From 87006dd600e36e05a2bd978c112a0aa883713c00 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 22 Apr 2015 16:14:37 -0700 Subject: [PATCH] phy: phy-core: allow specifying supply at port level Multi-port phys may have per port power supplies. Let's change phy core to look for supply at the port level when multiple ports are specified. To keep compatibility with the existing device tree board descriptions for single-port phys we will continue looking up the power supply at the parent node level Signed-off-by: Dmitry Torokhov Signed-off-by: Arun Ramamurthy Reviewed-by: Ray Jui Reviewed-by: Scott Branden Signed-off-by: Kishon Vijay Abraham I --- drivers/phy/phy-core.c | 23 ++++++++++------------- 1 file changed, 10 insertions(+), 13 deletions(-) diff --git a/drivers/phy/phy-core.c b/drivers/phy/phy-core.c index 964a84d5a580..5f729bb0788f 100644 --- a/drivers/phy/phy-core.c +++ b/drivers/phy/phy-core.c @@ -683,16 +683,6 @@ struct phy *phy_create(struct device *dev, struct device_node *node, goto free_phy; } - /* phy-supply */ - phy->pwr = regulator_get_optional(dev, "phy"); - if (IS_ERR(phy->pwr)) { - if (PTR_ERR(phy->pwr) == -EPROBE_DEFER) { - ret = -EPROBE_DEFER; - goto free_ida; - } - phy->pwr = NULL; - } - device_initialize(&phy->dev); mutex_init(&phy->mutex); @@ -706,6 +696,16 @@ struct phy *phy_create(struct device *dev, struct device_node *node, if (ret) goto put_dev; + /* phy-supply */ + phy->pwr = regulator_get_optional(&phy->dev, "phy"); + if (IS_ERR(phy->pwr)) { + ret = PTR_ERR(phy->pwr); + if (ret == -EPROBE_DEFER) + goto put_dev; + + phy->pwr = NULL; + } + ret = device_add(&phy->dev); if (ret) goto put_dev; @@ -721,9 +721,6 @@ put_dev: put_device(&phy->dev); /* calls phy_release() which frees resources */ return ERR_PTR(ret); -free_ida: - ida_simple_remove(&phy_ida, phy->id); - free_phy: kfree(phy); return ERR_PTR(ret); -- 2.34.1
