Subject: [U-Boot] [RFC PATCH v2 01/11] spi: spi-mem: Allow use of spi_mem_exec_op for all SPI modes
Date: Tue, 4 Dec 2018 17:56:49 +0530	[thread overview]
Message-ID: <20181204122659.14720-2-vigneshr@ti.com> (raw)
In-Reply-To: <20181204122659.14720-1-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.
