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

GPIOZ0: unused : 0 [ ]
GPIOZ1: unused : 0 [ ]
GPIOZ2: unused : 0 [ ]
