Subject: [PATCH 08/10] spi: fsl-espi: remove usage of 'delay_usecs' field
Date: Mon, 8 Mar 2021 16:55:00 +0200 [thread overview]
Message-ID: <20210308145502.1075689-9-aardelean@deviqon.com> (raw)
In-Reply-To: <20210308145502.1075689-1-aardelean@deviqon.com>
The 'delay_usecs' field is being removed from the spi_transfer struct.
This change removes it from the SPI FSL ESPI driver.
