Add MUX_USB_* and MUX_TYPEC_* state constant defines, which can be used by USB device/host, resp. Type-C polarity/role/altmode mux drivers and consumers to ensure that they agree on the meaning of the mux_control_select() state argument. Signed-off-by: Hans de Goede <hdegoede@redhat.com> --- Changes in v2: -Start numbering of defines at 0 not 1 -Use a new usb.h header, rather then adding these to consumer.h -Add separate MUX_USB_* and MUX_TYPEC_* defines --- include/linux/mux/usb.h | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 include/linux/mux/usb.h diff --git a/include/linux/mux/usb.h b/include/linux/mux/usb.h new file mode 100644 index 000000000000..44df5eca5256 --- /dev/null +++ b/include/linux/mux/usb.h @@ -0,0 +1,32 @@ +/* + * mux/usb.h - definitions for USB multiplexers + * + * Copyright (C) 2017 Hans de Goede <hdegoede@redhat.com> + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ +#ifndef _LINUX_MUX_USB_H +#define _LINUX_MUX_USB_H + +/* Mux state values for USB device/host role muxes */ +#define MUX_USB_DEVICE (0) /* USB device mode */ +#define MUX_USB_HOST (1) /* USB host mode */ +#define MUX_USB_STATES (2) + +/* + * Mux state values for Type-C polarity/role/altmode muxes. + * + * MUX_TYPEC_POLARITY_INV may be or-ed together with any other mux-state as + * inverted-polarity (Type-C plugged in upside down) can happen with any + * other mux-state. + */ +#define MUX_TYPEC_POLARITY_INV BIT(0) /* Polarity inverted bit */ +#define MUX_TYPEC_DEVICE (0 << 1) /* USB device mode */ +#define MUX_TYPEC_HOST (1 << 1) /* USB host mode */ +#define MUX_TYPEC_HOST_AND_DP_SRC (2 << 1) /* USB host + 2 lanes DP src */ +#define MUX_TYPEC_DP_SRC (3 << 1) /* 4 lanes Display Port src */ +#define MUX_TYPEC_STATES (4 << 1) + +#endif /* _LINUX_MUX_TYPEC_H */ -- 2.13.5
