Document renesas,poeg-config optional property. The output pins of the general PWM timer (GPT) can be disabled by using the port output enabling function for the GPT (POEG). The HW supports following ways to disable the output pins. 1) Pin output disable by input level detection of the GTETRG{A..D} pins 2) Output disable request from the GPT 3) Pin output disable by user control Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com> --- v7: * New patch Ref: https://lore.kernel.org/linux-renesas-soc/20230306090014.128732-1-biju.das.jz@bp.renesas.com/T/#m07d2c4661d772a705b5a48fd050b7007b830f3eb --- .../bindings/pinctrl/renesas,rzg2l-poeg.yaml | 16 ++++++++++++++++ 1 file changed, 16 insertions(+)
