[PATCH 0/4] gpio: Add gpio latch driver

[Sascha Hauer]

This adds a gpio-latch driver recently added to Linux, see
https://lore.kernel.org/lkml/20221007114647.2723457-2-s.hauer@pengutronix.de/T/

This is basically the same driver adjusted for barebox. As a preparation
we have to add some bitmap helpers needed for the driver.

Sascha Hauer (4):
  bitmap: Implement bitmap_*zalloc()
  bitops: include linux/types.h
  bitops: implement assign_bit()
  gpio: Add gpio latch driver
