Subject: [PATCH v2 1/3] pinctrl: sh-pfc: add new flags into struct sh_pfc_pin_config
Date: Thu,  8 Aug 2019 15:19:01 +0900	[thread overview]
Message-ID: <1565245143-15018-2-git-send-email-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <1565245143-15018-1-git-send-email-yoshihiro.shimoda.uh@renesas.com>

To clean/modify the code up later, this patch just adds new flags
"mux_set" and "gpio_enabled" into the struct sh_pfc_pin_config.
