# Configuration file for pinctrl generation (F1 series only).
#
# This file contains a list of pin configuration templates used to generate the
# pinctrl files. Each entry can have the following fields:
#
#   - name (mandatory): This is the pin function name, e.g. UART_TX. It is used
#     to group pin configurations alphabetically in the generated pinctrl files.
#
#   - match (mandatory): This is a regular expression used to match against
#     STM32 xml database pin configuration names. The regular expression should
#     be as precise as possible. Note that it needs to be escaped here in the
#     configuration file.
#     Note: Specific "ANALOG" value allows generation of analog pins
#     configuration
#
#   - mode (mandatory): Mode setting (analog, alternate, input). Mode needs to
#     be set according to the following rules:
#       * Pin operates in analog configuration: analog
#       * Pin operates in alternate function input configuration: input
#       * Pin operates in alternate function output/bidirectional configuration:
#         alternate
#
#   - bias (optional): Bias setting (disable, pull-up, pull-down). This setting
#     only applies to "input" mode. Equivalent to "disable" (a.k.a floating) if
#     not set.
#
#   - drive (optional): Drive setting (push-pull, open-drain). Equivalent to
#     "push-pull" if not set.
#
#   - slew-rate (optional): Slew rate setting (max-speed-10mhz, max-speed-2mhz,
#     max-speed-50mhz). Equivalent to "max-speed-10mhz" if not set.
#
#   - variant (optional): Defines an alternative pin configuration. This is used
#     to provide multiple configurations of a pin function (slave, master,
#     low-power, ...).
