Subject: [PATCH v3 3/4] pinctrl: pinctrl_stm32: Populate uc_priv->name[] with pinmux node's name
Date: Tue, 30 Aug 2022 14:09:13 +0200	[thread overview]
Message-ID: <20220830120914.2329522-4-patrice.chotard@foss.st.com> (raw)
In-Reply-To: <20220830120914.2329522-1-patrice.chotard@foss.st.com>

Populate uc_priv->name[] with pinmux node's name in order to indicate
the pinmuxing's name in case GPIO is configured in alternate.

For example, for STM32 SoC's based platform, "gpio status" command
output :

  before
    Bank GPIOZ:
      GPIOZ0: unused : 0 [ ]
      GPIOZ1: unused : 0 [ ]
      GPIOZ2: unused : 0 [ ]
      GPIOZ3: unused : 0 [ ]
      GPIOZ4: func
      GPIOZ5: func
      GPIOZ6: unused : 0 [ ]
      GPIOZ7: unused : 0 [ ]
      GPIOZ8: unknown
      GPIOZ9: unknown
      GPIOZ10: unknown
      GPIOZ11: unknown
      GPIOZ12: unknown
      GPIOZ13: unknown
      GPIOZ14: unknown
      GPIOZ15: unknown

  After
    Bank GPIOZ:
      GPIOZ0: unused : 0 [ ]
      GPIOZ1: unused : 0 [ ]
      GPIOZ2: unused : 0 [ ]
      GPIOZ3: unused : 0 [ ]
      GPIOZ4: func i2c4-0
      GPIOZ5: func i2c4-0
      GPIOZ6: unused : 0 [ ]
      GPIOZ7: unused : 0 [ ]
      GPIOZ8: unknown
      GPIOZ9: unknown
      GPIOZ10: unknown
      GPIOZ11: unknown
      GPIOZ12: unknown
      GPIOZ13: unknown
      GPIOZ14: unknown
      GPIOZ15: unknown
