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. https://lore.kernel.org/all/CABGWkvoLDez=yWzpXgO2s+gVs0aUDCEUAYSa8zo_+wGVf4L...
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
Balamanikandan Gunasundar (9): nand: atmel: Add DM based NAND driver nand: atmel: Add pmecc driver mfd: syscon: Add atmel-matrix registers definition memory: atmel-ebi: add Atmel EBI (External Bus Interface) driver mfd: syscon: atmel-smc: Add new helpers to ease SMC regs manipulation configs: at91: sam9x60ek: Enable DM based nand driver ARM: dts: at91: sam9x60: Add nodes for EBI and NAND ARM: dts: at91: sam9x60ek: Enable NAND support board: sam9x60ek: remove nand init from board file
Was suppose to get pick on top on nand changes

Hi Bala,
I have applied the series to u-boot-at91/next here : https://source.denx.de/u-boot/custodians/u-boot-at91/-/tree/next
Can you double check that everything is fine ? I have done some edits on rebasing.
Otherwise, the series will go as a PR to 2023.04 from the at91 tree once the merge window opens.
Thanks, Eugen
