Looking at the code, I'd make the gpio number something like '(offset << 8) | bit' rather than just making up an index. We don't normally have defines for GPIO numbers either. > > Signed-off-by: Robert Marko <robert.marko@sartura.hr> > --- > include/dt-bindings/gpio/tn48m-gpio.h | 26 ++++++++++++++++++++++++++ > 1 file changed, 26 insertions(+) > create mode 100644 include/dt-bindings/gpio/tn48m-gpio.h > > diff --git a/include/dt-bindings/gpio/tn48m-gpio.h b/include/dt-bindings/gpio/tn48m-gpio.h > new file mode 100644 > index 000000000000..4ece4826d746 > --- /dev/null > +++ b/include/dt-bindings/gpio/tn48m-gpio.h > @@ -0,0 +1,26 @@ > +/* SPDX-License-Identifier: GPL-2.0-only */ > +/* > + * GPIO definitions for Delta TN48M CPLD GPIO driver > + * > + * Copyright 2020 Sartura Ltd > + * > + * Author: Robert Marko <robert.marko@sartura.hr> > + */ > + > +#ifndef _DT_BINDINGS_TN48M_GPIO_H > +#define _DT_BINDINGS_TN48M_GPIO_H > + > +#define SFP_TX_DISABLE_52 0 > +#define SFP_TX_DISABLE_51 1 > +#define SFP_TX_DISABLE_50 2 > +#define SFP_TX_DISABLE_49 3 > +#define SFP_PRESENT_52 4 > +#define SFP_PRESENT_51 5 > +#define SFP_PRESENT_50 6 > +#define SFP_PRESENT_49 7 > +#define SFP_LOS_52 8 > +#define SFP_LOS_51 9 > +#define SFP_LOS_50 10 > +#define SFP_LOS_49 11 > + > +#endif /* _DT_BINDINGS_TN48M_GPIO_H */ > -- > 2.31.1 >

CPLD inside of the Delta TN48M does not number GPIOs at all, so in order to ensure numbering lets use bindigs.
