| Subject: spi: atmel-quadspi: Fix the buswidth adjustment between spi-mem and controller |
| |
| From: Tudor Ambarus <tudor.ambarus@microchip.com> |
| |
| commit 8c235cc25087495c4288d94f547e9d3061004991 upstream. |
| |
| Use the spi_mem_default_supports_op() core helper in order to take into |
| account the buswidth specified by the user in device tree. |
