[PATCH v3 0/9] Add DM support for atmel NAND driver

[Balamanikandan Gunasundar]

Change include:

- Adapt GPIO descriptor apis for U-Boot. Use
  gpio_request_by_name_nodev, dm_gpio_get_value etc.
- Use U_BOOT_DRIVER instead of platform_driver.
- Replace struct platform_device with struct udevice
- Check the status of nfc exec operation by polling the status
  register instead of interrupt based handling
- DMA operations not supported. Remove it
- Adapt DT parsing to U-Boot APIs

Note:

I need some advise or help in alligning the DT with Linux as per the
discussion.

v3:

- Do not check return values while requesting optional gpio pins
  (cs-gpios and rb-gpios)
- Commit message for adding SMC helper function reworded
- The unwanted indentation in the DT is fixed. The changes are made on
  top of "275943dba4 ARM: dts: at91: sam9x60ek: fix indentation for
  pinctrl sub-nodes"

v2:

- Add linux reference version in the commit message from which the
  driver is ported from
- Reword the commit message to describe the changes clearly
