Subject: [PATCH 5/5] spi: Parse hold/inactive CS delay values from the DT
Date: Wed, 4 Jan 2023 18:36:31 +0900 [thread overview]
Message-ID: <20230104093631.15611-6-marcan@marcan.st> (raw)
In-Reply-To: <20230104093631.15611-1-marcan@marcan.st>
From: Janne Grunau <j@jannau.net>
Now that we support parsing the setup time from the Device Tree, we can
also easily support the remaining hold and inactive time delay values.
