Subject: [PATCH 35/90] mtd: nand: sunxi: Pass the device to the init function

This more closely matches the U-Boot driver to the Linux version.

Series-to: sunxi

Cover-letter:
mtd: nand: sunxi: Convert to devicetree and the driver model
This series converts the sunxi NAND driver to get its resources (clocks,
resets, pins) from the devicetree, and probe using the driver model.

In addition to the immediate cleanup, this allows backporting more
patches (bugfixes, newer SoC support) from the Linux driver.
END
