Sometimes when writing large size files to flash in direct/memory mapped mode, it is seen that flash write enable command times out with error: [ 503.146293] cadence-qspi 47040000.ospi: Flash command execution timed out. This is because, we need to make sure previous direct write operation is complete by polling for IDLE bit in CONFIG_REG before starting the next operation. Fix this by polling for IDLE bit after memory mapped write. Fixes: a27f2eaf ("mtd: spi-nor: cadence-quadspi: Add support for direct access mode") Cc: stable@vger.kernel.org Signed-off-by:
