Subject: [PATCH 0/4] gpio: Add gpio latch driver
Date: Mon, 7 Nov 2022 15:45:20 +0100 [thread overview]
Message-ID: <20221107144524.489471-1-s.hauer@pengutronix.de> (raw)
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
