Rob Herring ac9ba7dc86 phy: Convert to using %pOFn instead of device_node.name
In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.

Johan Hovold 046046737b phy: tegra: fix device-tree node lookups
Fix child-node lookups during probe, which ended up searching the whole
device tree depth-first starting at the parents rather than just
matching on their children.

To make things worse, some parent nodes could end up being being
prematurely freed (by tegra_xusb_pad_register()) as
of_find_node_by_name() drops a reference to its first argument.

Baoyou Xie 713b3ce9a3 phy: tegra: mark tegra_xusb_lane_lookup_function() static
We get 1 warning when building kernel with W=1:
drivers/phy/tegra/xusb.c:104:5: warning: no previous prototype for 'tegra_xusb_lane_lookup_function' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is
declared and don't need a declaration, but can be made static.
So this patch marks it 'static'.

drivers/phy/tegra/xusb.c:981:6: warning: no previous prototype for 'tegra_xusb_padctl_put' [-Wmissing-prototypes]

drivers/phy/tegra/xusb.c:1008:5: warning: no previous prototype for 'tegra_xusb_padctl_usb3_set_lfps_detect' [-Wmissing-prototypes]

In fact, these functions are declared in linux/phy/tegra/xusb.h,
so this patch adds missing header dependencies.

Thierry Reding 53d2a715c2 phy: Add Tegra XUSB pad controller support
Add a new driver for the XUSB pad controller found on NVIDIA Tegra SoCs.
This hardware block used to be exposed as a pin controller, but it turns
out that this isn't a good fit. The new driver and DT binding much more
accurately describe the hardware and are more flexible in supporting new
SoC generations.
