Pratyush Yadav 539cf68cd5 spi: spi-mem: add spi_mem_dtr_supports_op() ... spi_mem_default_supports_op() rejects DTR ops by default to ensure that the controller drivers that haven't been updated with DTR support continue to reject them. It also makes sure that controllers that don't support DTR mode at all (which is most of them at the moment) also reject them. This means that controller drivers that want to support DTR mode can't use spi_mem_default_supports_op(). Driver authors have to roll their own supports_op() function and mimic the buswidth checks. See spi-cadence-quadspi.c for example. Or even worse, driver authors might skip it completely or get it wrong. Add spi_mem_dtr_supports_op(). It provides a basic sanity check for DTR ops and performs the buswidth requirement check. Move the logic for checking buswidth in spi_mem_default_supports_op() to a separate function so the logic is not repeated twice.
