Each pinctrl group contains one or more pinmux subnodes to list needed pins and their configurations. By supporting multiple subnodes, we can configure different pin characteristics (driving/pull-up/pull-down/etc.) in a pinctrl group. Update the mt8192 pinctrl dt-binding to add the missing pinctrl group node that wraps the pinmux subnodes and update the example at the end. While at it, also remove the example embedded in the description since it is redundant to the already supplied example at the end. This same change was done for mt8195 in commit 79dcd4e840cc ("dt-bindings: pinctrl: mt8195: add wrapping node of pin configurations"). Signed-off-by: Nícolas F. R. A.
