Subject: [RESEND PATCH v2 0/5] STM32 pinctrl: Add mux function RSVD

This v2 is a subset of the v1, split-out to simplify the review.

This subset:
- introduces the pinctrl mux function RSVD,
- adds two use cases requiring RSVD,
- minor re-format of the dt-bindings.

Changes v1 -> v2 subset:
- rebased on v6.16-rc1,
- added use cases of the new mux function RSVD,
- added Reviewed-by: on 2/5 (former 04/14 in v1),
- added commit to re-format the dt-bindings,
- Link to v1: https://lore.kernel.org/lkml/20241022155658.1647350-1-antonio.borneo@foss.st.com/

  ARM: dts: stm32: Add pinmux for CM4 leds pins
  ARM: dts: stm32: Add leds for CM4 on stm32mp15xx-ed1 and
    stm32mp15xx-dkx
  dt-bindings: pinctrl: stm32: Add missing blank lines

Fabien Dessenne (2):
  pinctrl: stm32: Handle RSVD pin configuration
  dt-bindings: pinctrl: stm32: Add RSVD mux function
