Subject: [PATCH v3 0/4] mtd: rawnand: stm32_fmc2: Add NAND Write Protect support

This patchset adds the management of the WP# signal in FMC2 driver.
WP will be disabled in probe/resume callbacks and will be enabled
in remove/suspend callbacks.

This patchset also fixes a conflict on wp-gpios property between
MTD and NVMEM.

Changes in v3:
 - add a fixes tag in patches 3 and 4.
 - rename skip_wp_gpio by ignore_wp in nvmen_config.

Changes in v2:
 - add Rob Acked-by for the bindings part.
 - rework the proposal done to fix a conflict between MTD and NVMEM on
   wp-gpios property.
