As suggested, this removes the whole cqspi_set_protocol() function, as it is not actually needed: - Checks for unsupported operations are already handled by supports_op(), removing the need to distinguish DTR and non-DTR modes in the buswidth setup - supports_op() ensures that the DTR flags match for all relevant parts of an operation, so op->cmd.dtr can be used instead of copying the flag to the cqspi_flash_pdata - The logic in cqspi_set_protocol() is moved to cqspi_calc_rdreg() and cqspi_write_setup() (with a helper macro CQSPI_OP_WIDTH()) The helper macro checks nbytes instead of buswidth for 0, for consistency with supports_op() etc. Suggested-by: Pratyush Yadav <p.yadav@ti.com> Signed-off-by: Matthias Schiffer <matthias.schiffer@ew.tq-group.com> Link: https://lore.kernel.org/r/20220420155616.281730-1-matthias.schiffer@ew.tq-group.com Signed-off-by: Mark Brown <broonie@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
