Since NXP LPC32xx SoC support in the Linux kernel strictly depends on
device tree support, the unused platform data support can be removed
from the LPC32xx NAND MLC and SLC drivers.

Sashiko raises a build issue due to the cleanup missing one use of a
header. Can you please check?

sure, from its report [1] I see that Sashiko bot verifies the changes
against today's outdated v7.2, and therefore it produced a false positive
error, since v7.3-rc1 contains the commit d6ef4391897d ("ARM: lpc32xx:
remove a few manually populated OF devices").
There should be no build errors introduced by this series, thanks for review.

sure, from its report [1] I see that Sashiko bot verifies the changes
against today's outdated v7.2, and therefore it produced a false positive
error, since v7.3-rc1 contains the commit d6ef4391897d ("ARM: lpc32xx:
remove a few manually populated OF devices").

Applied to nand/next, thanks!
[1/2] mtd: rawnand: lpc32xx_slc: Remove platform data support
commit: e18c514e9c1ff330bec87fd62341251d041e7443
[2/2] mtd: rawnand: lpc32xx_mlc: Remove platform data support
commit: def559a215699aa2f2d8ef98f30156b9d562a154
Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).
Kind regards,
