Subject: [PATCH v3 15/21] spi: dw: Move num-of retries parameter to the header file
Date: Fri, 2 Oct 2020 01:28:23 +0300 [thread overview]
Message-ID: <20201001222829.15977-16-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20201001222829.15977-1-Sergey.Semin@baikalelectronics.ru>
The parameter will be needed for another wait-done method being added in
the framework of the SPI memory operation modification in a further
commit.
