMv8 SoC.
It includes DT binding documentation and the ma35 mtd nand driver.

v7:
  - Update nuvoton,ma35d1-nand.yaml
    - Remove required 'nand-ecc-step-size' and 'nand-ecc-strength'.
    - Add 'reg' for chip select.
  - Update ma35d1 mtd nand driver
    - Update space and comments style.
    - Add chip select setting from DT.
    - Add switch case which supports various ECC configurations.
    - Set reset before NAND controller enable.

v6:
  - Update ma35d1 mtd nand driver
    - Remove extra blank lines and add comments.

v5:
  - Update ma35d1 mtd nand driver
    - Remove unnecessary definitions and comments.
    - Modified DMA API call sequence.
    - Move the ECC check out of the interrupt handler.
      Check it after reading a page.

v4:
  - Update nuvoton,ma35d1-nand.yaml
    - rename 'nuvoton,ma35d1-nand' to 'nuvoton,ma35d1-nand-controller'.
  - Update ma35d1 mtd nand driver
    - Rewrite the NAND driver using the exec_op API.

v3:
  - Update ma35d1 mtd nand driver
    - Release IRQ handler.
    - Remove unused functions.
    - Remove '.owner'.

v2:
  - Update nuvoton,ma35d1-nand.yaml
    - Adjust the order and remove any unnecessary items.
    - Add 'nand-ecc-step-size' and 'nand-ecc-strength' to the required list.
  - Update ma35d1 mtd nand driver
    - Fix coding style.
    - Use 'devm_clk_get' instead of 'of_clk_get'.
    - Use 'dev_err_probe' instead of 'dev_err'.
    - Remove 'pr_info' and 'of_match_ptr'.
    - Remove 'module_init' and 'module_exit'.
