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.

v11:
  - Update ma35d1 mtd nand driver
    - Fix warnings and checks use --strict.

v10:
  - Update ma35d1 mtd nand driver
    - Add unsupported write page handling.

v9:
  - Update ma35d1 mtd nand driver
    - Remove NAND_NO_SUBPAGE_WRITE flag.
    - Remove of_get_property().
    - Add ecc.write_subpage and ecc.read_subpage.

v8:
  - Update ma35d1 mtd nand driver
    - Rename to nuvoton-ma35d1-nand-controller.c.
    - Use switch case instead of if else.
    - Move some parameters to be set during initialization.
    - Fix the ecc.read_page return value issue.
    - Add enable/disable ECC engine before and after reading/writing the page.
    - Return IRQ_NONE if (isr & INT_DMA) == 0.
    - Move the HW ECC related settings to ON_HOST.
    - Move hw_init() to probe.

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'.
