Add device tree bindings for the RZ/G2L Port Output Enable for GPT (POEG). Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com> --- REF->v1: * Modelled as pincontrol as most of its configuration is intended to be static. * Updated reg size in example. --- .../bindings/pinctrl/renesas,rzg2l-poeg.yaml | 65 +++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/renesas,rzg2l-poeg.yaml
