[PATCH v1 1/1] spi: bcm-qspi: Fix BSPI QUAD and DUAL mode support when using flex mode
From: Rayagonda Kokatanur
Date: Tue Aug 06 2019 - 06:11:53 EST
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")
