Convert all register accesses from etm4x driver to use a wrapper to allow switching the access at runtime with little overhead. co-developed by sed tool ;-), mostly equivalent to : s/readl\(_relaxed\)\?(drvdata->base + \(.*\))/etm4x_\1_read32(csdev, \2) s/writel\(_relaxed\)\?(\(.*\), drvdata->base + \(.*\))/etm4x_\1_write32(csdev, \2, \3) We don't want to replace them with the csdev_access_* to avoid a function call for every register access for system register access. This is a prepartory step to add system register access later where the support is available.

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.
