Add "pinmux-select" to debugfs which will activate a pin function for a given pin group: echo "<group-name function-name>" > pinmux-select The write operation pinmux_select() handles this by checking that the names map to valid selectors and then calling ops->set_mux(). The existing "pinmux-functions" debugfs file lists the pin functions registered for the pin controller. For example: function: pinmux-uart0, groups = [ pinmux-uart0-pins ] function: pinmux-mmc0, groups = [ pinmux-mmc0-pins ] function: pinmux-mmc1, groups = [ pinmux-mmc1-pins ] function: pinmux-i2c0, groups = [ pinmux-i2c0-pins ] function: pinmux-i2c1, groups = [ pinmux-i2c1-pins ] function: pinmux-spi1, groups = [ pinmux-spi1-pins ] To activate function pinmux-i2c1 on group pinmux-i2c1-pins: echo "pinmux-i2c1-pins pinmux-i2c1" > pinmux-select Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Reviewed-by: Tony Lindgren <tony@atomide.com> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Tested-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Drew Fustini <drew@beagleboard.org> Link: https://lore.kernel.org/r/20210302053059.1049035-3-drew@beagleboard.org Signed-off-by: Linus Walleij <linus.walleij@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.
