Subject: [PATCH v4 0/2] gpio: Add gpio-latch driver
Date: Thu, 6 Oct 2022 10:30:29 +0200 [thread overview]
Message-ID: <20221006083031.2259006-1-s.hauer@pengutronix.de> (raw)
This round includes the changes suggested by Serge: Instead of hammering
the GPIOs as fast as we can we now have device tree properties to limit
the speed so that slower hardware can work with the driver.
