pinctrl: tegra: Display pin function in pinconf-groups
commit 0bbac626d9332ac221dbc2cebfbed2c6a801d381 from https://nv-tegra.nvidia.com/r/3rdparty/canonical/linux-jammy.git jetson_36.3 BugLink: https://bugs.launchpad.net/bugs/2042935 The function that a pin is muxed to can be read from the top-level pinctrl-maps debugfs file. However, this only reflects the values that were specified in device tree, so they will only show deviations from the hardware default setting. Display the current pinmux setting in the per-controller pinconf-groups debugfs file along with the rest of the per-pin configuration settings. http://nvbugs/4328896 http://nvbugs/4307643 Signed-off-by: Thierry Reding <treding@nvidia.com> Tested-by: Luca Ceresoli <luca.ceresoli@bootlin.com> Link: https://lore.kernel.org/r/20230929122101.466266-1-thierry.reding@gmail.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org> (cherry picked from commit bf800ca4 ) Signed-off-by: Prathamesh Shete <pshete@nvidia.com> Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Acked-by: Jacob Martin <jacob.martin@canonical.com> Acked-by: Noah Wager <noah.wager@canonical.com> Signed-off-by: Jacob Martin <jacob.martin@canonical.com> Signed-off-by: Rajeshkumar Ramasamy <rajeshkumar.ramasamy@windriver.com>
