From 6a3c609feb11d2d5be986d578623cf7a2328e9f1 Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Wed, 6 Apr 2022 16:36:03 +0300 Subject: [PATCH] spi: atmel-quadspi: Fix the buswidth adjustment between spi-mem and controller 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.
