Currently the sm501 mfd driver can be compiled without any dependencies, but through the use of dma_declare_coherent it really depends on having DMA and iomem support. Normally we don't explicitly require DMA support as we have stubs for it if on UML, but in this case the driver selects support for dma_declare_coherent and thus also requires memmap support. Guard this by an explicit dependency. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Lee Jones <lee.jones@linaro.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.
