Subject: [PATCH v1 1/1] spi: bcm-qspi: Fix BSPI QUAD and DUAL mode support when using flex mode
Date:   Tue,  6 Aug 2019 15:37:50 +0530
Message-Id: <1565086070-28451-1-git-send-email-rayagonda.kokatanur@broadcom.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Fix data transfer width settings based on DT field 'spi-rx-bus-width'
to configure BSPI in single, dual or quad mode by using data width
and not the command width.

Fixes: 5f195ee7d830c ("spi: bcm-qspi: Implement the spi_mem interface")
