From 4363aac051fcccb8995b9afb5a4c4cd0a6153c10 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Thu, 21 Jan 2021 17:39:08 +0100 Subject: [PATCH] pinctrl: stm32: bind only the enabled GPIO subnode Bind only the enabled GPIO subnode, to avoid to probe the node "gpio-controller" present in SOC dtsi (disabled by default) but not enabled in the included pincontrol dtsi file. For example, in stm32mp15xxac-pinctrl.dtsi 2 gpio bank are absent: gpioj: gpio@5000b000 gpiok: gpio@5000c000 Then these GPIO are absent in output of command "dm tree" and "gpio status -a" Signed-off-by: Patrick Delaunay Reviewed-by: Patrice Chotard --- drivers/pinctrl/pinctrl_stm32.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/pinctrl/pinctrl_stm32.c b/drivers/pinctrl/pinctrl_stm32.c index 374f76d..6c98538 100644 --- a/drivers/pinctrl/pinctrl_stm32.c +++ b/drivers/pinctrl/pinctrl_stm32.c @@ -409,6 +409,9 @@ static int stm32_pinctrl_bind(struct udevice *dev) dev_for_each_subnode(node, dev) { dev_dbg(dev, "bind %s\n", ofnode_get_name(node)); + if (!ofnode_is_enabled(node)) + continue; + ofnode_get_property(node, "gpio-controller", &ret); if (ret < 0) continue; -- 2.7.4
