Subject: [U-Boot] [PATCH v3 03/20] spi: spi-mem: Allow use of spi_mem_exec_op for all SPI modes
Date: Tue, 29 Jan 2019 11:19:50 +0530 [thread overview]
Message-ID: <20190129055007.17376-4-vigneshr@ti.com> (raw)
In-Reply-To: <20190129055007.17376-1-vigneshr@ti.com>
SPI controllers support all types of SPI modes including dual/quad bus
widths. Therefore remove constraint wrt SPI mode from spi-mem layer.
