Commit Message

Linus Walleij Nov. 8, 2023, 2:33 p.m. UTC 
This changes the GPIOs defined in the device tree to recommended
practice, which is also what the Linux NAND GPIO driver is actually
using.

In the process, fix up the CE and WP lines to be active low, as is
required for proper hardware description.
