Subject: [PATCH] ARM: dts: bcm47094: Add devicetree for D-Link DIR-890L
|
|
|
|
This adds a device tree for the D-Link DIR-890L. This device
|
|
is very similar to D-Link DIR-885L, the differences are detailed
|
|
as a comment in the DTS file.

|
|

|
|
+ *
|
|
+ * Some differences from DIR-885L include a separate USB2 port, separate LEDs

|
+ * for USB2 and USB3, a separate VCC supply for the USB2 slot and no
|
|
+ * router/extender switch is mounted (there is an empty mount point on the
|
